Are you wanting to keep all the original major parts in this motor? If so have it magnaflux inspected for cracks, everywhere If it mags good and measures good, within .0005 of the minimum and maximum factory specs. run it If you want to step the performance up some think about having that crankshaft offset ground from the factory 2.375 rod jourbnal size with 3.75 stroke size down to BB Chevy rod size and offset ground to 3.900 or 3.910 stroke, whichever the crank grinder can get out of it and buy a new set of forge H beam rods 6.800 or 7.100 long center to center and a matching set of forge pistons and enjoy the new found HP and torque of the longer stroke I have one of those motors(3.910 offset stroke 440 crank ) sitting in my shop right now waiting for the 1966 Dodge Coronet Deluxe to come back from the paint shop. I hate waiting on paint and body shops that promise two months and take six months
