[IROC383]

Hey guys,
Im in the process of tackling the rear end for a future AI camaro. I've seen different set ups for different applications.
I currently have 85 Iroc with 7 5/8 stock 3.73, with Power Traxx posi. I carry ZR1 11" on back with spacers. Id like to beef up rear, add disc brakes and set up proportioning valve. Which option would be best for least money. Chattanooga, TN.

Ford 9". Any stock rearend, even freshened, is on borrowed time at AI power levels in my opinion.

I disagree. You bought 2nd hand rear ends that probably had garbage set-ups with aftermarket gears, and didn't you have a clutch issue at the time?

Randy M. was putting 500 HP through a 10 bolt with a 3.91, I think a GM 3.42 / 3.73 with a good set up can last a long time with <350 HP. Maybe not forever, but a long time.

I was putting approximately 460 to the rear wheels with the "stock" rear. At that level, it would break once a year like clockwork. Of course I was using 3:90 gears...which, I believe are thinner cut like a 4:10, and 9 times out of 10 only the ring and pinion was bad. I lost one T2R in 6 years as well.
