let me just clarify my goal a little more. for me, it is not really about the highest horsepower numbers. as we have seen with smaller cube motors, it may have a higher horsepower number on the dyno, but still be not as fast (or less fun to drive) because the torque isn't there until the rpms are way up there. for me, it is all about the torque curve in the rpm range that i drive 95% of the time ... when i'm cruising at 2500 rpms in 2nd or 3rd gear, i want to be pushed back in my seat when i step on it. i want to feel the power from 3000-4500 rpms. so i am going for a high flat torque curve. max power at 6000 rpm is meaningless to me. so i guess what i am saying is that i will be very happy if my torque curve is around 450 at the wheels from 3000-4500 450 tq at 3000 rpm = 257 hp 450 tq at 4500 rpm = 385 hp 400 tq at 5252 rpm = 400 hp i would have every reason in the world to be happy with that.
