COMP Cams Camshaft CS 299Qs10 .900 Base

Starting with a .900-inch base circle diameter, this COMP Cams camshaft is designed for applications where additional clearance is needed for longer stroke crankshafts, often found in stroker engines. This specific design is well-suited for larger displacement street to street/strip small block Chevy engines that have been upgraded with good cylinder heads. It’s important to note that this camshaft requires upgraded valve train components and aftermarket cylinder heads to perform as intended.

What sets this camshaft apart is its unique 4-Pattern lobe design, a technology borrowed from NASCAR racing. Unlike conventional camshafts that use a single intake and exhaust lobe profile, this one features two distinct intake and two distinct exhaust lobe profiles. This allows for optimized valve events tailored to the varying runner lengths found in typical V8 intake manifolds, where outboard runners are longer than inboard ones. By precisely timing when the valves open and close for each cylinder bank, this design helps balance the air/fuel mixture, leading to a significant increase in the area under the power curve and improved high-RPM stability. COMP Cams CNC-machines these camshafts from steel billet cores, ensuring a well-built and durable component. The tight lobe separation angle contributes to both strong performance and a desirable throaty exhaust note.

This camshaft fits a wide range of Chevrolet Small Block engines from 1958 to 2002, including popular models like the Camaro, Corvette, and C10 trucks. However, it's crucial to confirm your specific engine block's compatibility, as factory roller lifter provisions were gradually introduced from the mid-80s onward. You may need to check your intake manifold or timing cover to verify if your block is a factory roller or flat tappet design. Additionally, this camshaft is optimized for use with melanized or nitrided distributor gears; using cast or steel gears without similar surface treatments will void the warranty.
