Heads and cam
take a look at this before you do any thing the set up put my car at 400rwhp
Don't be afraid to keep the cam mild, IMO the 306 would be a downright mistake, the 305 would be the better choice but I would instead encourage you too look at the GMPP 846 it is 222 on the intake, don't know the rest of the specs off the top of my head but it is a good cam that makes nice power in a usable range. It should be used a whole lot more often than it is.
