Is an 8.2 fairly stout? It is in good condition w/a posi? Would it be tough enough for a heavy street car with mid 400 horsies, an auto, and fairly good tires? Thanx.
Isn't there a member here that has been racing for years on the same 8.2? Are there any secrets to keeping it alive? Or if you have one, just run it and keep an eye open for a 12 bolt or an 8.5? Thanx.
The secret to keep it alive is don't use it. :grin: I have broken a few of them, one twisted the pinion in half, many broken spider gears and twisted many axles. You cant beat an 8.5 rear, they are cheap and tough.
the trick to making an 8.2 live is no 4 speed. no nitrous out of the hole..no smioking the tires around corners..the last one is to preserve the posi carrier. i ran a 8.2 in a 4000 lb car with slicks with no problems.. pulled consistent 1.7 60' times and in the low low twelve second range. made a few nitrous assisted passes deep into the elevens and even made one pass were i hit it right out of the hole. no problems.. had a 70 FS455 with a 4 speed and slicks.. one 3500 rpm and dump the clutch and i snapped an axle..

Most 8.2's are weak & will not handle 450 ft/lbs of torque. Strongest of the 8.2 10 bolts were Pontiac's optional HD Safe-T-Track 8.2 rear, followed by the '68-70 Buick 8.2's. Both of these 8.2's are expensive to build, & best left for high point restorations. Either an 8.5 A-body or an upgraded 12 bolt is usually the best alternative. :3gears: Roger
