Been there, done that - BONE STOCK trans, driveshaft and 7.5" rear - no issues.

I've done an M62 (Pontiac Bonneville) and a Whipple on my '94. You can do whatever you want with thought, $ and time. Don't rush it, do it right. FMU's are a COMPLETE waste of time, money and effort. Do it right, and reflash the PCM with the proper size injector.
