PostSubject: cylinder heads.   Thu Feb 26, 2009 11:42 pm

my cylinder heads were made with small valves (1.94" intake and 1.50" exhaust valve) and i was also reading up that they made these head with restrictive air flow passages for lower end torque? anyways, thats no good for racing and i want bigger valves! huge valves! so a friend of mine told me to get heads off a chevy van, they have big valves and are higher compression. any input on this?

Try to find a set of Edelbrock heads. You won't be disappointed.

Definitely Edelbrocks. Have you made a choice on pistons yet? Been a while for me, TRW Forged Piston Sets seem to be the choice I'd make. They come balanced.

TRW's seem to be the standard for performance engines.

I think if this were mine and I had the money... I would go with a Isky roller cam and lifters. Crane Cams makes a great RV cam for the 350 that, from what I've heard, when idling and someone wants to race you, they think twice because of the sound the engine makes. A nice set of street headers will enhance that sound too.

That sounds about right considering in an RV you would want the low end grunt to get the mass moving. Which in a street/strip application would be great because it will give you a better launch off the line.
