ok, we just got my brothers motor all put together, and it is hard as hell to turn over. I mean hard, we even broke a ratchet. When we installed the crank, it spun freely. Once the rod bearings and rods were installed it started doing this. We didnt know if it was just cause everything is tight or if they sent us the wrong rod bearings.
standard bore new pistons and rings new rod, main bearings the crank spun freely with just the mains on so Im pretty sure its the rod bearing size but just wanted to see what you guys think or if this has happened to anyone else. -------------------- "One of the most Crazy and Undecisive Members in central Illinois"

I would say look at cap orientation (Mitsu77 said) and torque specs on those.... a thin coat of assembly lube never hurt and now that you have had problems, once you figure out what was up, pull all of your rod bearings out and make sure that you haven't flat spotted them or caused excess wear on them from things binding up... bearings are made of very soft babit type material very easy to damage
