Basically I want to extend the power band and Rev to 8500 safely. We're going solid lifters for this, arrow crank and Carrillo long rods. I have a set of 9.5:1 pistons but won't run that high as id have to use race fuel all the time.
Idea is to have usable power from 3300-3400- 7700ish whether that will actually happen or not is debatable.

Sorry for thread highjack

I went wet liner as the peak cylinder pressures we were aiming for are high (bringing boost in early). My block would have been borderline at +1mm.
