The BBC Xtreme Hydraulic Roller Cam XR288HR from COMP CAMS is designed for serious big-block Chevrolet engine builders who seek a balance of aggressive performance and streetability. This hydraulic roller camshaft is engineered to provide the necessary valve lift and duration for optimal high-RPM breathing while ensuring the reliability that hydraulic actuation offers.
The XR288HR features precision-ground lobes that enhance valve overlap, intake velocity, and scavenging efficiency throughout the RPM range. By utilizing roller followers, this camshaft reduces friction losses compared to traditional flat-tappet designs, resulting in improved horsepower and fuel economy at part throttle. The hydraulic roller technology simplifies installation and maintenance, making it a practical choice for builders.
Ideal for various big-block platforms, including BBC 366, 396, 402, 427, 454, and 502 displacements, the XR288HR is compatible with both factory and aftermarket cylinder heads and intake manifolds. Builders will appreciate the tight manufacturing tolerances that ensure consistent performance across cylinders, which is crucial for achieving repeatable dyno results or track times.
