Red, it's a 1968 low compression 400 with a 4bbl Carter AFB "Competition Series" carb built by Weber. Runs on 97 oct and just as well on Regular 'ol 87 . Runs best on gas with no ethanol. If I can get it, I like to run 100LL thru it and clean it out. Lately I'm adding a few gallons of VP C9/96oct racing fuel to whatever is in the tank. Runs even better with it. The engine is pushing 400 hp.
Schroeder, mileage depends on your foot and the gearing in the rear. I'm running a 3:55 gear set and at 70 mph it's pushing 3300 rpm. Not very good for mileage. I'm planning on going to a 3:36 grear set that will lower the rpms. 255/60 15s re on the back end that helped lower the engin3 rpms by 300 too. And back in 1970 with my first 66 GTO gas was only 32 cents a gallon. So yeah, we didn't car about gas mileage. LOL
