BBC Blower Camshaft 290DS-14

The COMP CAMS BBC Blower Camshaft 290DS-14 is a specialized billet cam core engineered for big-block Chevy engines running supercharger or blower setups. This cam is built for enthusiasts and professional builders who demand aggressive valve timing and maximum airflow capability on forced-induction platforms. The 290DS-14 designation reflects its lift and duration specifications, optimized to work with the pressure and flow characteristics unique to blower-equipped BBC powerplants.

COMP CAMS engineered this blower camshaft with precision lobes designed to manage the extreme cylinder pressures and scavenging demands of supercharged big-block applications. The billet construction ensures dimensional consistency and durability under sustained high-RPM boost conditions where cast cam lobes often fail. The 290 designation indicates aggressive duration at 0.050-inch lift, while the DS profile (dual-spring compatible) allows this cam to work with both factory and aftermarket valvetrain components common in BBC restorations and performance builds.

This camshaft is ideal for BBC stroker engines, pro-street big-blocks, and full-race supercharged builds requiring a proven, track-tested lobe profile. Installation requires proper valvetrain clearance verification, as aggressive blower cams demand attention to pushrod length, rocker arm geometry, and piston-to-valve clearance. Weighing 10.35 lbs and engineered to COMP CAMS' exacting tolerances, the 290DS-14 pairs seamlessly with billet timing chains, upgraded lifters, and high-flow cylinder heads to unlock the full potential of forced-induction big-block Chevy platforms.
