It was an experimental engine from Oldsmobile back in the '60s. Oldsmobile put together a 455 V8 DOHC made from all aluminum. The engine code is OW43. There was pics of that engine in a thread here a while back...years ago, best as I can remember. A search revealed nothing, and Google hasn't offered up any pictures, either. So, I'm relying on you guys to help me out. Thanks in advance.

Aluminum 4 valve 455 Hemi (OW-43)

There was an experimental engine based on the W-43, coded OW-43. It was designed for road racing applications. It had the same basic configuration as the W-43, but the materials were different. The block was cast from Reynolds-356 alloy and fitted with pressed in dry steel cylinder liners for the forged 12.2 to 1 pistons. It used billet steel connecting rods and a machined forged steel crank.

The OW-43 was developed at the same time that Chevrolet released its all aluminum ZL-1 427 engine, but the Olds engine was far more advanced and exotic than the Chevrolet engine. It had a redline just under 8500 rpm, and put out 300 HP at 3000 rpm, and 600 HP at 6000 rpm. The top output recorded for this engine at the Lansing dyno facility was 700 REAL horsepower at 6800 rpm. Tests were run with both carburetion (four Weber 48-IDA two barrels) and injection (three-inch ram stacks), with injection showing the most potential over 6000 rpm.

I couldn't find any pictures either.

Yeah, pics are a bitch right now. I had found the text articles, but I know there is more info on that engine out there. We had pics on this board some time ago. Might have been TFP V.3 now that I think about it, though. I just have no clue where to start digging for pics, as finding the actual engine wouldn't be a much harder task to accomplish!!

Thanks, guys.

Did you notice it said that there was an article about it in the May 1971 Hot Rod magazine? Maybe you can find that issue. Actually I think you could get it on ebay now, it's one of the ones in this pic

I didn't find the magazine, but I did find an article on the Oldsmobile experimental engines. Should have that in there. So...I bought it!

Hope I'm not digging up old threads, but I found this thread while doing a google search on the infamous OW-43. Seems you guys are looking for some pics of it, and if you're still interested, I'd be happy to post some.

I hope I don't get in trouble for posting scans, but a copy of this book is very hard to find. However, if it is against the rules, feel free to delete/edit this post.

Very nice. I got a thing off of eBay on these engines. Different than these. I'll need to save these at a later date...thanks!
