12 bolt vs 9"

[STOCKTON]

What is a 10 bolt rear end for a 68 camaro worth. What is better rear end a 12 bolt posi or a 9" . What is the downfall of putting in a ford 9" in a 68 camaro. I would like to hear who would do it and why and who would not.

Thanks

i'm not sure of what a 10 bolt is worth but as for the 12 bolt vs 9" I think it all depends on what your running in your car. For the High HP engine or with twin turbo's look'n for the drags the 9" is the stronger rear end but if your going to do a nice street/ cruise car I'd go with the 12 bolt. The 12 can handle plenty of power. I plan running my orig 12 bolt posi with a 500 hp 6speed combo in my 68 camaro. hope this helps........

I try to keep them 12 bolts unless my customers won't let me. A good 12 bolt can handle a lot of power. We put 900HP to a stock 12 bolt Camaro rear with a spool and a rear support. And that is dead hooking with low 1.30 short times.

12 bolts are more efficient due to pinion location, A 9" pinion is always trying to climb the ring gear, eating a little HP along the way. Is a 9" stronger then a 12 bolt? Yes! is a 12 bolt capable of handling what most mear mortals with throw at it, with a street car? Yes.

Then again, you can really confuse things and get one of the 9" centers that uses 12-bolt gears.

9" has bigger internals. The pinion shaft is pretty thick. All that thickness absorbs some horsepower to turn it.

The alloy 12bolt third member is only rated for a chassis weight of 3000lbs or less.
