I am rebuilding the 5.0 in my 95 GT. I sent the block and the crankshaft to simply be cleaned by a machine shop as they had no problems before and still looked good after disassembly. My problem is I got them back and started installing main bearings and after installing only one cap the crank is so tight I can barely turn it with a ratchet. I did plastigage the crank and it was around .001 which I am aware is incredibly tight. So I assumed that my new bearings were the problem. I went to the auto store bought standard bearings again and still too tight. Just to try it I reinstalled the old bearings and it still wouldnt turn. Now I'm incredibly confused becuase no changes were made to the crank or the block and now the old bearings are too tight to turn the crank.
Please help because it seems like the crankshaft has grown and that is the reason it wont turn. Obviously impossible......
