360 driver build

Screw gear vendors. A regular A-500 will do great.

In addition to what moper was saying. In my 1st Dodge Magnum I had a 360 that got 20 mpg's. Stock engine with a factory 4bbl. intake and a Carter 625, dual exhaust off the manifolds, it also had twin cats, needed for the time, (dang laws!) A 340 trap door air cleaner w/K&N filter. An MSD fired it all off on a stock junk yard distributor.

the rear gears were 2.76's w/235/60/15's on all 4 corners. The car weighed in @ 3700 since it was loaded with everything except a moon roof. Carpet in the trunk even.
