M72HV bottom plate

My opinion here is the same as in your other thread. The mods you’re asking about are beyond the scope of the build you’re doing. A stock magnum with proper rod/mains clearance, tight lifter bores, and an HV pump (I add the high pressure spring also) will be more than you’ll likely ever need. I also baffle the stock pan to keep the pickup covered. If you’re road racing there is some modifications to do to the sides of the pan to help oil control but you said this is a driver. Why don’t you share the “future upgrades” so we can better guide you.
