Holley aluminum LS valve covers will give your Chevrolet LS Series engines a totally new look. Manufactured from cast aluminum, they come in four different finishes, and feature a billet aluminum oil fill cap. Some valve covers in this series eliminate the need for the factory ignition coil bracket. Instead, the coils bolt directly to the valve covers for a nice angled look! Holley aluminum LS valve covers reuse the factory gaskets and bolts, will work with .750 in. lift camshafts using stock-style rocker arms, and fit all ignition coils with 72mm spacing.

COMP Cams is bringing the musclecar sound back, and it's nastier than ever! Few things grab our attention at a car show or cruise-in like a thumping, high performance idle. In fact, one of the most frequent questions from customers is, "What camshaft will give my car that mean-sounding idle?" For the performance and sound you demand, COMP Cams engineers introduce the Thumpr camshafts—a new series of hydraulic flat tappet cams. The lobe profile and grind characteristics of Thumprs use a combination of early exhaust valve opening, long exhaust duration, and a generous amount of intake and exhaust overlap—to maximize the rough-idling characteristics of the cams. They give you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in several grind profiles; each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range.
