After checking out many options I bought the Canton Marine big block pan. This has 9 qts with the filter. There is no cross member on my SPF to interfere with the
oil pan. This ment I did not need the front sump pan which is designed for Mustangs etc to clear the front cross member. The marine pan is basically flat with a slight slope to the rear. It runs a custom bolt-on center pickup. The pickup is enclosed in 2 full width trap doors to keep the
oil in the center of the pan. The engine builder indexed the pickup to 3/8" from the bottom of the pan and then bollted it to on to one of the 4 bolt main caps. This pan has slightly less depth than the Road Race pan (3/4" I believe). The pan is also made of slightly thicker metal to resist rock hits. I did not go with an aluminum pan because of the potential breakage issue. I added the windage tray and the custom ARP studs on the mains on which to mount the tray. Cobrashoch is correct about the bellhousing being the lowest point. I used the Lakewood bellhousing and trimmed it off to give more ground clearance. The final parts for the oiling system included the Canton 215 degree
Oil Thermostat and the Canton 3 Qt Accusump. I have posted pictures of all the oiling parts and a shot of the actual ground clearance in my gallery.
