I am restoring a 61 K10. Got it from CA off of eBay. It had a 350 engine which was blown and a TH350 xmission installed by someone in the past. I was trying to see if they had done anything to the Drivetrain. I jacked both back wheels up and spun one side. Only one side turned. It has really big tires so it might be possible that all that tire weight was enough resistance to keep the other tire from spinning or it could be an open rear end. What seemed really odd was that the drive shaft turned about 1.9 times per turn of the tire. Does not mater if one tire is on the ground or both in the air. I moved to the front, locked the hubs and I get less that 2 there. I was told by the guy I purchased it from that the guy that switched out the engine and trannie pulled sleds with it. With that info, I was thinking a 4 plus rear end might be in it. Figured I must messed up in the way I was trying to check it. What am I doing wrong?
