Compression ratio with PI heads
I plan to do the PI head swap soon and was thinking 10.4-1 might be a bit to high and hard on the bottom end. I was thinking of haveing some material machined out of the bowls to lower the ratio or is the engine up to it. I plan on 24 lbs injectors bigger fuel pump headers MAF new intake manifold. So what MAF and should I go for the Bullit intake or the stock 99 GTone?
