This Big Block Chevy 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 Novas 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 main cap mounted windage trays will not clear this pan.
