Hi, I have a 1973 Camaro, 350 bored .30 over, mild performance build. TH-350 tranny out to 2.73open gears. (my rear tire diameter is 26.1 inch 235/60r/15) Which doesnt hook up as strong as I'd like.

I want to drive this car on the street, it wont be used for anything but street and a little street racing. I probably wont go over 80 in it normally, maybe occasionally. I have found a trans am axle at the salvage yard, it seems to be a posi. Unknown gear ratio, but I assume its something like 3.3-3.42. The price is $175, i might get it for $150.

Any suggestions? would this axle significantly improve car's street performance for the cost? What should I look for in the axle to be sure it is decent without pulling the cover?

Also, any suggestions on what stall I should run on my torque converter?

Thanks very much

Pull the cover and count the teeth.
I had a 77 Trans Am. Yes it was a posi, but it was a 2.41 rear.
This will help you go backward, plus cost $.

The Trans Ams (late 70's at least) had 400 engines in them, with a fair amount of torque and could live with the 2.41, plus it helped conserve gas.

I was going to post a picture of the 8.5 posi so you would know what it looks like, but it wouldn't work. Then I noticed that there is a message that says "[img] UBB Code Not Allowed!" So I posted the picture in the engine and drivetrain forum. It has your name on it.
