Ok I recently picked up a 1985 Trans Am, and it's in very good condition, but I'm changing out the original 305ci V8 for a 350ci V8. I'm curious as to what kind of camshaft I should run in the vehicle. Is there a cam out there that will give me around 300-320 Rear wheel HP and still work properly with the factory Tuned Port Injection? The engine I have here has been completely overhauled, and it runs cylinder heads with approximately 165CC intake runners, and 58CC combustion chamber size, netting me somewhere in the area of 9.7-10.0:1 compression ratio. I was looking at a camshaft with a duration of about 224/234 degrees duration, and .465"/.488" lift, intake/exhaust respectively, but I fear that the loss of vacuum will not bode well with the ECM. I really really really do not want to switch to a carburetor. Sooooo, if anyone could give me some advice, I would appreciate it. Thanks!
