Default th350 binding after swap? need help!!!

So I picked up a nice built th350 from my buddy who had it gone through just before he sold it to me. Anyway I did the swap from a t56 and now I've got a strange problem. When the car is up on jack stands it engages all gears and the rear tires move. As soon as I put it on the ground and try engaging the gears its like the ebrake is on. The trans engages and the car torques up like it wants to move but doesn't.

The fluid is full. The only thing I can think of is the driveshaft. I have a long tailshaft th350 and reused my driveshaft except the yoke. I put one on about 1 inch longer because mine seemed to be a little short.

If you have the 9" tailshaft the stock ds will work. It looks short, but its not, It works. Sounds like that might be your prob.

Maybe it is. I will check the driveshaft at ride height. Other than that I've got no idea. Maybe pinion angle.
