Kind of new at this, so trying many things, and many things fail, but its fun anyway. The information I am getting from here is amazing, and great insight.
I have 87 Monte Carlo SS, stock 10 bolt 3.73. The stall is 1700 for the 700r4, and considering going higher. I would guess the 383 stroker puts out 400 hp.. (not tested, someone else built the motor). I am actually a bit disappointed in the launch. I figure this would be a great start for something better? I am considering swapping old rear for a 2002 Camaro rear end, Posi 3.73 gears.
Any input would appreciated.. Not even sure if I am in the right place Thanks

 

The F-body rear axle is not a direct swap due to the different suspension designs. While both are "10 bolt" axles they are completely different, and the F-car axle has a smaller ring gear and is inherently weaker than your G-Body 10 bolt. HTH

 

Yeah, the G-body 10-bolt is MUCH stronger than the F-body 10-bolt. I wouldn't consider swapping an F-body rear into a G-body, ever.

 

I wish the pictures or any of the links still worked... I cant see anything!

 

G body had both 7.5" and 8.5" rears, as did the B body.

 

Good point; his G-body is a Monte SS, which I believe got the 8.5".

 

Gomonty, the rear in your Monte Carlo is not weaker than an F-body rear nor is it stronger. They are the same rear internally. They differ in width and mounting, but the same 7.5 ring gear, etc. You need an 8.5 rear, which came in the Turbo Buick and the Hurst Olds. They will bolt in to your car. It would be the simplest solution.

 

love the easy upgrade. great mod for the money
found this for a nice tie in on the thread

Looks like to me if you could run the ends to a existing bracket it would be completely bolt on.

what carrier did you use? 2 or 3 . if you use the series 2 carrier you get thicker gears

 

i have a 10 bolt with lpw cover and arp 4 bolt main caps/welded brace kit. have been spraying 250 shot out of the hole for over a year no problem will be going to a 300 shot later this year.

 

will oem gears workwhen rebuilding the rear end with all of the good part to beaf it up?

 

He answered your questions in the first post... from 8 years ago. He isn't likely to respond to your questions since he hasn't been active on this site for more than 4 years.

Richmond gears tend to be noisy. Motives are good, and essentially oem.

 

so he used the 2 series with the heaver gear, has anyone done it with the 3 series and have the same results as the 2 series?
