Cam Swap
Hey everyone,
I bought another 86 Vette coupe, it is white with saddle leather interior.
When the weather warms up here in NJ I am planning on changing some parts out for performance. I have bought long tube headers and am deleting the cats, the one under the car will be replaced with a 2 1/2 inch X pipe back to Corsa mufflers, polished and ported upper and lower intake manifolds, AFR 195 heads with 64 Cc combustion chambers, BBK 58mm throttle body, Lunati Voodoo camshaft 218/224, New timing chain and gear set, EGR block off plate.
The bottom end is already .030 over making it a 355, what kind of HP / TQ numbers do we estimate it should make? Is there anyone that has done all of this work?
Thank you, I appreciate your input

If you're going to run a TPI, long runner system you're going to need to have an aftermarket base extrude honed ($400 for the honing and $450 for the base) and run AZ Speed and Marine large tube runners ($545), or just step up to a FIRST Fuel Injection "TPI" intake (around $1,350 with throttle body and the fuel lines needed). If not, you're going to go down the same road so many have gone down before you by choking the ever living crap out of those heads and ending up extremely disappointed in how it runs.
If your budget can't cover the Eliminators and a better TPI induction, you would be better off buying the Enforcers and a set of AZ Speed and Marine runners for your ported base intake.

I don't think the TPI intake will allow for much more than that. Even "ported and polished". You can't really port the runners at all, they're so thin...you can port the base. IDK...maybe it'll do better than that, but I say 300 crank or about 270 wheel. Do it and show us!
