Summit Racing ™ Pro SBF and 303+ Hydraulic Roller Cams

Are you looking for a great made-in-the-USA cam for your 5.0L H.O. engine? Pro SBF and 303+ cams start with American bearing steel billets, the cams are precision-machined on a modern Landis CNC grinder with CBN diamond wheels for unmatched quality. Still thinking in terms of LSA and duration splits? These cams are designed on a whole other level by tuning each of the four valve events separately. Having a cam with attitude doesn't mean it has to be a dog at low rpm. We've tuned each of the four valve events to maximize power and torque in the range you will be running in. You CAN have your cake and eat it too. Summit Racing's™ affordable E303 Plus, B303 Plus, and F303 Plus are designed to tune easily and have the idle you're looking for. We've applied the latest lobe technology, and the valve events have been tweaked for modern intake manifolds and cylinder heads. The Pro SBF lineup ranges from a 204-duration daily driver tow cam to a 252 duration 8k rpm barn-burner. They are ground in fine increments to match your specific engine's top-end, displacement and intended rpm range. The lobes are stable to high-rpm and easy on the valvetrain, but we've added lift to take advantage of the high-lift flow of the latest cylinder heads. They are more aggressive with more overlap than their 303+ brothers for more attitude.

COMP Cams Thumpr Hydraulic Flat Tappet Cam and Lifter Kits

COMP Cams is bringing the muscle car sound back, and it's nastier than ever! Let's face it--few things serve to grab our attention at a car show or cruise night more than a car with a thumping, high performance idle. In an ongoing quest to provide you with the performance and sound you demand, COMP Cams engineering team proudly introduces the Thumpr Series cam and lifter kits. The lobe profile and grind characteristics of these Thumpr camshafts use a combination of an early exhaust valve opening, a long exhaust duration, and a generous amount of intake and exhaust overlap to maximize the rough-idling characteristics of the cams. This gives you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in different grind profiles; each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range. Thumpr Series cam and lifter kits deliver a substantial power increase over an identical hydraulic flat tappet grind without sacrificing reliability or ease of maintenance.
