a friend of mine is rebuilding a 305 chevy i have out of a 1983 pontiac trans am. it spun a rod bearing but i had the rod cleaned up and we had the block looked at and it looked ok. put in all new rod bearings, new rings, etc. and everything was ok until he put in that #8 piston. for some reason now he can't manually turn the rotating assembly. any idea what would cause this?
