stroker 318

Are you talking about a 390 cube motor?

IMO, considering the size of the engine, I would be looking at a set of Edelbrock heads with the bowl area ported. The head is about sized right for the popular 360 engine. I think it needs just a little help for the extra cubes.

I don't muc of the RHS head.

What cam and C-ratio? What is the build for? Power wise, your looking for what?
