Yours Monte still has the 7.5 in it and you been beating up on it all these years? Wow Doug wow... Thats awesome!! means it was built right , that means if you built it to last , and the rest of the car was built that same thought in mind, your ride should last.

Im with Scot W. after riding in you car, work with what you got, no electronics with the LS, no muss no fuss there. Maybe do a F.A.S.T EZ-EFI , for the mileage and tune for your driving habits..



Yes go with the 8.5 rear, & upgrade the rest.

I got aways to go with mine, to compete at you and Scot's level... but watch out!!

Again thanks for the ride along... felt good to feel what a G-body can be built to do.

So an 8.5 SS rear can hold up to the rigors of autoX? And Mr Reed I will need your help in the near future for my 455 regal swap!

Unless you include "Pro Solo", which has a for-real drag strip start against a car beside you running a mirror-image course to yours, autocrossing isn't all that tough on the rear, parts breakage-wise. What autocrossing is tough on is the clutches or cones (power-on, the clutches/cones want to lock, but the tight turns want to make them slip more than they have to in most street driving). The cones in an Auburn are perhaps a little more durable than clutches (and I think you can get a special racer-oriented version of one of the Auburns through Sam Strano).

FWIW, I ran several years of street driving plus three full seasons of autocrossing with 7.5"/7.625" Auburn and Richmond Gear stuff that I installed myself, with zero durability issues.

My rear is a stock 7.5 that came in the Monte from the factory...Precision 3.73 gears...stock axles...stock drum brakes...aluminum cover and an Auburn Super Brute diff. I use Redline or Amsoil gear oil with the ACDelco friction modifier. The rear has held up very well for what I have been doing to it the last two years!

I rebuilt the drum brakes last year when I installed the longer wheel studs and with the front Baer Track 4 set up...this thing really stops on a dime. It's weird...almost like I don't even need rear disc for what I am using the car for. You can see the brakes being rebuilt earlier on in this build thread.

The tires I had on the front before were 255/35/18....and these new ones are 275/35/18.






In my HHR and ready to go have them mounted!!!

[SicMonte]

So I took the two front tires to get mounted at my old work...Trick Trucks in Lanham MD. These guys specialize in rim/tire packages so I knew they would take care of my tires and wheels. They did a great job!!!!!










Proof that CCW's are true three piece wheels....the seam is covered in silicone to prevent air leaks.
