::I am in first gear and just stomping it, the tires are 215/60/14 road tires (nothen special) rear gears is 3.00 and i was told it was a posi 9" rearend, but looks like a normal 8" rearend to me, i am guessing its limited slip "open" as it will spin the passenger tire 75% of the time and the drivers 25% of the time and both in gravel or rain covered roads. I mean heck, i didn't add anything that would give me more power - just added universal traction bars and wham it spins its tires hard, not like a 350hp muscle car would, but enough to get alil sideways on a turn or enought to get some smoke going from the light. Weird...... I did look at the rubber stoppers and they are contacting the leaf springs and compressing as the rubber has dirt from the springs on it. I haven't wound the engine up and launched as of yet - I am trying to take it easy with the car till i get the suspention rebuilt and the tranny rebuilt, so i am not sure if it will hook, but from a rolling 10mph start in first gear - it has some nice get up and go with some squeel. It didn't do that before hand...

::Dave, There is no limited slip open rear as you call it. You need to see what you have by doing the following. Block the front wheels and one rear wheel so the car won't roll. With the emergency brake off and car on level ground, jack one side of rear end off the ground a few inches. With the trans in neutral see if the wheel will turn by hand. If it does you have an open rear. If not it would be a limited slip. Even with a limited slip, if the right side spins much more than the left then the clutch discs in the limited slip unit are wore out.
:..Seems you have a good engine in your car. If the trans has a lower ratio first gear than most, that may be why it performs as it does. Determine what you really have then go from there. I still think better can be done with a different setup for traction bars. I have the same bars and there laying under the bench.
