Here's what I've run on my hemi for many years w/ no issues at all. Milodon pump w/ a stock cast iron pump cover. 7200+ rpm. Who popped a wheelie and bashed his oil pan on the return to earth  I'm glad it didn't tear it open   Yep, I've done in it a few times now. The last time it did tear the pan open. Put a nice Charlie's pan on it now, but the car may be retired for a while.
