Welcome Jeremy, Let's see some pics!

I'm in the process of doing the 12 bolt conversion on my 62 now. Found a used rear w/ 3:07 gear ratio. Used CaptainFab's axle perches, would highly recommend them to anyone who is doing the conversion.

As far as how that HO rear would hold up to the horsepower. My truck has a 383 stroker in it with a TH400. It stood the all the abuse my son could give it! To what Clyde65 says about being loud, at 55mph I'm taching 2800-3000 rpm's, with flowmaster 10's on it you can't hear yourself think.
