GPI LT1 / LT4 / L86 / L97 / L83 / L84 Blower Cam - L83 PD3 (2016 - 2024 Camaro | 2014 - 2019 C7 Corvette) - L83PD3
The Most Aggressive Positive Displacement Blower Cam for the 5.3L L83
The GPI L83 PD3 Blower Cam is the hardest-hitting PD camshaft available for the 5.3L L83 platform. Designed for hardcore street/strip builds, the PD3 offers significantly more torque and horsepower than the PD1 and PD2 grinds, carrying power all the way to a roaring 7000 RPM. If your boosted L83 is running out of cam - this is the fix.
Track-tested, developed, and proven, the PD3 is engineered for positive displacement blower systems including Whipple, Magnuson, Edelbrock, and LT4-style superchargers. When you're ready for maximum airflow under boost without compromising valvetrain reliability, the PD3 is the go-to heavy hitter.
Aggressive L83 Blower Cam Specs
- Duration (Int/Exh): 224 / 240
- Valve Lift (Int/Exh): .630" / .612"

Engineered for Maximum Power Under Boost
This cam was built for one purpose: big power in PD-blown 5.3L engines. Compared to the PD1 and PD2, the PD3 dramatically increases airflow, mid-range punch, and top-end horsepower - making it the ideal choice for lightweight builds, drag applications, and high-RPM street animals.
Because of the aggressive intake and exhaust profiles, the PD3 requires a 3000+ RPM torque converter to operate correctly in trucks and swap platforms.
