How hard/expensive is it to switch out gearing on an A-body?

Why put a Chevy trans in a mopar........ He has a 4 speed 340 car, not exactly found everywhere. And I'm guessing he likes the 833.

I agree!! A 4 speed car is GREAT!! I put a Chevy trans in my car because it was survivor and didn't want to "cut it up" to install a Mopar trans just to get overdrive.

Assuming you have a 8.75 rear, not that bad at all, you can get an assembled center section and swap it in an afternoon fairly quick. plus you could sell the 3.91 center as is and pay for the swap for a 3.23 center section. Youre looking at anywhere from 50 bucks on up to 4-5 hundred bucks for the center sections depending on casting number, sure grip or open and ratio.

I agree again!! If he can buy everything at the prices you quote it would be great but he'll be limited on gearing for his highway cruising. I get great gas mileage in town as well but "svevobandini" will surely make a decision that best suites his needs.
