GM Gen V (Gen 5) LT Stage 2.75 232/248 Positive-Displacement Blower Camshaft – .625"/.637" Lift – 116.5° LSA

Designed specifically for positive-displacement (PD) supercharged LT combinations, this Stage 2.75 232/248 camshaft is built to take advantage of the unique characteristics of Roots-style and TVS-style superchargers.

Featuring 232° intake / 248° exhaust duration at .050", .625" intake lift, .637" exhaust lift, and a 116.5° lobe separation angle, this profile is designed to provide excellent cylinder filling, strong midrange torque, and dependable high-RPM airflow while working with the increased cylinder pressure of a positive-displacement blower.

The 116.5° LSA produces a more aggressive idle and powerband than wider blower-cam profiles. The additional exhaust duration helps evacuate the increased exhaust volume produced under boost, making this cam an excellent choice for aggressive street/strip PD-supercharged LT combinations.

Built for Boost

The 232/248 duration, .625"/.637" lift, and 116.5° LSA combination is designed for aggressive Gen V LT street/strip performance, with particular emphasis on positive-displacement blower applications.

Pair this camshaft with a properly matched valve spring and retainer package for a complete performance valvetrain capable of supporting increased RPM and boost.

Professional installation and complete valvetrain-clearance checks are required. Verify piston-to-valve clearance, spring installed height, coil bind, retainer-to-seal clearance, and overall valvetrain compatibility for your specific engine combination before operation.
