Is there a cam you would recommend that would get me that? Would I need to change my intake too. Since I will be pulling the engine to change pistons to increase my compression it would be an ideal time to change a few other things. Would the performer RPM a better manifold for me? Currently I'm running a Turbo 350 and 3:08 gears in the rear. I do plan on changing the rear end gears to either 3.55 or 3.73 and eventually a M21 4 speed.
