I like replacing the 402 pan with the 1970/71 Street Hemi 440 6 pak 6 quart oil pan and pick up. I use the stock 3/8 pick up on my 518 C.I. pump gas stroker in my Duster, I shift it at 7000 + RPM on every run, car runs low tens at 132+ MPH, no oiling problems so far, going on five years with that set up on several other motors also
