5.9L, Melling HV pump, stock pan, dual remote oil filters
Hmm, I got a stock style Mildon oil pan and it has a baffle welded by the rear of the sump. I run the HV oil pump too and spin my 340 to 6,300. Once I went flat out in top gear for a good bit, I have no problems with it.

I do run 5 full quarts and top off when a half quart low, run the KN 2004 oil filter--the short filter
