im at 11.0:1 CR and I need to know if i can use 93 octane pump gas or do I have to go higher? Diff ppl have said i need to go higher cause it can blow my motor. The Motor has Forged PRW Pop up Pistons, Steel Crank and factory Heads. I want to get a Performer RPM Intake and a Comp Cam .575 Lift. Any info would be great!!
