3.90 YES or NO?

I agree with POS Dakota. Non-OD and low gear makes for a lousy street car.

Hell, even with the 3.91 it gets old spinning it to 2800 at 40-ish.

I put 3.55 in the Chally (which has a 318), and that's plenty for a cruiser. A 318 is only gonna have so much umph anyway.

I think a converter would help the car more than the gear with fewer side effects.
