when is dynamic CR too low?
I was using this cool program that tells me dynamic and static compression ratios after i type in a million things about the engine it seems, so it seems pretty accurate. I am getting a 6.9:1 dynamic CR, and a 8.8:1 Static CR. Is this too low for a 15 or even 20psi setup?
Should I go smaller cam ? 230/236 duration @.050" or smaller cylinder head chambers? This is with 75cc chambers, I can do 65cc.

Call Comp cams (or whoever your cam manufacturer is) and ask them to recommend/grind you a blower cam. My guess is it will be a bit smaller than what you are looking at.
