572 oil system with A body Hemi K frame & mounts

sending it to my cam grinders crank guy . he's going to check it and fix any issues and add a hub reg for the flywheel and or torque converter . and i'm looking at all these brands now , ross didn't show any less then 4.5 bore . but again this block still needs a clean up bore . then i'll be real on what size bore it can be .
