A little more background. This is a 54 vette which does havea high pressure oiling system. Brand new oil pump with good pressure using a drill. Good flow out of all rockers. I pulled the rocker assembly off of the head to check all the hydraulic lifters Which are well oiled and move smoothly. Rods are all fine. I did put some Marvel Mystery oil in the cylinders about 3 months ago. Thinking its possible that oil has dissipated and it now needs more so I just added some ATF. No spark plugs are in and all of the valves seem fine with none of them sticking. I am assuming this has to be a lack of oil situation so possibly the cylinder walls are dry after several months. Very confusing since it turned so freely just a few days ago. Seems like it was fine and the quickly bound up. Also, So far I've only turned the engine a one revolution at a time while spinning the oil pump with a drill to check the rocker oiling. I won't be ready to start the engine for a couple more months. If oiling the cylinders again doesn't do it I'll move to loosening the connecting rods. I truly appreciate your comments.
