New D/PS Firebird

Wow did not want to hear that. I rebuilt my rear end with aftermarket axles, 4.56 gear, solid pinion spacer,( which I hope makes a huge difference) new bearings, bars to support front of pinion to axle tubes, rear cap girdle cover, tig welded axle tubes, and 85w140 gear oil to hopefully take some of the shock . I then cut the housing ends off and straightened the housing . I put 8.5 x 26 m&t on the back. But I am going to leave 15 or so psi in them. That is an awesome new best time. I hope I can get my car to et that low. I think the tracks will start to open next week so I will let you know how it goes.
