Re: 1972 307 cam selection... HELP!
I was averaging about 10.5-12 mpg with my 402 when i drove it almost daily a couple years ago with a TH400 and 3.73 gears on 255/70-15 tires. It had a mild cam, stock intake, Edelbrock carb, and manifolds with turbo mufflers, no tail pipes. I didn’t beat it though, drove it pretty mildly. I would agree with RV type cam for low and midrange power. And definitely headers and a 2.5” exhaust system.
