Poll: What's your favorite target compression ratio for boost or N.A.?
I asked this question on the Gen. 3 forum as well, but here the chamber options are a little wider. 60cc, 65cc, 70cc all being pretty common.
The question is: If you could pick one ratio for boost and another for N.A. (plus a light hit of spray maybe) on your street/strip vehicle, what would it be? 9.0, 9.5, 11, 11.5?

60cc or 65cc for N.A. all depending on pistons used with around 11.5, I'd be will to go higher if a larger cam is used. Or 11.0 with a smaller cam to keep down cylinder pressure.
For F.I. 70cc it's open as it's boost dependant if less boost more compression 9.0 to 9.5 with a little meth and cooler to keep from detonation. Factory GM cars with FI such as Edelbrock S/C come in with factory 11.0 compression yet less boost.
