Basically I'm putting in a 383, and am looking into rearends.

Want to try and keep the price down. I was offered a 9 bolt with 3.73 gears in it, posi for 450.

I will have a built 700r4 in it as well.

the engine will produce anywhere from 400 to about 500 hp I really don't know.

Can a 9 bolt handle this?

I won't be putting slicks on it or have a huge converter maybe between 2800-3000 stall.

 

The 9-bolt should be fine for your combination. The main thing that will kill any drivetrain component is traction. Power is secondary. Your 383 will rip the tires loose before it has a chance to apply enough shear torque to the rear to break anything.

That being said, if you consider even sticky street tires for the car you really should look into upgrading the rear. $450 will put you about 1/4 of the way towards a bolt in 12-bolt. Just something to consider.

 

that rear end will be fine,i have had a bit more power than that and was good for a few years,had a bearing lock up new bearings it was ready for combat again!!!!!!!!!

 

This question is mainly for a friend but.

How much can the 10 bolt I believe 7.58" handle?

Could it be made to handle the same amount of power?

He won't be haveing a huge stall either infact same as mine 2800-3000. Without slicks.

I was told if you get a good set of gears. get a T/A girdle and weld it solid it can make it alot stronger.

Is it true, can you make a 10 bolt handle around that aswell?

 

Yes, the modificatiosn listed will beef us a 10-bolt, but don't kid yourself. These rears break on stock cars with street tires all the time. The biggest weakness is the puny ring gear. Even when it is trussed up and uses new gears and stronger parts it's just a matter of time. Again traction is the big killer, but power seems to ruin these rears with no other help too. It isn't as inherently strong as a 9-bolt, and that's the biggest problem with the 10-bolt.
