As I assembled it, I plastigaged all of my bearings. After micing the journals, same with rod bearings. I ended up putting STD bearings in(if I remember they were at .015). it has always turned with a little tight. As I added more(replaced original pistons with new rings, new lifters) its gotten a little tougher. I could still turn it with a breaker directly on the crank snout, but I'm afraid I'll break the balancer bolt if I put any more torque on it. I cringe at the thought of tearing it completely down and starting over.
