Melling has been the leading manufacturer of performance and racing oil pumps for over 65 years. This racing pump features an extended drive shaft to prevent deflection at higher RPMs. This is our race-prepared version of the small block racing pump - it's a standard-volume unit for less parasitic drag, and the body and internal parts are Cryo treated and Teflon coated, then hand-assembled with a high pressure spring. A heavy duty oil pump drive is necessary, and we have found the ARP oil pump drives are the very best.
