I have a question about my rear end. It is a 7.5'" with a auburn pro diff 3.73 gears and after market axels. my question is how much can these little things really take? I have a 406 sb. with edelbrock rpm heads that makes in the neighborhood of 450+ horse. this year i hope to get it to the track. I would like to run slicks, but I'm not sure if i should. I would hate to gernade it after investing all that money into it. Should i sell it and buy a 12 bolt?

 

384 ft/lbs is the max a stock 10 bolt can handle

 

it will handle more with an auto tranny.

 

Is that the stock rear end, at the rear wheels or at the flywheel?

 

put a stud girdle cover on it if you haven't yet.

 

Hard to say but it definately wont be bullet proof with slicks and hard launches.

 

thanks for the help guys

 

slicks should come with a guarantee card when your using a 10bolt rear, if you dont break it with slicks somethings terribly wrong!

The auto does soften the blow a bit but a couple of dead hooks and it will be in the passenger seat with you...

 

How much help would a stud girdle be in terms of adding torque capacity to the rear end?
