Posi Rear end

How do you ID a generation 3 camaro rear end out of a '87 Camaro with 3.23 gears. Numbers on the pumpkin are GM N 225226/6

 

Just by looking at it I think is a 7.5" are these good can they handle a 350-400hp engine

 

they are not that strong...

 

I have a good chance of blowing it out with a 401 nailhead and heavy foot

 

yup...

 

I believe they are "limited slip" rears.

 

So now I am looking for a 10 bolt 8.5" out of a camaro anything else that came with these?

 

what kind of car are you putting it in?

 

there were 8.5 inch rear ends in 7r2 s10s posi

 

if its going in a early chevy 70"scamaro/firebird and nova will work

 

its gonna go in my '50 chevy 3100

 

Run it till it breaks then put a real rearend in it..I think the rear ends are good for 300 real hp. If you hook up, its a gonner..

 

Thanks Dave, I feel with a 401 Nailhead theres gonna be a lot of hooking up being had.

 

Someone recommended using a ford 8.8"

 

All my fords (3) have the 8.8 with the same 3.55 gear set. Next best thing to a 9 inch!!

 

Damn if I go with 8.8 I am gonna have to exchange my front rotors as they are 4.75 bolt pattern. This is something I am gonna have to think about.

 

Is there a kit that you can buy to change the 4.5" bolt pattern on Ford 8.8" to a Chevy 4.75" Chevy bolt pattern?

 

Impalas chevelles biscains come to mind.

Even the bigger 10 bolt is not really a high zoot rear. I would look for a 12 bolt unless your car is pretty light.

 

its only a truck

 

need to know the rear axle width in your truck now, from axle flange to axle flange, backing plate measurement doesnt mean **** cause the brake offset is different.

8.5 are very good.some time back a read that a guy was swapping ford and chevy axles in rear ends.He would match the spine and length.Not sure about bearings

 

A carefully ***embled 10 bolt 8.5 inch will handle drag slicks and 500 hp.A 12 bolt is a little stronger and a lot more expensive to buy as an ***embly.....
