The "hemi" pan is a cost effective option... about one inch deeper than stock. In theory +2 quarts for 6 quarts in the pan but it works better with 5 in the pan. The Milodon circle track pan is an (expensive) option then there's a custom pan from Charlies with kickouts... kinda like the circle track pan.

With the Hemi pan in a very aggressive application, a pressurized oil reserve tank may be a good choice to make sure there's always oil.
