King XP-Series rod bearings feature advanced metallurgical and geometric technologies that meet extreme performance loads. They were developed for all performance applications that use forged steel aftermarket crankshafts and produce high loads for extended periods. King focuses on one product—bearings—and nothing else. Their innovative race-only Xtreme Performance Max Black Tri-Metal rod bearings have a 24 percent stronger overlay and 17 percent more fatigue strength by using a micro process called SecureBond. Built with enhanced tri-metal, King XP-Series rod bearings layer copper-lead construction with a nickel plate barrier and a lead/tin/copper Babbitt overlay over a steel backing in an adhesion process that provides superior stability and durability. King's advanced control measures hit a bull's-eye, maintaining wall thickness tolerances far tighter than their competitors—at an amazing +/- .0001 in.! XP-Series rod bearings are narrowed on the crank cheek side with increased crush height for improved bearing-to-bore contact, heat transfer, and reduced spin potential in high-rpm applications.

ACL Performance offers Race Series rod bearing sets for a wide range of vehicles. These high performance tri-metal engine bearings are designed to withstand higher RPM conditions. They feature a high-strength overlay plate with reduced thickness for improved fatigue properties. Select the crankshaft undersize and quantity recommended for your year/make and engine application. Additional details: * Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing. * Increased crush for improved bearing retention * Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing * Increased eccentricity to compensate for bore distortion at high RPM and to assist in the formation of hydrodynamic oil films * 3/4 in. grooved main bearings to optimize bearing load carrying surface area and oil flow to the conrod bearings * Tight consistent wall tolerances to help you maintain consistent clearances * Enlarged ID chamfers on bearing edges (where required) to accommodate large fillet radius on performance crankshafts

Proform stamped steel valve covers are 20 percent thicker than typical aftermarket valve covers. This greatly reduces the likelihood of leakage around the valve cover flange area caused by fasteners being over-torqued. These heavy-gauge steel covers are officially licensed GM products and bear the Chevrolet logo and Bowtie Emblem, unless otherwise specified. They're available in both tall and short heights, with either a chrome or black crinkle finish. Oil-restricting baffles are offered in many valve covers, for those who want to maintain the PCV hookup; and all covers are supplied with grommets for use with an air breather and PCV valve.

King HP-Series cam bearings are precision-machined to tight tolerances to control installed oil clearances, reducing operating bearing pressure. These cam bearings are constructed from seamless steel tubing with a thin layer of lead based babbit material to reduce microscopic deflections. The babbit is quickly cooled in the casting process to achieve a very fine grain structure, doubling tensile strength, therefore, the HP-Series offers much more fatigue strength than conventional bearings, and can withstand racing spring loads, while maintaining the excellent surface characteristics of babbit. King also offers HP-Series bearings with a fluoropolymer coating. Bearings with this coating retain engine oil on the surface, even under extreme heat and pressure—a great advantage! Plus, being a lubricant, it provides backup during start-up and in the event of momentary oil starvation. Use track-tough King HP-Series cam bearings in your engine—and experience the difference.

ACL Performance Race Series main bearing sets deliver everything performance bearings should be by utilizing design, metallurgy, engineering, precision quality control, and of course, years of knowledge and experience. Main bearings feature multi-layered tri-metal copper alloy construction that blends characteristics to provide high strength and excellent seizure resistance. They are manufactured to exact tolerances ensuring a reliable fit and helping to maintain consistent clearances. Main bearings are augmented with extended grooves, as well as other bearing enhancements, like increased crush, bearing eccentricity, and enlarged I.D. chamfers. ACL Performance Race Series main bearing sets are produced in standard and extra clearance versions, with or without friction reducer coating, and with modifications to meet specific build requirements, such as narrowed bearings that permit additional edge clearance when running crankshafts with exceptionally large fillet radii. In the heat of competition proven technology always comes through. The choice for your build should always be ACL Performance Race Series engine bearings. Choose the main bearing set designed for your vehicle.

Oil volume is nothing to take lightly, so why reuse an old oil pump or settle for something less than great, when you can have a Sealed Power pump? They've been making quality, reliable performance pumps for decades. These high-volume oil pumps have increased rotor or gear section lengths for increased oil delivery to critical areas under extreme conditions. Their sturdy cast-iron pump body handles the stress associated with high rpm and added oil volume. The extra volume is helpful in maintaining oil pressure in rebuilds.

If you're building a serious performance engine, then you'll want to consider Speed-Pro Competition Series main bearings. They were developed in NASCAR and Pro Stock competition, so you know they're tough. The bearings are built on premium 1020AK steel backings and overlaid with Speed-Pro's super-duty H-14 alloy. That layer is then covered with a nickel barrier, followed by a thin lead-tin-copper overplate. However, unlike other performance bearings, there is no flash tin layer on top of that. Speed-Pro's engineers have determined that such a layer can actually move around under high loads—sometimes with undesirable consequences. Depending on the application, these main bearings have oil grooves for enhanced lubrication, while maintaining a maximum bearing surface area. They also feature Speed-Pro's exclusive contoured-flange thrust bearing technology for higher thrust-loading capacity. Competition Series main bearings are available in nearly a hundred configurations for countless vehicle and engine applications.

Sealed Power high-pressure oil pumps solve your oiling woes in your high performance engine. The higher oil pressure aids in maintaining the oil film thickness in many areas subject to extreme loads. Engines that operate under heavy loads but still use stock bearing clearances will benefit from a high pressure pump. Supercharged or nitrous applications can also benefit from performance of a high pressure oil pump.

These High Energy hydraulic lifters from COMP Cams feature a patented, constant orifice-metering valve that precisely meters oil to the rocker arms. Continuous contact between the metering valve and the precisely coined bottom surface of the pushrod seat is maintained throughout the engine's rpm range, eliminating excessive oiling at high speeds. The pushrod seat is made of a special powdered metal iron alloy, heat-treated for strength and wear resistance. The longer piston is produced with through-hardened steel that provides more bearing surface and increased lifter longevity. These lifters have a lightweight check valve disk that allows for quicker response, resulting in increased engine speed before valve float.
