BBC Hyd. Roller Cam

The BBC Hyd. Roller Cam by Howards Racing Components is a precision-engineered hydraulic roller camshaft designed specifically for big-block Chevrolet engine builds. This camshaft is ideal for those upgrading their BBC platform for street performance, drag racing, or other high-performance applications. It delivers the necessary valve actuation geometry to maximize power output and unlock the potential of cylinder heads.

Featuring a roller lifter design, this hydraulic roller cam eliminates friction losses that are common with flat-tappet cams, resulting in improved efficiency and reduced wear on valvetrain components. The camshaft profile is engineered to optimize valve overlap, duration, and lift characteristics, while the roller follower design ensures consistent lobe contact and minimizes side loading on cam lobes and lifter bores. Manufactured to strict tolerances from hardened steel with a specialized lobe coating, it is built to withstand high-load conditions.

This camshaft is particularly beneficial for builders targeting elevated compression ratios, cylinder head porting, or forced-induction setups where valvetrain stability is crucial. Its hydraulic design compensates for thermal expansion, making it a reliable choice for high-performance applications. Whether for street or strip use, this camshaft is designed to meet the demands of serious enthusiasts.
