Pump gas

[fork]

Hi there I was needing to know what you guys thought about if I could run pump gas in my stock port,head milled .030, +4 timing, fatties, with 160psi comp. motor. Thanks

You are right on the verge of needing higher octane fuel. Generally 155lbs static compression is what we use as a baseline for pump gas. Between your timing and compression I would probably run some kind of mix of racegas and pump-gas. You're not THAT high yet, so you can probably get away with a 1/4 race gas and 3/4 pump gas. If you have easy/cheap access to racegas I'd go ahead and do a 50/50 mix.

Thanks for the reply, I did some searching before I asked and found I was right on the line but I just wanted to make sure and do you think I would benefit adding alittle more timing on this motor.
