If lowering it is going to create clearance issues with the
oil pan you can always go to an Aviad or Armando's Racing (
Road race oil pan) pan (#406 pan, Ford 289, 302, Cobra Replica: front sump 15" L x 7.5" D x 11.5" W) with kick-outs.
I had Armando Rodriguez build a custom pan to accommodate the angle the BBF is mounted at. It has a 3/4 length sump and the bottom of the pan sits 1/4" above and parallel to the bottom of the frame rails. It also has drain plugs front right and left rear, a bung for an
oil temperature gauge, and double the
oil capacity of the old pan.
Extra oil capacity would be a good thing if you're planning on running a supercharger, and an oil temperature gauge to monitor things is a good idea too (if you don't already have one).
