COMP Cams Thumpr Hydraulic Flat Tappet Camshafts
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 camshaftsa 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 overlapto 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.

Great price. Great fit. Would buy again.
Fit well enough, needed to sand a little for a better fitment. Was not difficult in any way.

Lightweight but so is the original
When the package arrived it was in a very thin lightweight box that was crushed on one side. I thought for sure it was trashed. By chance…all was good. The lights are thin plastic but made very close to the original standard. They fit well on the car but the gasket needs to be tucked in around the edges. That material seems thin. The end result is actually a nice looking inexpensive light. Overall I am happy.
