Willie: Check to see if your 41-42 221 doesn't have a full set of
heavy wall cast iron repair sleeves (FMC remanufactured ?) rather than
Ford's .040" thin wall steel sleeves. Bore size? Rods & mains sizes?
See if there are rebuilder's size stamps on outer edge of 1st crankshaft counterweight.
81 (39-42) cranks had 2" rod journals. Rod cap Cast "s should be 91
or 21.
Hey.. good picture showing concave rather than flat block (41-42)
sidewall; also no casting core hole bumps above pan surface.
My opin--try to clean up bore & use with minimal change; want bigger, start with 239 engine.
Have fun with them!
