This BBC stock depth wide sump oil pan is for Mark IV big block Chevys. It is designed with a shallow front with angled corners to clear the large cross members in early Camaros and Nova's and '68-'72 Chevelle. It has an 8" Deep, 12" Wide, 9-1/2" Long sump with a 7 quart system capacity. Due to the extra shallow front section of this pan designed for large cross member clearance our main cap mounted wind age trays will not clear this pan. This pan requires our 20-170 pickup.
