Re: 1972 307 cam selection... HELP!
A bigger cam will reduce torque at low RPMs. Exactly what you don't want! Bigger cams need better heads and higher compression, and even then, all you're gonna do is make more power at higher RPMs.
Your best path to more torque in 4th gear would be a 3.42 or 3.73 axle. Of course you could skip that and install a near-stock 350, which would get you lots more torque at all RPMs, with little to no decrease in gas mileage.
