I think the only thing you can do besides a high pressure pump, is go to a dry system. This would be a good thing if the truck is going to be spending long amounts of time parked between tows, because it gives you the option of turning on the oil pump before you start the engine, making sure that oil is in all the places it should be before the engine needs it to be there.
Many performance parts manufacturers make parts and complete systems. It is a somewhat costly endever though.
Here's how it works: http://www.moroso.com/articles/articledisplay3.asp?article=AboutDrySumpSystems.html
if isn't something that you want to do, you could go for a large capacity oil pan. Summit sells a Moroso street/strip pan for 4x4 460 trucks for $209.88 Part # MOR-20612
Any way you go, let us know how it works! :lo1l:
