Ok first off I got an 87 Iroc that I just built a wild 383 for. Educated guess would be give or take 600 horse with the AFR heads and super light rotating assembly (better be that light for $2000 right) etc etc... Anyway I got A TCI race trans that will hold up to the application. Only thing left is the rear... What do you guys recommend? I don't really know if it is possible to beef up the stock rear with all new parts, axles etc. so I was thinkin bout 9" but didn't know how much of a pain it is to swap out different style rears... any comments would be great on either route.
