my friend and i are putting in a new engine in his car, its an lt1 out of a 96/97 camaro and i was wondering if the one tire fire rear end is good enough for this much power. i think the rear end has something like 3.42's out back but i could be wrong. if this rear end sucks, what should he put in there?

thanks

The 9 bolt Australian is the strongest 3rd gen rear. The G92 5 speed cars came with 3.45 ratio, while most of the others came with 3.27 or 2.77.

It will hold up to the power. Go to www.9bolt.com for more info.

 

The factory 10-bolt will hold up to 300 horse easily enough, but unless you stick a posi unit in there you'll never get traction. Let us know what year the car is and what car it is and we'll tell you the ratio you're most likely to have.

As far as 9-bolt rears go, they are definitely stronger than a 10-bolt, but they're more expensive to work on and it's hard to find one with a good ratio. (i.e. non-2.77) Unless it's going to be modded for some serious power in the future I'd stick with the 10-bolt.

 

i believe its an 88 camaro, if not 88 +/- 1 year... what i was told was, before i got my GN i had an elcamino with a 425/425 motor in it and everyone said with the 7.5" in there the second i hooked the rear would exploed , is it the same case with the camaro rear ends? or were the G bodies different?

thanks for the help...

cut up a camaro rearend housing after you make a jig of it and get a good old 9 inch, then weld the mounts on and make a bracket for the tourque arm

 

425hp is bad news for a 10-bolt. If you're gonna be putting out that kind of power I'd suggest a 12-bolt or a Ford 9-inch.

 

Wait....

what actually makes a rear stronger? what actually falls apart due to hi-po? i have no idea what the "carrier" or what affects what.

what rears came in what year 3rd gens? any links or info would be nice , thnx

 

I had a 9-bolt rear with 3.45 gears, the ring and pinion broke driving on the street at ~90,000 miles when the car ran high 14s never seen a 60' below 2.2x.

Stick with the stock 10-bolt, when it breaks get a posi and new 28 spline axles and AL rear cover, if that breaks get out the check book for a 12 bolt or 9 inch.

 

I am a little over 300RWHP and have a 10 bolt. I have a 700r4 trans with 373 gears. I have not had a problem with my 10 bolt as I preload the drivetrain when racing. I have cut a best 60 foot of 1.85. That is with LCA and PHB. If it is a stick shift then you get the shock factor from dumping the clutch and it will not hold up. Just my .02

 

The stock 10 bolt will be fine with a 300hp motor. In my own case, it has held up fine with a 5200 stall 8" conv and 4.56 gears.

 

You may want to read my article called "How to build a better 10-bolt". http://www.ws6transam.org/10bolt.html

Therre are currently list members on CZ28 that actively drag race their cars with 10 bolt rears, and they are reliably cutting 1.6 scond 60-foot times. There are a couple fourth-gen LS1 cars that have gone high-10's with their 10 bolts before seeing trouble.

Set one up properly and you can make it survive 400+ horsepower.

 

hard to find, but a good drop in rear with no mods i.e. coil overs,torque arm bracket, & disk calipers in proper locations unlike 81-prior rears was an over the counter GM offered DANA 44
center cection in a gm f-body setup rear. i salvaged one out of an 84 Z-28 HURST camaro w/ 4:09 gears which currently resides in my 88 GTA. years of abuse and it still refuses to die.

 

I'am pushing a little over 350hp and still using the factory 7.5 10 bolt...no problems so far, but as soon as i get enough deniro together , I plan on installing a Moser 12 bolt !

 

Yeah, I probably will end up with a Moser 12 bolt eventually as well. The new engine (which is close to being done) is estimated to be 460 to 480 horsepower at the crank, and just as many foot-pounds of torque. I don't know what it'll do to my Torsen & Moser equipped 10 bolt. I probably shouldn't try runnng any slicks at the strip though, until the new axle is installed in a few years. I'm thinking the car will E/T in the high 11's at 120 MPH on drag radials.

Once I can save for a 12-bolt though, I might try those Nitrous spraybars that are already mounted in the intake! The shortblock is built strong enough for 700 HP and the pistons / combustion chambers/valves are all ceramic thermal barrier coated.

I doubt my little 7.5 inch Richmond gearset was designed for that kind of abuse.

 

Given how much those D44's run now and the limited gear choices I wonder why anyone would actually choose the D44 over a similar total cost 12 bolt or 9" dif. The Dana's ring gear isn't that much bigger than the stock dif's. If you're going to upgrade, leave yourself more options by going with a rear with a very wide selection of gear sets and carriers.
