The torque convertor on the 700 is different between gas and diesel. Most diesel convertors have a six bolt flange, while most gassers use only three bolts. The diesels have a lower stall speed than the gassers. The governors in the transmission are also different.

Now, that being said, the diesel tranny will still bolt right up to any small-block, and you can still use the diesel convertor. However, you will probably find that the tranny won't shift right. You can easily swap out the governor later, though, if you'd like.

The 6.2L and Chevy gas small-blocks share the same motor mounts.

You will need all accessories though, like alternator, PS pump, a/c brackets, etc.

My suggestion is to fix the 6.2L, and you will have a dependable, powerful, full-size tank that gets 20 + mpg.
