To make the most power from your engine, you need to optimize the air ingested and captured by avoiding valves closing too soon or too late. COMP Cams 4-pattern hydraulic roller camshafts are the first series of cams designed to accommodate a difference in runner length and avoid valves closing at the wrong times. Any conventional center-layout single throttle body or carbureted V8 intake manifold features longer outboard runners and shorter inboard runners, meaning that each valve event should occur at a different moment. COMP Cams has designed a series of cams that optimizes valve events and features a large increase in both area under the curve and stability at high rpm. They feature four different lobe patterns with one intake and exhaust design for outboard runners and another intake and exhaust design for the inboard runners. While the four central cylinders are all the same grinds, the outboard exhaust openings are two degrees earlier, with outboard intake closings coming two degrees later. NASCAR has been utilizing this technology for years. COMP Cams is now applying this same knowledge in street vehicles to balance air/fuel ratio per cylinder. These cams are CNC-ground from steel billet cores. They feature cast iron distributor gears and utilize a series of lobes with over .600 in. valve lift and stability up to 7,500 rpm, all while providing more consistent cylinder to cylinder torque. They also feature tight lobe separation for both excellent power and a throaty sound. Designed for small block Chevy, big block Chevy, and small block Ford carbureted or fuel injected applications, the design is exclusive and unique to COMP Cams.
