Ever since its introduction, GM’s Gen III (LS1,-2,-6) engine has quickly become the “preferred choice” among many engine builders and performance enthusiasts. Right from the factory, the GM Gen III engine boasts a surprisingly efficient induction design, reduced weight and impressive power output. As the leading developer of high performance Gen III valve train technology, COMP Cams® has engineered a full line of products proven to release the incredible horsepower and torque hidden inside while never sacrificing ever-critical reliability. Regardless of the application, COMP Cams® has the GM Gen III engine products that deliver the performance you demand. In their never-ending quest to raise the bar of street-able performance, the design engineers at COMP Cams® have added three brand-new solid roller profiles to their already impressive lineup of Gen III-specific cams. Engineered specifically to take advantage of the phenomenal efficiency of the FAST™ LSX™ Intake Manifold, the newest members of the XFI™ line of Gen III camshafts deliver some of the most aggressive lobe profiles that have ever been designed for street driven Gen III-powered vehicles – resulting in massive increases in horsepower output, throttle response and upper rpm capability over the factory hydraulic roller patterns.

When you think about the car of your dreams most likely a “thumping” high performance sound is one of the first things that comes to mind. Now anyone with a Ford Windsor 221-351w engine built between 1969 and 1995 and originally equipped with a flat tappet valve train can make those dreams a reality. While these camshafts were designed for the late 5.0/351W firing order:1-3-7-2-6-5-4-8, they are compatible with all 1963-1995 Small Block Ford engines, with a simple firing order change required for early motors.

The new Thumpr® series of camshafts generate not only excellent power and torque figures, but a serious high performance camshaft sound. Available in three different levels, termed Thumpr™, Mutha’ Thumpr™ and Big Mutha’ Thumpr™, these are the perfect camshafts for street rods, musclecars and hot rod trucks.

COMP Cams® Aluminum Shaft Rocker Arm Systems are a popular choice for professional engine builders who desire increased valve train and cylinder head stability for improved performance and overall durability in all-out race engine applications. COMP Cams® announces the expansion of their shaft rocker arm system line to include nine new applications, including GM, Ford and Chrysler engines. Constructed from 2024 aluminum, these high-tech rockers ride on an 8620 hardened steel shaft and feature an efficiently designed oiling system that ensures consistent flow. Rocker arm ratios for these assemblies range from 1.5 through 1.7:1, depending on cylinder head application.

COMP Cams® announces the release of 11 new intake and exhaust valves in a variety of diameters and stem lengths for competition-minded Small and Big Block Chevrolet engine builders. Made from 21-4N forged high-strength steel alloy with 50 HRc minimum hard tips (which eliminates the need for a lash cap), these valves are state-of-the-art, delivering tremendous performance and durability. Recommended for all hydraulic, mechanical and roller lifter applications, these valves feature hard chrome-plated 11/32-inch stems with proprietary oil retention surfacing, not thin flash plating.

For performance enthusiasts looking for improved power, COMP Cams® new Sportsman Valves are just the ticket. To increase flow without increasing the valve diameter, high flow underhead fillet relief was designed in. In addition, the spiral-polished fillets generate a higher flow rate with reduced radial crack propagation, increasing their resistance to failure. COMP Cams® Sportsman Valves include all of these high-tech advancements, yet are affordable for any budget-minded engine builder.

Innovative new lifter design yields weight savings and maximum reliability for solid roller equipped Gen III engines

In their never-ending quest to provide the most advanced valve train products in the world, the COMP Cams® engineering team has recently introduced a new, improved solid roller tappet to the Endure-X™ line. A weight savings of 14 grams per tappet over the earlier #8950 Gen III

solid roller tappets means that these ultra-precision quality lifters will allow your Gen III engine to rev even higher – thanks to significantly reduced valve train weight. An enhanced, pressure fed oiling design, including EDM Oil Injection™ to the roller axle and bearing, ensures long life,

New BBC retro-fit hydraulic roller cams provide unmatched musclecar sound & power. When the Big Block Chevrolet engine debuted in 1965, it revolutionized the high performance world. The new COMP Cams® Thumpr™ Camshafts take the original Mark IV engine one step further with a line of three retro-fit hydraulic roller camshafts that not only delivers excellent power and torque gains, but includes another important feature – true high performance camshaft sound. For those folks who desire not only the performance but the sound of power, COMP Cams® Thumpr™ Camshafts are the perfect component for the job.
