The 77 may have an 8.5" Diff. The 82 has a 7.5".

Codes to check for Ratio needed/wanted.

When you say "just swap the gears" I can't help but think that you don't realize what your in for. You'd be money ahead to buy new gears, ring and pinion sets cam be kind of like flat tappet cams they develop wear patterns and may not respond well to change. It would be far easier to swap in a complete rearend with a better ratio. Every street stock racer in the country has one in the weeds behind his garage.

Most 3rd gen Camaros and S10s used the 7.5" axle. Gears and posi units are cheap and easy. Of course, installing it properly requires skill and proper tools. Don't expect miracles from the 307. You'd be money ahead by bolting in an Olds 455.
