I tried searching the forums but couldn't come up with the info I was looking for. I have an '82 Z28 that has a 350 bored .30 over and a 6-71 Weiand blower. I bought the car as it sits now. The guy I bought it from put all the money into the engine and tranny (turbo 400) but not a dime into the chassis or rear end. I plan on an 8 point bar and SFC's this winter. I also was looking at good rear ends for it, and was wondering if a 12 bolt GM would be strong enough? The engine is putting out around 600 hp. If a stock 12 bolt would be strong enough...here's the dumb question - how do I know which one would be compatible with my generation Camaro? The ones I see on ebay all came from early 70's Novas, El Caminos etc. Are these all a standard width? I don't know much about rear ends, so any info would be helpful!

Honestly, I'd just go with a Ford 9 inch, if you can afford to spend about $2000, it's probably the best thing you could get for the car, and there are kits available that will bolt right in, and since it's got a third member, changing gear ratios is alot easier than with a standard rear, which is especially usefull if you want to drag race it, but don't want to use the low gears all the time. Plus, there's probably a wider selection of gears for that rear than most any other I've seen. Summit Racing sells up to 7.33:1.

 

Oh my gawd!!!!! I am selling my RX-7 SCCA race car, and using the money to upgrade my Camaro. Can't afford to have both car hobbies right now! $2,000 is about what I planned on spending for a good rear, and yes I do plan to drag race it sometimes. Thanks for the info!

That's the rear and axles.

That's a complete third member assembly with 4.11 gears, already installed. Little higher than I thought originally, but still not a bad deal. You can get nodular iron gears in one of those for about $300 more.

 

Wow thanks man!

 

GM 12 bolt and a Ford 9" rear end are both comprable choices. Even a 10 bolt will hold that power.

Fluffy Tiger recomended the same summit parts. He's got the right Idea.

 

Personally, I'd go with the Ford, just for the fact that it uses a third member, and is much easier to service, since most of the work on the gears can be done on a bench, and those who want to drag occaisionally and drive every day can buy a second third member and keep two different gear ratios set up at all times, with a (relatively) small amount of work for the swap.

 

That sounds exactly what I intend to do! You think 4.11's for the track? I have 3.23's now and am NOT pleased with the snap off the line. It does get pretty good mileage though!

 

For the track, as long as you can get traction with 4.11's lol.

 

It's got 295/50/15's on the rear...hopefully that will be enough!
