The pan you have looks like the 1966 to 1969 Hemi pan based on how it hangs down below the K member, the Hemi cars and some of the 440 cars had a skid plate welded on them to help prevent those oil pans from dragging and hitting over speed bumps when going fast
Look at Summit for their 1970/1971 hemi and six Pack 6-quart oil pans and the stock 3/8-inch RB oil pick up The sump is longer and shallower so no need for the skid plate and works really well on street cars, I use them all the time now for any 1966 to 1971 B and E body B, RB or 426 Street Hemi motors I build
I had one on my old pump gas Duster stoker motor, it ran as fast as 134.+ MPH at 9.993 ET in the 1/4 mile with no oiling issues as long as it had the oil level above the add mark before making a run, if I ran it at one quart low it would start to loose oil pressure about 200 ft after the finish line letting after letting off
Summit oil pan part # G3511, Melling pick up part # 63-S4
