The ultimate sleeper
 
If you were to build up a realistic sleeper, what would you do? I'm not talking about buying the car, but building one up, that one wouldn't assume to be quick. I.E....buying a GNX and/or building up a GN/GNX.

Here's my thoughts, hopefully to turn in to a realistic project:

1. Start with a 1997 Olds Cutlass Supreme sedan
2. Remove crappy 3100 V6 and 4T60-E transmission
3. Remove front brake hardware
4. Remove all four wheels and tires
5. Obtain either a L67 (Supercharged GM 3800 V6) equipped donor car, or entire powerplant stuff, including engine, trans, axles, wiring...stuff like that
6. Rebuild the L67 motor with a better valvetrain, P&P heads, performance cam, computer, headers, smaller pulley, CAI, full exhaust
7. Build up the 4T65-E HD transmission to take more torque
8. Install cross drilled front rotors, and possibly four piston front calipers, use race pads
9. Install slotted rear rotors, and replace the crappy GM rear calipers with something else, use race pads
10. Install Mille Miglia HT-3 18x8 rims in Carbon Grey, along with 225/40-R18 Bridgestone Potenza S-O3 Pole Position tires
11. Install various but necessary engine monitoring guages to keep things in check.
12. Keep up with Corvettes on the dragstrip!

This should be a $6000 or so project, yielding me a new motor, transmission, and other go fast goodies. The only outward cues will be the 18" wheels, and the upgraded brake hardware poking through.

bigbubba_21 04-20-2003 11:04 AM

Call me strange but i wanna build up an 4door Aspen, that car would be the ultimate sleeper :D

DEI37 04-20-2003 11:25 AM

I could see a built 360 in that car's future. Sounds like fun to me!

laconic1 04-20-2003 11:32 AM

That Olds should be doable, the only thing I've heard is that at about 300 hp the trans gives up no matter what is done. Since the stock supercharged 3800 is 240 hp those mods would probably get you right to that point pretty quick.

0001 04-20-2003 02:15 PM

No no. Ultimate sleeper is a beater 80's Volvo DL.

I've seen this done believe it or not. Car looked like total ass, but I noticed the guy had a rollbar on the inside as he burned past me.

mighty mouse 04-20-2003 02:25 PM

I have an 86 Olds Cutlass 4 door, already has a 307 V8 in it so the swap to a 406SB or 454BB may be done in a couple years behind the other projects. I don't think many would see the column shifted auto 4 door grandma car coming.

wraithhibn 04-20-2003 02:50 PM

I want to get a 92-95 Taurus SHO and build it up, the motor will go 150 stock, until the computer cuts it off. souped up it would be awesome, because its a family car. Maybe the 96-99 SHO with the V8 would be better.

Dougie 04-20-2003 03:32 PM

im with ya on the aspen... (i thought i was the only sicko)

only a 2 door, 440, 4 spd, Black primer.

DEI37 04-20-2003 03:54 PM

The V8 SHO sucked big time. And there is no aftermarket for it really. Stick with the Yamaha powered V6 SHO...much better engine, and aftermarket.
The 86 Cutlass sounds like it'd be some fun. Personally, I'd stick a 427BB in it!

merkerguitars 04-20-2003 03:57 PM

I want to do a the same thing to my cadillac since the factory 4.1L doesn't get good gas mileage and it only has about 140hp and is slow.. I was thinking when I got the cash put some baer brakes on it. And then put a 3.8 supercharged engine in. It would also making working on it a little more pleasant too.

reconmike 04-20-2003 04:12 PM

mine is being cut up now...
1985 honda civic hatchback......
going in is SB chevy 350 with a front wheel drive olds tornado trans,
the honda motor and trans are out and we are welding the the "new" sub frame up soon.

spring snuck up on me and it is time to start heading to raceway park, englishtown nj to start bracket racing my 97 LT1 firechicken

mighty mouse 04-20-2003 07:31 PM

I thought the 86 Cutlass could be cool, just gonna depend on money i.e. how much we spend on the other cars first. Maybe a 454+ cubic inch engine with a centrifugal blower. No one would see the 700hp comin. hehe

Ashton 04-20-2003 07:54 PM

My friend took a little 74 Fiat and stuffed a warmed over 350 in it, just looking at it you wouldn't think anything of it... just a wussy Fiat, but it had to have 100 pounds of lead in the trunk to get any sort of traction..... of course the throaty V8 dual exhaust kind of gave it away though :)

shakran 04-20-2003 07:59 PM

best sleeper I ever saw was a twin-engined Econoline panelvan. Thing had a V-10 running the front wheels and a V-10 running the rears. Both supercharged. . . .that sucker was FAST.

BonneFan 04-20-2003 08:52 PM

I have considered droppin an L67 Series II 3800 with an M90 Supercharger, plus finding the proper tranny and PCM/ECM/wiring. And putting it into my 1989 Bonneville SE...now, thats a sleeper.

fastom 04-20-2003 10:31 PM

that little V6 would be no match for many of the sleepers i've seen. 600-700hp in a clapped out beater with whitewalls :p

Big block Chevy in a mid 60's Rambler American 4 door, stock wheels and quiet exhaust.

Restored Falcon with wire hubcaps, and huge power 5.0L disguised to look like the stock 260.

Aspen? Howzabout an early 80's St Regis... 4 door, ex fuzz, 440 with N2O

TR7 with 350, little 13" rims.;)

thadon 04-21-2003 02:47 PM

How about a Volvo w/ a LS1 V8. I ran across a site that had conversion kits to turn POS diesel Volvos into kick azz V8 street sleepers. My roomate has a 88 Volvo Wagon that the engine just took a dump on him adn I am thinking about buyinh the car from him for like $500 then dropping a V8 under the hood and it would be one killer ride for under $6k

MexicanOnABike 04-21-2003 04:16 PM

interesting idea.. go for it !! then post pics!

joe spade 04-30-2003 09:20 PM

Yup, can't waitto see that one, try 0% financing, a lot less hassle.

The cool thing about turning a diesel into a sleeper is as long as you register it while it's running you never have to have it smog tested...... you can take a registered diesel and drop a killer drive train into it and never have to worry about aftermarket parts or stuff that wouldn't pass the visual inspection. You could go nuts and build a Rat motor for it and unless a cop looked under the hood you would get away with it...... :D

rockogre 05-01-2003 06:49 AM

I built a sleeper out of my last Suburban.

Suburban???

1985 half ton, brown and tan.

Yep. Yanked the motor and trans. Built a roller motor, flat top pistons, hotter cam, high flow oil pump. Trashed the exaust and had a custom dual exhaust built and installed along with high flow Dynamax mufflers. Used a Holley fuel injection kit, and of course a K&N air filter. Three angle valve job. Had the trans custom rebuilt and fine tuned the shift rpms.

It would smoke the tires with just me in it. I just loved taking smart assed folks at stop lights. Passing on the interstate was a breeze. Hated to give it up but on to better and bigger things.

shakran 05-01-2003 07:02 AM

nothing too strange about a sleeper suburban. Liegenfelter made one in the late 90's that was fast as hell. Car and Driver did a nice write up on it.

MrGone 05-01-2003 03:40 PM

maxima
choose if you want an auto or manual
put some sticky tires on it

cheap route:
InJen Intake
Y-pipe
B-pipe (not so big)
UDP
nitrous

=12second car

fun route:
T04B Turbo
Spearco FMIC
Management Electronics
UDP

=xx second car depending on boost.

yeah, ive forgotten some things, but the you would be running on a stock engine with minor modifications to the engine.

MSD 05-02-2003 12:33 PM

A friend of mine is planning to drop a Spoon twin turbo into an Odyssey, replace the axles and tranny, and throw on a NOS fogger system. He thinks it's a great idea, I'll believe it when I see it.

The V8 SHO's were pieces of crap. Go with the Yamaha built engine instead.

RaDiAn 05-02-2003 05:38 PM

Has any seen the Dogde Omni that has the turbo? I forget what it's called exactly. Some kid I knew had on all done up. I had one look at it and said that's not much to look at. Then he had shown me what was hiding under the H@@D! Yikes! Then he ask me if I would like to go for a ride. That was the badest Omni ride I ever had!!!! Later he had told me all of the MODS that had been done. He had to have special half shafts made because he was breaking them on the track.....what a great ride, it didn't look like much, but it flew. He was very easily eating up the 5.0 stangs, he had a harder time with the BBlocks........Just thought I'd share my story!

pwhale 05-05-2003 06:13 AM

I think you're on the right track. Volvo cars have always been the stereotypical safe cars. Whether they are just solid tank-like vehicles like the '76-'93 240 series or the supertechnological airbag laden cars like the S60 and S80, they've always been associated with safety over performance. That said the ultimate sleeper will be (when they debut) the S60R, with an aftermarket ECU and exhaust system. A Volvo with ~350 hp is definitely a sleeper. It can be done, look at the '94-'00 850/S70 Turbos with modded 280hp! Boy, will the kid in the Civic be mad when he gets dusted by an 8 year old Volvo!

word.
I know a guy who put a 302 into a early 240 wagon. Talk about sleeper. The only obvious signs the car was not stock was the larger than usual 2.5" exhaust.....and the sound it made when fired up....

theguyondacouch 05-19-2004 10:22 AM

Pinto wagon, 302 roller motor with a crazy hot cam. Drop a narrowed 9 inch in it with 4:10's... nice

Was looking real good till you got to your wheels. If you want to have a sleeper keep the wheels and tires stock like. A set of 16" steel wheels and some 225/55R16s or similiar will go a long way to maintaining the "he'll never take me look" while maintaining decent grip. Might even be lighter than those 18" wheels. Or a set of GM factory 16" aluminium mags, lots of stuff came with 16" wheels over the years.

My favourite sleeper was a buddy's satilitte sedan. Had a worked over 413 pushing a 3.90 rear thru a 4sp. Had better than 400hp at the rear wheels and would take just about anything on the street while still looking like something grandma drove.

matteo101 05-19-2004 01:38 PM

You guys wanna see a sleeper, THIS IS A SLEEPER.

He trashed his crop of pot plants when the DEA came knocking at his door, so he never got the money to do it.

PDOUBLEOP 05-20-2004 08:41 AM

If you try to race someone with a car that looks like a POS, they'll know you've got a sleeper. What do you think about a Syclone with a Busch series aluminum V-6. With proper accessories, it'll run low 10's w/out nitrous.

WarWagon 05-20-2004 08:03 PM

I just e-mailed the guys at Dream Car Garage about a car featured briefly in one of their segments. A Plymouth Reliant that had been converted to RWD with a 440 in it...

lt1s10 05-20-2004 11:35 PM

A couple that I've seen that have impressed me are the people with the turbo dodge caravans and the k-cars. Many of them are running in the 12s.

Also seen a few late 70s volkswagen buses running the porsche 3.0s. Those are about as unaerodynamic as it gets. And they haul with the 3.0 in them. It's also not a real difficult swap.

WarWagon 05-21-2004 07:04 AM

Just so you guys know, Tom Hnatiw from DCG sent me back an e-mail. The Plymouth Reliant with the fuel injected 440 does exist, and belongs to Jason Roberts, who is shop manager for Legendary Motorcar.

neddy65 05-22-2004 03:38 PM

a buddy dropped a 350 chevy engine in a b2000. This truck was a serious sleeper cause the guy left it all primer spotted and had good tires on stock wheels. Had to talk him out of the stacks for his exhaust though cause that was going too far.

WarWagon 05-22-2004 05:27 PM

Hell no, stacks and flappers are the way to go.

Crunchy Nipple 05-26-2004 12:30 AM

I read a while back about a guy who took 80's vw bug, pulled the body and the engine out, cut the rear last hal of the frame off and welded on the front end (chasis and engine only) of a '72 cadiliac eldorado. He worked a scoop to go down through the floor to feed the air intake and cool the radiatior. Built a box around the engine, which took up all of the back seat, covered it with carpet. Now think of it You have a Bug that looks stock except for the funny looking speaker box in the back, but when you floor it you have all of the might of a 367 GHP 8.1 liter engine behind you. That is one hell of a power to weight raito. I thought it was nifty.

That's with the uh "factory" turbo 4. Dodge made a stage III kit that gave you better than 270hp.

That'd be a tight squeeze. A 440 is pretty tall.

Have to get a look at that episode I just happen to have a dodge big block and a 85 new yorker sitting around.

Nimisys 05-27-2004 05:24 PM

best sleeper i have ever seen was a Geo Metro Hatchback. white faded paint, 13" pizza wheels, the whole POS car thing. However under the hood was a 13B TII engine out of a 88 AE Rx-7. kinda of scary to see a metro pass you at 120mph.

irseg 05-28-2004 07:05 PM

My Lincoln Mark VIII has excellent sleeper qualities. It looks like your typical car that grandma would drive to church, and alas it's typically used that way. But has a 280hp V8 that's basically the same engine that went on to be used in the Mustang Cobra. Runs very low 15's in the 1/4 mile. Not insanely fast, but enough to surprise the hell out of a lot of people.

My slightly modified '88 Thunderbird Turbo Coupe is a good sleeper too. I pissed off my boss when I outran his brand new Navigator with my old POS 4-banger. He just drove by with his middle finger in the air and never brought it up again. :D

matteo101, I emailed those pictures to a couple friends of mine. One loves Cadillacs, the other is a VW fanatic. They both got a kick out of it. Is there any info available with the details of the swap? The pics are cool but I'd like to read about what was involved.

spano24 05-30-2004 07:47 PM

I actually just finished my sleeper project. I got excited whe i saw this topic.


I started off with a 91' 240 volvo. It had 200,000 on the motor and was about beat. Picked it up for $150 and no rust on the car (unheard of for upstate NY)

So i buy a little kit from converse engineering. Its all the necessary bits for a mustang 5.0 swap. I bought a 87 5.0 HO donor car. I took the engine down to the block and rebuilt it with new cylinders, rings, lifters, valves, had the intake/exhaust ported, got a new head and Bought a vortech supercharger for it.

Tossed it into the 240, got a custom drive shaft and use a 8'' ford rear end.

I run 6 lbs of boost and run about a 11.4 at the 1/4

Its a head turner, I get kicks out of spanking up on kids in their little 4 bangers and even taking out other american muscle. The looks on peoples faces are priceless.

WarWagon 05-30-2004 10:49 PM

Mind if I ask how you got that 8.8 rear in there? More or less in terms of how your control arms are setup up.

I don't know too much about the swap. I read that it took three weaks only working nights and weekends. It is really impressive. Cam (the creator) is actually getting alot better from what I have read, he is out of his coma, and is talking and remembering alot of things. We he has recovered I can get the scoop from him.

Zipperhead 05-31-2004 04:05 PM

There was a POS Dodge Omni (turbo) here in town that pulled the pants off an '03 Viper at our local track last year. Funniest thing I've ever seen. And street legal. It was one of the ugly Omnis that looked kind of like an old VW rabbit.

never seen or heard of an omni before...what year where they?

etla 06-08-2004 10:08 AM

Turbo omnis were available from 84-87. Some '87s featured a hybrid stage I/II kit that produced 187hp. Not bad in a car with a 2300 lb curb weight.

The original factory (and still ultimate) sleeper car was the 1986 Dodge Omni GLH and its Shelby GLHS counterpart.

Sorry to those posts immediately above me. I didn't read before I posted. Obviously, I agree with you about the Omni.

Here's my thoughts, hopefully to turn in to a realistic project:

1. Start with a 1997 Olds Cutlass Supreme sedan
2. Remove crappy 3100 V6 and 4T60-E transmission
3. Remove front brake hardware
4. Remove all four wheels and tires
5. Obtain either a L67 (Supercharged GM 3800 V6) equipped donor car, or entire powerplant stuff, including engine, trans, axles, wiring...stuff like that
6. Rebuild the L67 motor with a better valvetrain, P&P heads, performance cam, computer, headers, smaller pulley, CAI, full exhaust
7. Build up the 4T65-E HD transmission to take more torque
8. Install cross drilled front rotors, and possibly four piston front calipers, use race pads
9. Install slotted rear rotors, and replace the crappy GM rear calipers with something else, use race pads
10. Install Mille Miglia HT-3 18x8 rims in Carbon Grey, along with 225/40-R18 Bridgestone Potenza S-O3 Pole Position tires
11. Install various but necessary engine monitoring guages to keep things in check.
12. Keep up with Corvettes on the dragstrip!

This should be a $6000 or so project, yielding me a new motor, transmission, and other go fast goodies. The only outward cues will be the 18" wheels, and the upgraded brake hardware poking through.


There were no 97 cutlass supreme 4 doors that used the "crappy 3100" V6 engine, no 4t60-e transaxle as all 97 cutlass were still rear wheel drive. None came with rear disk brakes and although it is possible to convert to disk brakes that is not going to make the 87 sedan a front driver. If you started with a 90 model you could do these mods and be on your way. I have an 88 base supreme 2 door that I sold new in 88 and bought back from the owner and it is about as base as the got that year. It came stock with a 2.8, auto overdrive, "am" radio, crank windows, pie plate wheel covers on 14" wheels, column shift, P-steering, P-brakes and no air conditioner, etc. Now this is going to be a sleeper with a built-up L67, 4t65e-hd, quick ratio steering, later 11.25" front rotors, replacement rear disks and calipers, upgrade pads and struts, HD radiator, headers and exhaust from borla with intake from K and N cone infront of the rad, 16" stock "International" wheels and tires. In that way it will appear "stock" until the performance is shown by the sound of the pipes as it accelerates away from the unsuspecting "victim". In 1988 I was selling these cars and the car in question was one of the first ones that we got in at the dealership that 1st year of the new front-drivers. In my case the on the road cost shoud not exceed $4500. Hope this bit of info helps you in your quest to build a "sleeper cutlass supreme". By the way my car has only 7500 miles on it and is mostly still original-as-delivered.

uhmmmm...He said 97 cutlass supreme. not 87. the 97 cutlass supreme is front wheel drive, and has the 3.1 V6

Long story short, you typed alot for nothing, sebring

DEI37 04-06-2005 05:06 PM

Well, it's two years later, the engine is in the garage still, but kinda cleaned up, and maintanence stuff is done. I'm not going to undertake the swap myself, but rather have it done, as I just don't have the tools or time necessary to do it. It's getting done in May, and he's gonna take pics for me. I'll post some up as things progress. Not going to modify the engine much this time around. Going to install a 3.5" pulley on the blower, and call it good.

1990 Crown Vic LX can probably find one of these for like a grand easily.
Yank the stock 302 drop an EFI 351 Windsor in the sucker that's been stroked out to 419 cubes toss in a forged crank,connecting rods,forged dished low compression pistons.
Trickflow heads with a nice port and polish. Trickflow intake.
Yank the stock rear end bolt up an 8.8 inch rear with 31 spline Moser axles.
3:55 gears. Performance C6 tranny 2500 RPM stall convertor. Then turbo the sucker put down like 650 horsepower on daily driven boost. Redo the interior with new carpet, new head liner. New trim pieces. Toss in some new speakers a modern head unit. Lower it a bit get some old school steelies and some big tires paint the whole shooting match flat black.
Nobody would expect that old black Crown Vic that is bumping music so loudly would have enough power under the hood to burn all but the top contenders. That is until the tunes got turned down the cut outs got opened up and rattled their windows something horrible that is.

The more I think about the idea the more I want to try it. That would be SO much fun. You don't see too many people hooking up old late 80s early 90s Vics. I see people doing that same combo to Mustangs, Cougars,Thunderbirds hell even old trucks. But nobody every suspects that old Crown Vic.

The 86 Cutlass sounds like it'd be some fun. Personally, I'd stick a 427BB in it!

All of the aftermarket that you'd need for your v6/v8 SHO.

Both the V6 and the V8 were Yamaha, though I've never figured out why the V8 blew as much as it did.

I have been taking an intro mechanics class at the local community college. One of the mechanics there has a mid-eighties cutlass supreme with an LT-1 engine and I believe an early nineties trans am rear end. It does have a torsen differential, which he showed us when it was on the lift. I think (don't quote me) he said that with the 2.7 rear end gears it ran around low 14's.

A youngish guy, mid20's, who works the local speed shop has one of those older turbo Omni's. He's done other mods on it like suspension to hook up, fuel etc to make sure it doesn't blow up, plus larger turbo. I've seen his low 10 second time slips. The car still looks like a mundane Omni except he recently put nice wheels on it ...sticky rubber is required.

As a sleeper, I was also remembering that car that took part in the SCC Ultimate Street Car Challenge a year or two ago; it was a Hyundai 4 door sedan with an engine on both ends of the car, each engine driving the respective F/R wheels, moded to run on pure methanol; the guy only street races for money (my public safety comment delayed) and the thing is insanely fast, at least in the first 1/2 mile.

Did it on a bet like 4 or 5 years back in highschool. The Pontiac engine only fits with a complete rebuild. New frame, pushback the firewall, replace basically everything. The only thing that was SHO was the interrior, upper frame, some of the body, and the stupid driver.

1990 Ford Taurus SHO
Stock engine: Yamaha 3.0L V6 DOHC 24V FI Engine
Stock HP: 220
Problems: bad tranny, cooling system failing, other undiagnosed engine problems

bet: My buddy with a Mustang GT said that no matter what I did to my car, he could beat me. I had money and I was young.

I started by contacting several good mechanics locally who were into building unorthodox cars. One of them agreed to let me assist him, for a price. He had a 1968 Firebird 400" engine with part of the frame. We rediesigned the SHO's frame to match it with the stronger, heavier Potiac frame. Had a hell of a time with the bumper. We decided to counterbalance the heavy engine with a beefier exhauset, roghtly 3" straight pipes coming from stainless 4-1 headers. The steering and suspension had to also be adjusted for the weight. I'll let you know if I find pictures.

Just kidding of course. Who would put a V8 in a taurus? :crazy:

DEI37 04-07-2005 04:33 PM

Ford would. And did. It was a 3.4 Liter DOHC 4v V8, made 235HP if I remember right.

irseg 04-07-2005 05:22 PM

Damn, DEI37 beat me to it. Plus the Lincoln Continental is on the same platform as the Taurus, and has a DOHC 4.6 V8 putting out 260HP. It's detuned somewhat (puts out 280-300hp in other applications), most likely for torque steer and/or transaxle durability issues.

Now there's an idea--take a late 90's Taurus wagon, drop in a Continental drivetrain, beef up the tranny, and get the engine back up to the power output it has in other cars (intake/exhaust/chip most likely)..that'd be a heck of a sleeper!

cudaboy 04-10-2005 08:13 PM

hmm a good street sleeper.
Id go with a honda accord 4dr, back 1/2 it and fit some 275/50 street slicks on it. put reg 255/50's on the front the mod the front suspension to hold a 434 sbc. Who'd expect it. with some loud pipes and a bunch of decals everyone would think just another kid in a hopped up honda. Or just leave it in primer ;)

Lockjaw 04-11-2005 03:25 PM

lol nobody would mistake the can of angry bees that would usually come out of such a car for the low grumble of a SBC. You'd be seen coming a mile away. :)

NO2 + SR20DET Stage IV big turbo conversion (+500HP) w/ low restriction intercooler & exhaust, NISMO brakes, springs, trans & clutch attached to a dorky 1995 vintage Nissan Altima w/ beat paint, fart can muffler, stupid ironing board sized rear wing, NO2, Nitto & APC stickers everywhere, "xenon" headlight bulbs & the gaudiest 18" spinners I could find.

Heh, heh, heh............

No one expects a rice burner in the above external condition to actually be fast.

a near sleeper I drove (not mine) was a early '60s Austin Healey Sprite ( the bug eyed one) with a 327 chevy, 2 4 barrel holleys 3/4 race cam, rollers, custom headers, 4 speed trans, cut down positrack rear end. the only thing that gave it away were the carbs on the hood, and with a cover they were not obvious( unless you knew what a sprite should look like) the big problem with it was it shredded the right rear tire all the time ( torque would lift the left side of the car, not off the ground but enough)

and before someone asks I don't know how he got it in there, speculate ( well am certain) custom mounts and reworked body. If I remember right it would run in the neighborhood of 12 second quarters.

I saw and drove this in the early '70s once,left the country before I could find more out about it.

lecas 04-13-2005 06:32 PM

on another note, get a late 50s nash rambler, drop in as many cubes as you can replaceing all running gear at the same time. you'd have a big heavy UGLY but fast car

BadNick 04-14-2005 09:19 AM

I think it's in this month's HotRod magazine ...Jay Leno's "sleeper" Olds Toronado with a Lingenfelter twin turbo big block ...I think it was a bb not sb. Of course most of us don't have unlimited resources like he does but I thought it was cool anyway.

tspikes51 04-14-2005 09:25 PM

My fave sleeper was the 11 sec Escort. 5L Mustang engine, miata tranny with RWD conversion.

What makes the Cutlass ideal for this??? I have a '96. BTW, I thought you could get a special ed. of the car that had an L67 of the floor.

Danno 04-15-2005 10:00 AM

Cutlass rwd Conversion
 
I gave this some thought a while back. The w-body is not engineered for rwd, therefore the rear suspension is not very strong and as with most fwd cars there is not much of tranny tunnel. I've come up with a couple of ideas found surfing the net. These would give more room in the engine bay and better weight distribution.

1) Use a curved "rope drive" torque tube and rear transaxle from a 63 Pontiac Tempest like Jay did on his v-12 Corvair. See it at www.corvaircorsa.com/V-12-01.html . Very cool conversion. Don't know how I would hang the transaxle and suspension though.

2) Torque tube with manual transaxle and torsion tube suspension from a 944/928 Porsche. As with the 928, the 944 transaxle can also handle the power and torque of a v8. Found info at renegadehybrids.com they do v8 Porsche conversions.

The only thing stopping me from persuing this is time and money. :(

Back in 1987 a friend of mine wrecked a 71 challenger with a 383. We took the motor trans and rear end and stuffed it in a plymouth reliant K station wagon. We were young and stupid. We had no idea that you had to beef up the unibody to support the power. It only took 4 weeks to destroy it to the point it actually broke in half. We had jumped the car a few times prior to the engine swap so maybe it wasn't the best car to put the motor in but it was fun and faster than anything I have driven since. I wouldn't drive it that fast if I had the chance to now. Like I said we were young and dumb. It was one hell of a sleeper. The best part is that we were seen in the original car prior to the swap and it had crappy exhaust so no one thought twice until we stomped the gas.

I got that issue and I also watched them build that thing on Rides....man I would love a car with 1100+hp :lol:

I would use an old levin or such. Drop a spoon crate in.
