If i wanted to build my engine, i would stick with the current stroke, Raise CR to 13:1 (wish we had E85 here), VAC stage 3 heads and rev it to 9,000 or even higher.

It does feel a tad mushy in the low end compared to stock. Losing throttle response in lower rpm's is a part of centrifugal supercharger character. Can't change that. But up top it's just great.
