I know the 318 isn't regarded as a performance engine, but that's what I've got lying around right now. I also have a set of closed chamber w2 heads with 2.02 valves. The chambers are 57cc and the ports are stock. I have all the valvetrain, and the intake manifold. With thin head gaskets it should be about 9.7-1. My question is, what is a good cam for this in a 2800 lb Dart bracket car with 4.10 gears and a 3000 stall converter?
