I have had every machinest tell me that I can't do high compression anymore because pump gas is so bad. I don't understand that because everywhere I go there are very radical rod's and they all seem to be running on pump gas. If they arn't, what are they using? In other words, what is everyone using that have giant cam stroker motors with 500 hp? Guys I need help, I have a good friend that is building a big mopar and I just can't let him walk on me!!! HELP!!!Enlighten me Guru's!! Is it really true??
