Race gas vs. Methanol vs. Ethanol
We have almost finished our new SBC, it is 12.5 to 1 compression, Brodix alum heads, Herbert roller cam 0.6 lift. It has a 3500 stall, TH 350 with 4.11 gears. Car is about 3200 lbs.
One thing we don't have yet is a new carb. I plan to install a whole new fuel system, tank to carb. Some guys at our local track says I should run methanol instead of race gas, easier to get a little cheaper.
I was also thinking Ethanol. Anyone know the differences in using these three fuels? I don't see many running Ethanol, but I do hear of it.
thanks for your help.
