MOROSO, ENHANCED, 4-VANE, VACUUM PUMP-MOR22642

The included mounting bracket is designed to fit small and big block Chevy engines or motor plates. Please see the 'Required Parts' tab for brackets for other applications.Built for racers and engine builders who craved the performance, Moroso racing vacuum pumps are manufactured from billet aluminum and feature a precision-machined shaft, rotor, and bearings that will withstand the rigors of racing. They work by producing high crankcase vacuum, which increases power by improving ring seal, preventing blowby, and detonation. Allowing the use of lower-tension piston rings for less friction. These positive pumps are much more consistent and effective than header-mounted evacuation systems.
