318 crankshaft specs

also, I have seen engines used with pre balanced cranks and the piston balancing was done by shaving metal off of the ends of the rod caps.

If this was the case with his engines balancing that was done when whoever did the machine work and installed .060 pistons and in the event he had to get another crank....As long as he reinstalls a pre balanced crank ....his assembly would be no different than it was before and should not require balancing.

just my .02
