The Moroso Dry Sump oil pump is one of the top choices made by professional drag racers today. The pressure section feeds oil to the block, while the scavenge sections pull oil from special pickups in the dry sump oil pan and can be routed to pull excess oil from the lifter valley. This keeps oil from sloshing around in the top of the engine and running down onto the rotating assembly, reducing windage and increasing horsepower.
