• Trap door baffle assembly maintains consistent oil coverage at the pickup during acceleration and deceleration.
• Anti-slosh baffle prevents oil migration under hard cornering and braking.
• Designed to clear S10/Blazer chassis crossmember and steering geometry when using a SBC V8 swap.

Product Description

The Moroso 20177 is a 9.5-inch deep steel oil pan purpose-built for Small Block Chevy V8 engine swaps into the Chevrolet S10/Blazer and GMC S15/Jimmy chassis. It is engineered specifically for 1986-and-newer SBC engine blocks featuring a one-piece rear main seal and passenger-side dipstick, making it the direct counterpart to the Moroso 20176 (which serves pre-1985 driver-side dipstick blocks). The deep 9.5-inch sump holds 6.5 quarts and positions oil well away from the rotating assembly, while the trap door and anti-slosh baffles ensure consistent oil supply to the pickup under acceleration, deceleration, and cornering.

Built from thick, laser-cut steel with a black powder coat finish, the 20177 provides a durable and leak-free installation. The pan is dimensioned to accommodate the tight clearance conditions common to S10/S15 chassis SBC swaps, where crossmember and steering geometry can limit oil pan options. Builders should verify ground clearance and crossmember fitment for their specific vehicle configuration before installation. Use Moroso oil pump pickup No. 24170 or No. 24350 with the appropriate SBC oil pump, and pair with Moroso gasket No. 93151 for a correct one-piece rear main seal block installation.
