Dave - If it's a simple
Oil pan clearance problem your facing, a custom low sump pan can be made by Armondo, Stefs, Avalon or others. The low point on my cars underside is the trannys bellhousing using a custom Stefs pan. A acusump type
oil recovery system is very recomended going this way.
If it's horspower gains your looking for, a topside engine vacuum system will get you to dry sump territory net power gains, with the fore mentioned pans.
If you are going to toss your car around really really hard, there is no substutute for a dry sump,,,,,,,,, PERIOD! They are a bit expensive though. Be forwarned there is different types of dry sump systems out there. Some better than others and some for specialized apps. like in boats and for tractor pullers.
Good luck!
