nope, the older ones (1981 and older) i believe had 8.2s which is very comparable to an 8.5. but 1982-2002 were all 7.5s. i have a customer with a 2001 SLP camaro that we put a wild drivetrain in that still has the 7.5. hasn't broken it yet, altough it doesn't get launched too hard. car has a built stock displacement LS6 with a procharger D1-SC at 15 lbs of boost. makes 740 hp to the tires on pump gas/methanol injection on et street radials with a 6 speed and still hasnt broken the 7.5 yet. im sure it won't last forever, but i guess if you don't abuse it, it'll hold up better than most would expect. proved me way wrong, I told him that it might break even on a highway pull.
Last year of the 8.2 was like 1970 you will find 8.5s in 2nd gen fbodys 1982-1985 had the 7.5 but were weak so they got the 7.625 or whatever and I've heard rumors of a borg warner 9 bolt rear end that was put into the iroc Z's and from google research I see this is true... But yes 7.5s can handle power well if taken care of and have proper upgrades!
thanks for the info, cleared that up for me, wasn't sure when the 8.2's were retired!
