This Competition wet sump is for '86 and newer Small Block Chevys with a one piece seal. The oil pan is designed to be replacement/upgrade for the GM performance circle track crate engine "late model" pan. The deep "T" sump gives increased oil capacity in a shallow sump design. It has a 7" deep, 12" long, 14" wide sump and a 8 quart system capacity. Requires one of our pickups.
