I've ran high volume, high pressure oil pumps in all my BB engine builds since the early 1970 with 5 and 6 quart oil pans with no issues running them dry on the street or at the 1/4 mile tracks ever as long as the pan is full when sitting cold
My last pump gas car, 1971 duster with a 517 C.I. 400 block ran 10.30 at 127 MPH in the 1/4 mile with Eddy RPM heads, I moved that motor back right at 1.0 inches to the rear so the stock 1970/71 hemi 440 six pack 6 quart would fit in that car, I let it get down to the add mark before one race at Woodburn, OR 1/4 mile race track, it would start to drop oil pressure a little after I let off past the finish line adding the quart of oil fixed that
