I already bolted on the heads, so I am not sure how to find out this one:
I have Probe's low comp 8.5:1 pistons from their street fighter kit. However, I think that is for a 61 or 64cc head. I have a 58cc Canfield head-how would this change it? Other variable are: 8548 pt.2 gasket, 347 engine. I know there is a long formula for computing this, can anyone give me a ballpark figure?
Thanks

By going to the smaller cc head it raised the compression ration. You are in the neighborhood of 9-9.5:1

I just talked to someone at Probe and they said that the 8.5:1 is figured with a 61cc head. So if mine is 58cc, wouldnt that make compression in the neighbourhood of 8.7 or 8.8:1?
