Winder, GA, April 2009: For the thirty years that the 385 series big-block Fords were in production, it was not unusual for their oil pumps to fracture and to break off without warning.
If the engines were treated with much gentility, they might have survived without drama. However, for those engines that were expected to perform with some enthusiasm, especially those that were modified and tuned, oil pump failure was almost inevitable.
Recently big-block Ford devotee Jon Kaase addressed the predicament. He altered the structure of the pump, provided it with sturdier mountings, and eradicated the likelihood of further failures. Moreover, he fits the new pump with the same impeller he employs on his championship-winning Kaase 820 CID Pro Stock engines, equips it with dual oil feeds to the rotor to improve idle and high-rpm oil pressure, and supplies it with superior ARP mounting studs and 12-point nuts.
Two versions of the pump are available: one for a front sump layout; the other for the more common rear sump arrangement. Sharing the same main body, the front sump pump suits earlier muscle cars and can be recognized by the angled flange at its inlet port. The rear sump pump accepts the long pick-up tube that takes its oil feed from the back of the engine.
These new pumps accommodate stock and aftermarket oil pickup assemblies and are bench-tested before shipping.
