I am putting my 496 together and am ending up with 8.5:1, I was hoping for 9 or a little higher, as I want to run on pump gas.
My question is, what kind of power difference am I looking at to bump it a point. I realize that CR is a very basic ingredient and is only but one factor of many.
Here is what I am running:
496 (4.31x4.25)
Ported Dart Iron Eagle heads
Comp Cams XE274 (230/236 @ .050 and 110 lobe sep)
Dart Manifold
EMI Exhaust
Is taking the trouble to boost the compression a little worth it?
Thanks all.
