Thinking about selling..need advice

I am guessing you have the 3.23 rear gears in that 69 Dart. The engine will wind pretty good at 70 mph freeway speeds, like 3000-3500 rpm plus.

Drop in a set of 2.94 rear gears and you will only be turning your engine at 2000 rpm at 70 mph freeway driving. With still plenty of power along the way to pass anyone you want. 360s are known for the great low end torque they have besides.

Love the 2.94 gears, pushing around a B body with a 260 hp 318 4bbl, great overall performance, cruising, and pass anybody you want when you want.

Then drop in the Vintage Air and you are good to go.

Cheers . . . Keep that Car !
