AFR heads, intake/cam?

Joe - He can grind a cam that will be friendly to both sides, but if you ground it for one, it would probably work fine for the other anyways.

Now, the best way to get the most power is to set it up for one or the other, but a N/A cam can work for a supercharged car, and a supercharged cam can work N/A, if need be...

I personally think you should go with the tfs track heat matches the 165 well and a xe268 270 or 274 comp cam it will work very well the only thing that makes a manifold to BIG is the runners are to short and you loose torque because it does not match the operating range of the cam. Also the holly systemmax manifold is very nice.
