Holley's popular cast aluminum oil pans (P/N 302-3, 302-3BK, and 302-5) are designed to swap LS engines into trucks, muscle cars, and more, has just been brought to the next level. Vehicles that endure prolonged sessions of braking, turning, and accelerating need extra protection from oil starvation. That's where the 302-12 oil pan baffle comes in. This oil pan baffle kit is designed to maintain proper oil level at the oil pump pick-up during vehicle accelerations, both lateral and linear. The baffle maintains the oil at the oil pump pick-up preventing loss of engine oil pressure during maximum cornering in a high-performance touring or road-racing, as well as under hard acceleration in drag racing vehicles. The baffle is fabricated from sheet aluminum joined by TIG welded joints. Directionally positioned one-way trap doors allow oil flow towards the oil pump pick-up but not away. This baffle is designed to be used in the Holley P/N 302-3, 302-3BK, or 302-5 LS Swap oil pans with the standard pickup, and is a drop-in replacement for the standard tray baffle.
