Has nothing to do with who built the engine and everything to do with the limitations of a wet sump pan built to fit a particular application, rulebook, etc, and the compromises that result. That and the fact that it takes a number of rotations to get the oil to all the parts under pressure after an engine has sat for awhile.

Maybe your guy has an exclusive pan design that no one else knows about that 100% keeps the pickup submerged. Or uses an oil additive that works as well as the BG MOA they use for that demonstration where they run a small block Chevy for 20 minutes with no oil pan. And it lives.

Point me to a prominent engine builder who has a good reason not to use one and I'll listen to what he has to say and weigh the options for myself.
