well....its a SOHC. and i calculated everything...bore..piston..etc... the calculator said the compression would be 12.5:1 im thinking now WOW!!!!!! great for a D series.... wondering if u guys think that would be too much??? if so...wat would the gas have to be runing??i heard it should run 93-95octane.....i cant find places with that much octane..so should i reduce the compression??? or would i be fine with 76 PLUS gas(91octane) thanks i really need the info.
