An older member of the COMP Cams grind family, the Magnum series of camshafts offers excellent performance gains over stock without the added wear and tear associated with more aggressive camshafts.

“Edelbrock Rollin’ Thunder Camshaft No: 2281 is designed for 351W Ford V8 engines and produce optimum torque from the low-end to the mid-range. Rollin’ Thunder camshafts match with Performer manifolds for vehicles operating from off-idle to 5500 rpm. They are smooth idling cams for daily drivers, trucks, vans, RVs and 4x4s. You can expect a major improvement in throttle response and torque. In the manifold section you’ll find torque graphs showing the power gains from Performer manifolds and Performer-Plus cams. All camshafts include flat tappet lifters (except for cams designed for use with stock roller lifters), assembly lube and instructions. This cam produced 449HP and 413 Ft Lbs of Torque when paired with RPM Air-Gap Dual Quad intake manifold No: 75354 and Performer RPM cylinder heads No: 60255. Must use a high stall torque converter. Will not work with stock valve springs. Camshaft specifications: – Intake duration: 235 Degrees – Exhaust duration: 238 Degrees – Intake lift: .573″” – Exhaust lift: .582″” – Lobe separation: 112 Degree – Intake Center Line: 107 – Vacuum: 10″””

Designed to deliver an aggressive, hard-hitting exhaust note at idle, the Thumpr camshaft series from COMP Cams also delivers excellent horsepower gains and a broad torque curve. A perfect choice for muscle cars and street rods.

Featuring a quicker valve opening, the Xtreme Energy camshaft profile provides increased responsiveness and more area under the lift curve than older, slower grinds. Designed to increase performance without sacrificing driveability and creature comforts,

Made In USA. 4 oz. Melling engine assembly lube, MELL-LUBE, is formulated to be an initial lubricant on camshaft metal surfaces as well as related valve train parts. The added zinc material (1400 ppm) provides MELL-LUBE with added protection to prevent scoring and galling during initial engine start-up for both newly rebuilt and / or remanufactured engines. In addition, MELL-LUBE contains corrosion inhibitors to prevent rust and pitting of components. MELL-LUBE mixes with any engine oil and will not clog filters. Melling recommends MELL-LUBE be a part of every camshaft install.

An older member of the COMP Cams grind family, the Magnum series of camshafts offers excellent performance gains over stock without the added wear and tear associated with more aggressive camshafts.

Ideal for use with mainly stock components like rocker arms, intake manifolds, cylinder heads, compression ratio, torque converters and rear gear ratios, the High Energy camshaft grind family is a great choice for street performance applications.
