Written by Moore Good Ink 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. For further information contact: Jon Kaase Racing Engines, Inc. 735 West Winder Ind.

Written by Moore Good Ink Excellent recovery and creep-free characteristics, unsurpassed flow, tool-free adjustment, boost-reference port included as standard fitment, lightweight, and shaped as a direct bolt-on replacement. During 1942 Weldon began producing pumps for the US Department of Defense. By the late seventies, fast boat owners requiring rugged, dependable pumps to supply fuel to multiple engines had acquired Weldon’s services. In the mid-eighties, GM’s NHRA Pro Stock program needed a more robust fuel pump and they called on Weldon. The early nineties brought about an increased demand for high pressure pumps and bypassing regulators for fuel injected race cars and street driven vehicles. Though Weldon Racing Pumps is a separate entity from their aircraft/aerospace division, the stringent disciplines of aircraft quality assurance were applied to the design and manufacture of the A2046. In a “pressure creep” test using 4 ports (see attachment) minimal pressure creep can be observed. When measured in one-second increments over a 15-second interval, the new Weldon regulator gains approximately 1.5 lb compared with a leading rival, which gains approximately 4 lb. The A2046 will deliver similar pressure-creep gains when using only one or two ports. Body & valve assembly: CNC-machined from 6061 aluminum, the lower and upper chambers of the regulator body are separated by the fast-acting valve assembly. The body of the valve assembly, which contains an intricately machined stainless steel poppet valve, is produced from white Delrin® and is precision-drilled to provide fuel evenly to one, two, or all four ports without affecting flow rate. Functioning on pressure differences between the fuel pump and the needle-and-seat valves in the carburetor...
