I did that about 10 years ago with my 5.0L. It was great until one burnout cost me ~$600. The spring perches broke from the axle so the axle spun up into the floor board. Blew my 2 week old custom drive shaft into 20 pieces, bent the pinion, dented the floor of my tub, all kinds of fun stuff. Thank god I had a locker in the front so I could drive it home.
Today I fully reassembled and sealed my Dana 300.
Man, that was a costly burnout
Yeah, swapping that 302 in was the best mod to do, rather than fixing the tired out inline six
