how high of comression can be ran on pump gas
i am building a 347 engine and have the trex cam. The trex cam loves compression according to thunder racing. what is the safest compression i can run with that cam and spray on a good tune on pump gas? 11:1, 11:5?

pump gas is a VERY relative term, esp with the new blends being used as substitutes for the real thing in most gas pumps. basically it is all in the tuning/timing/setup. some engines like more cr, some dont.
