Edit. Misread ur post. BTW why are u wanting to go to 10.1?

Stopsign32v · 12-09-2011, 07:35 PM

Because 8.5 sucks!

Any good forged flattop is what you need.

I did the same thing to a friends Cobra motor that is on E85, made it much happier.

Diamond Pistons are real good.

3cc will give you a stock Mach compression ratio which is around 10:1. Flat tops will be about 10.4:1.
