Chev SB & BB V8 4 Stage Dry Sump Oil Pump
Product Information
Moroso dry sump oiling systems are the safest, most dependable oiling systems available. They're popular in all forms of racing, especially where low chassis height is important for good handling. Horsepower gain is maximized because there is virtually no oil in the pan and no internal pump, allowing the windage tray or screen to run the full length of the pan. Other advantages of a dry sump system include a remotely mounted oil tank for increased capacity, the ability to easily add remote oil coolers, more consistent oil pressure, adjustable oil pressure, improved scavenging, and increased ring seal due to greater pan vacuum. Brackets are included.
- Steady oil pressure throughout RPM range
- Consistent oil pressure at high heat levels
- Increased vacuum
- Consistent oil pressure at high vacuum levels
- Oil pressure adjustability, allows for finer tuning of pressure levels
- Internal manifold with -16AN return, no need for separate manifold
- Built-in mounting bracket designed for engine compartment constraints
- Two pressure outlet locations for easier plumbing
- Includes all necessary fittings
- Vertical oil pressure adjuster makes it easier to change oil pressure settings
Application: Chevy Small Block Gen 1 283-400 C.I.D., Chevy Big Block Mark IV 396-454 C.I.D. & Gen V/VI 454 C.I.D.
Oil Pump Style: Dry sump
