Pump Gas or Race Gas?
I would like to find out if a 347 motor running 11.2 compression would run pump gas, race gas, or a mixture. Would premium gas with a can of octane booster do the job, or would a mixture of racing fuel and premium work? What is a good resource to use concerning engine compression and fuel requirements?
Any help is greatly appreciated! Thanks! MrBB |

Depends on the heads, cam, timing, ect.

My best friend runs a 351w at 11.2 on pump gas, timing is turned down a bit, but that thing has tons of torque down low. Hell, I could not help but spin the tires when I was driving it.
