Re: How tight should a rebuilt engine be?
I sense some mixed signal are being sent here. Is the engine tight from babbitt clearance -or piston-to-cylinder wall clearances?
Generally speaking, some builders set up the mains & rods very snug because they do not burnish the babbitt. Usually in this case, after the initial start up and running for a minute, if the engine is stopped and allowed to cool, the babbitt will have reformed around the journal pin and it should be fairly easy to hand crank. If the pistons are tight, THAT is a diferent issue and likely won't correct itself for a long time.
