It's not necessarily that I WANT high RPM horsepower.....I'm kinda boxed in using the pistons I have which means I have about a 10.5 compression ratio, which will require a fairly large cam to run on pump gas. Coupled with the 4.11 gears and the T5 transmission I plan to swap in, it should still have some good grunt down low! The engine I have now loses very little on the bottom end now, even with 3.23 gears. I theorize that it's the long stroke of the 225 that helps out there.
