Just curious what are some expected compression numbers to get with 10.5:1 pistons 12.5:1 pistons as well
I am seeing about 280-290 psi on what are suppost to be 10.5:1 pistons. I fear that they are in reality 12.5:1, and I am going to be investing in a lot of race fuel to get rid of some agravating detonation.
thanks!

You could run 11.5:1 on 93 with stock timing. 12.5:1 is possible on 93 pulling a few degrees of timing up top.
