The Benchmark Positive Displacement Blower Cam for 5.3L L83 Engines
The GPI L83 PD1 Blower Cam is the premier camshaft upgrade for 5.3L L83 engines equipped with a positive displacement supercharger. Designed specifically for PD blower applications - including Whipple, Magnuson, Edelbrock, and LT4-style superchargers - this cam delivers exceptional torque, smooth idle quality, improved throttle response, and excellent top-end pull, all while maintaining near-stock drivability.
Proven across countless GM trucks and SUVs, as well as PD-converted 6th Gen Camaro and C7 Corvette swaps, this cam has earned its reputation as the best PD blower cam for the L83 platform.

The L83 PD1 is optimized for street use and works exceptionally well with a stock torque converter. It features a smooth lobe design for quiet valvetrain operation, consistent long-term durability, and a stable ~725 RPM idle - ideal for truck applications and daily-driven boosted builds.
