Any body know the easiest way to swap the rear end/gears from a 68 convertible that has 3.08 gears? I have scrapped the old 307 motor and am looking for a bigger powerplant as well as changing the gearing.
Any help is appreciated!!!! Thanks.

The EASIEST way is to pay a pro to do it.

You didn't say what housing you have, but I believe if you have stock 3.08 gears in a 8.5 10 bolt, or any 12 bolt housing, you can upgrade anywhere between 2.73 and 4.88 ratios without changing carriers.

As far as engine suggestions... how fast do you want to spend?
