Getting block prepped for the hot tank

Add all this up and you have a winner . I would also add , 1/8" drill between the lifter pedestals to aid oil return, 3/16"long drill from main bearing journal to lifter galley for more oil volume to the mains (it is step drilled from factory) and debur the casting flash. I would thread chase the bolt holes before and after cleaning just to make sure . You'd be surprised at how much junk can be in there . Costs little , rewards are big . CHECK EVERYTHING !!!
