I did'nt ask him about the needles. Phil said in order to get the correct squish you must do both sides of the piston at once. So I did and got a reading of .058-.059. He also said that I want it to be right around .055. So it is close.My guess is with the bigger bore you have to open up the squish more. I did mention to him that I would like for him to build me a set of pipes and dyno it sometime in the fall. He told me that I should see mid 250's with that motor, so I am down on hp of what it is capable of. He did tell me to put the fuel to it down low.
