I have noticed that you keep coming back to your compression ratio. As long as you use the right fuels it should never be a concern. I run 12.4 C/R so far only a 150 horse shot, but everything is geared to run 250 HP (If it will hook). As long as I have the right fuel, VP C16 in this case, I have no worries. C/R should not be calculated into the size of the shot. I would look at the cam...wider LSA, and a a bit more duration on the exhaust.
