I was thinking, instead of going with the "More Displacement" theory, I would like to head in a different direction. Stick with a stock displacement 5.3L (0.010" over for clean-up) and strap a Kenne Bell 2.8L supercharger to it. Run 12-14 psi with a goal of about 650RWHP. Effective displacment of about 500ci.

Thoughts?
