383 Stoker
Hello, My name is Chuck. I have a 1995 vette. I had a 1992 camaro L98
it was a 350 11.8.1 with a Paxton supercharger that made 10 lbs of boost. It ran 123.00mph, 12.0 had a hard time getting off the line. Well getting to the point. I am trying to use the same idea but in a vette. I bought a blower works charger and most of my engine parts forged pistons,crank,and rod For a 383. flat top pistons with Afr 210 heads which would give me 11.0.1 compression plus a vortech charger 8 lbs of boost. So dose anyone have any input?
Thanks, Chuck

I ran this Engine for 2 years. I ran stock cast pistons. to change the short block I would have had to replace everything. So I ran it to the end. And when it went, it went. I used tuner cats programing. The piston shattered into a billion Pieces. my new set up I plan on 11:1. I have SRP pistons, 4340 rod and crank. Go fast or go home.

Why not just run dished pistons and drop the compression to 9:1 and then turn up the boost to 15 or so. That will give you WAY more horsepower than the compression increase of two points and be much safer.

I have 10.8:1 and was running 6 boost(procharger) through an intercooler and didn't last long. Less than a year! Destroyed the gasket and melted the head between cylinder 3 and 5. That high comp. I would def. not tell anyone to do this. Get N20 and use it when you want it!!

If you are at High Altitude you could easily get away with it. I don't know the physics involved but up here you can high compression and decent boost. krivera on here had a 383 with 10.x and was running 12lbs of boost out of a procharger D-1 and he never had any problems except for traction problems

I would not have any piston other than forged, especially when your under boost. I bought into the benefits of Hyperyou@@ck me pistons. I could have spent a few dollars more and got forged. Won't make that mistake again.
