i have a 1984 camaro.........how much TQ can the STOCK 10 bolt rear take?? I'm also interested in how much Tq you guys have put through them "stock"...what kind of abuse have you guys given these? ......im gonna do a v8 swap..and i am trying to figure out what kinda of power i can make without having to Beef up the rear...or replace it

Thanks
John

 

421 ft/lbs is the limit

 

lol....your kidding me right??....i know its not a exact number.........im sure there are alot of people on here who have modified there cars....what kind of torque are you guys putting out with the stock rear?

 

no, 421ft/lbs is the published spec; really.

 

WOW...i was told that the V6 and V8 camaro's rear end was the same design.......so that would apply to my V6 camaro right??
Thanks alot
John

 

As far as we know; 421 is exactly where they all spontaneously disintegrate.

 

ok i dont beleive that...as soon as you reach 421 ft/pnds of torque it dont instantly explode in a cloud of white smoke....
419,420,421 BOOM! nope it wont work like that....where are you finding this info??...maybe im wrong though

 

What they're trying to say facetiously is that there is no answer.

 

I have a 10-bolt in my 4x4 s10 that's got a 350 putting down about 400 ft. lbs. ..... and it broke. Now, granted I do beat the snot out of it, and 31" tires don't help either. Didn't snap axles or anything, just that stupid pin came loose and smacked the pinion. This will cause pieces. - But, the guy who did the trans put in an Eaton diff, and he swears it will hold up now.

 

I've seen cars run low 10's and live for a while on a 10 bolt. Personally I would be afraid to be in a car with that power and a 10 bolt while beating on it. Seen others run high 14's and blow up. Depends on how you drive it + the amount of power.

 

Why do people ask questions like this??

Every single carrier will be different due to differences in metal composition, factory defects and how its been driven for the last 20 years.

It could break at 100lb or 800lb...

 

i know every rear end is different........and im not needing a exact number cause i know there aint one.....i was told once that they cant hold over 200 ft/lbs...which im pretty sure aint true......i just want to know how much power have you guys put through these succesfully in their stock form......
i must say that this is the first time iv'e been to this board...im rather dissapointed...mostly im working on collecting peices for the 2.8 to the 5.7 swap......i wanna know how much power i can make without having to worry about breaking stuff...around 300 ft/lbs? 350 ft/lbs?
John

 

Like i said it could break at 100 or 800lbs bud.

Most people with anything more than a spicey 350 bust them up but that again their are some people running blown 383s and have driven around on the same 10bolt for years...

Theirs just so much that can come into play when trying to answer a question like this.


I would say my current 350 is putting something like 350lbs through my stock 84 10 bolt and i beat on it pretty hard with no problems yet. Then their are people on here with V6s that have blown a 10bolt.

 

without you guys being a ***...what i was looking for was....if you modified your engine...tell me Approximate what kinda of TQ you have and what problems you have with the rear end......fatdog87..said what i was looking for......

 

There really isn't an answer like you're looking for. It might hold up for quite some time to a 500 rwhp street driven car with an automatic, or it could die on the first launch at the track with 250 HP with slicks and a manual.

 

yes their is an answer like im looking for.im wanting to know about YOUR car!......example: hi i have a 1986 camaro with a 5.7 and i have put down 3 ft/lbs succesfully..or not.....thats what im wanting

 

How were we being asses?

Were telling it like it is...

If i blow the rear in one of my 84s after bagging it for 3 years 300,000km and decide to throw the 10bolt out of my other 84 70,000km into it i might not even make it a block down the street without it blowing.

 

maybe im being a *** lol..........maybe i should explain more
its not going to see strip duty...no huge fire burnouts....
just daily driving, mostly everyday anyway
im wanting to put a 5.7 in there....stock if thats what it wants......i know its not gm's strongest rear end......and i know everyone is different......iv'e been told to just drop a v8 and romp on it and see if it holds up.....i cant do that..im not made of money...
the only real questions are
if your rear end is stock
what kind of power are you putting out..even if you broke your rear...what kind of abuse are you giving it? burnouts? old lady driving??

With an auto its alot more likely to hold up over a manual tranny ans the auto will give it a bit of cushoning.

As long as your not going out goofing off with a 400HP motor it should last you quite a while. Like i said with my 350 beating on my 10bolt for the last couple years i havent had a problem yet (knock on wood)

Your buddy is pretty much right though, all you can do is drive it and see what happens. Who knows your rear might outlast every other part on the car.

 

thankyou.. i have a auto...and i am gonna modify the rear but until then i dont wanna send the rear out to pasture....
and i apologise for snapping on you guys....i still need your help ..i cant burn my bridges yet
but the original question still applies

 

well i personally seen 87 TA go 10.09 at 133 on slicks behind a built 406 miniram and a 150shot spray on his 10 bolt rear

i think he has just new axles and posi. 10 bolts can be made decently strong

and why does everyone beat around the bush with nonsense? just answer the question

 

For what it's worth, both times I've blown one of these rears it was months after tell-tale noises and vibrations. The 10-bolt in my s10 was the factory offering with 160,000 miles on it. After the v8 swap it lasted for about another year. - But this gave me enough time to save up some funds for the new parts, so when the day came I was ready.

I'll go out on a limb here and say that if you drive conservatively, keep an eye on the lube levels and u-joints (bad vibrations can take their toll), and take it easy on the launches, you should get some more miles out of it. How much depends largely on what kind of condition it's in right now. Do you know this car's history? How was it driven/maintained?

Hopefully, when it starts to go south (it's not a question of if, but when) you'll be prepared, and it won't be a grenaded mess inside. The guy who built mine says that with a good set of gears and a decent diff., these things will hold up for most people. - Him & his son are geniuses, so I trust them.
