I had a 360 with 205 PSI cranking pressure that would run on 93 pump gas. It protested if I really poured the coals to it without a few gallons of 114. I'm sure I could have tuned it better but never took the time.
i beleive that , had a 340 with 195 psi ran okay on 93 unles it was lugging up a hill in 2nd gear a few gallons of 112 sue woke it up . but 240 **** that is high did they use methanol injection to run on pump gas ?
