Reply to "351C heads"

Power over what RPM?

between 2000 & 6000 rpm with stock exhaust manifolds...NADA.

However the 3V head has a higher port, requiring usage of a dedicated CHI intake, or a 2V intake with a CHI spacer, which raises the induction system 0.4". The CHI intake is quite high and your induction system will have to poke through the engine screen. It is a single plane intake and not as good a match with the cam I've recommended. The 3V heads, CHI intake, a hotter cam (3000 rpm to 7000 rpm)would make a good match, but better exhaust manifolds will be a must, or you're wasting your money. You would also be wasting your money to bolt these parts onto a short block with alot of miles on it. This combination has tremendous potential to make bhp, but not with a marginal ring seal and not without extensive cylinder block work. This combination would also stress the lower end of a high mileage engine to the point something will break.

The Edelbrock RPM air gap manifold will be tight as is, with a 0.4" spacer it may also require a hole in the engine screen, a lower manifold such as the Edelbrock performer will not be as good a match with the parts I've recommended, hence my recommendation. Make sense? Are you getting a feel for the "system" approach to building an engine.

The 2V heads will make a good foundation for you to use now, and make more power with later. Rebuild the engine, install a stroker crankshaft & a hydraulic roller cam and those heads will provide you upwards of 500 bhp. I think CHI advertises they'll support over 600 bhp. If you want to bolt up a wild induction system to them, a Parker 2V Funnel Web manifold would bolt right up. Trick Flow is supposed to be working on a fuel injection manifold for 2V heads.

Seems to me to be a good way to meet your needs now & in the future. Heck the more I write about it, the more I'm thinking I "need" a set of those heads.
