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.

Chevrolet Performance DOD/AFM delete kits are a cylinder deactivation delete kit for the Chevrolet Gen V 5.3L engine. Why delete the DOD/AFM systems you may ask? Some performance drivers and engine builders prefer to have all cylinders active at all times. Other reasons are older systems that wear out over time and can become unreliable, or that sound of the engine may become unpleasant when cylinders drop out. These DOD/AFM delete kits are designed to remove the Active Fuel Management (AFM) and Displacement On Demand (DOD) Systems from the Gen V 5.3. engine to provide a solution to all the above noted issues.

Something great just got better! Twisted Wedge 170 cylinder heads now feature updated A356-T61 machined castings previously reserved for Trick Flow's 11R series heads, including a .625" thick deck for more power-making strength. The castings' billet-like appearance seriously increases the cool factor too. Twisted Wedge 170 cylinder heads have Trick Flow's pioneering Twisted Wedge combustion chamber to reduce valve shrouding and enhance high-lift flow. The design features altered 15° intake/17° exhaust valve angles, which tightens the combustion chamber for increased compression and improved piston-to-valve clearance. That allows the use of higher lift cams with stock pistons—even with the 2.020" intake valves! CNC-profiled combustion chambers with relocated spark plugs optimize combustion efficiency, and a choice of 58cc or 61cc combustion chamber volumes allow builders to dial-in the perfect compression ratio. High-efficiency, Fast As Cast® runners and a competition level, multi-angle valve job deliver near-CNC-ported power and airflow at cast head prices. Assembled Twisted Wedge 170 cylinder heads come with top-quality stainless steel valves, bronze guides, PAC Racing valve springs, thread-in 3/8" or 7/16" rocker studs, and chromoly retainers to ensure great durability and longevity. Some Twisted Wedge 170 cylinder heads are emissions-legal under CARB E.O. #D-747-1 for 1996 and earlier Ford 289, 302, and 351W engines. Cylinder heads are available fully assembled or as bare castings. Sold individually.

It is for good reason that virtually every top professional engine builder relies on ARP Pro Series head studs for their all-out competition powerplants. Simply stated, there's not a better stud setup on the market today. ARP uses a premium-grade 8740 alloy that is rated far superior to "aircraft" quality. Then, each stud is placed vertically in special racks and precisely heat-treated to 200,000 psi. ARP studs are thread-rolled after heat-treat, which gives them about 1,000 percent (that's ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice).
