Another needed item is center/mid sump oil pan. There are 4 choices from what I have seen.
-Weldtech makes a custom aluminum pan with modified pick-up tube.
-Charlie’s makes the same custome pan and pick-up tube.
-Milodon makes one you can purchase through Direct Connection.
-Modify an original 3G Hemi pan (very difficult from what I understand)

A couple of items to be aware about on the pan swap.
-The windage tray is the actual pan gasket.
-5.7 oil pan gasket has different drainback holes than the 6.1L hemi.
-Two (2) additional holes need to be drilled at the rear of the oil pan gasket when using a Weldtech or Charlie’s pan. They are using two not used existing drilled/tapped mounting holes.
-Apply a very good black RTV to both sides of the oil pan gasket.
-When swapping pick-up tubes, the #1 main cap stud needs to be swapped with the #3 main cap bolt to properly secure the pick-up tube.
-If you car is a driver like mine, I polished my Weldtech pan by hand with Mother’s Mag wheel polish, washed it then clear coated it with High Temp Engine Clear paint.
-Always a good idea to have on hand a NEW o-ring seal fro the pick-up tube. A cut o-ring seal will aerate your oil and give you much grief, just ask some Chevy LS1 owners.
