Get a lower comp piston. I dont know that they make a 11:1 for the BB though.Orlando so what should I do ??? To run pump gas ???
Someone other than me can anwser this better for you. I asked the same question as you when I was a stock bore running 12:1 and people I trust said it wouldnt be safe.Why do I see these 450 on a 12.??? Piston on pump gas
No need with stock compression ratio , too much octane is slowing combustion with low compression engineoff topic, but would it help or hurt anything to run ~100 octane in a motor with stock internals? If its that much better than "premium" pump gas i may start to look around for some out here.
