Ok guys first post here so lets see how it goes. Just recently purchased a '67 Camaro with a 355 stroker motor with 12:1 comp. Basically i just want to understand the term "stroker" and I know 12:1 is way to much comp to hold any kind of Forced Induction but what about nitrous? ALso would a simple piston swap for something with a substantially lower Comp ratio, could it hold boost then? Any other things I can do to get more power out of it? IT seems to have a the whole nine yards. Also I have heard of Weiland but could someone tell me who Weiand is>? That is the stamp on the intake manifold. Basically, the car is awesome but i want more power and would like to go down the F.I. road. anything i can do with this motor to make it worthy or would i be better off selling it and starting fresh. PLEASE, leave as much detail as you can. THANKS TO EVERYONE. hopefully my experience here will be as good as all the times I have used Honda-tech.com for my Rice Burner passion! If i didnt explain anything right lemme know and i will do what i can to fix. I WANT A BLOWER!!!!!!

EM,

First off, a "355" is a 350 Chevy bored .030" oversize. It is not a "stroker". A stroker is an engine that has had the displacement increased by lengthening the stroke. The ONLY way to lengthen the stroke is to change the crankshaft.

12:1 is a popular number "thrown around". It is certainly too high for 93 octane gas (a must for a street-driven car). It's also too high for all but the smallest blowers, unless methynol is the fuel. We keep static compression under 9:1 for engines with REAL blowers.

You need to supply more detail. What are the head castings? (brand, chamber volume, valve and runner size) Any idea the cam specs?

Weiand (say "why-and") is an aftermarket company making intake manifolds and other "bolt on" performance parts. Regarding them, the old saying "You get what you pay for" applies. They are okay, but their technology has lagged behind the "leading" maker (Edelbrock). They ARE less expensive...
