GPI LT1 / LT4 / L86 / L97 / L83 / L84 Blower Cam - LT PD2 (2016 - 2024 Camaro | 2014 - 2019 C7 Corvette) - LTPD2
High-Power Positive Displacement Blower Cam for Aggressive LT Builds
The GPI LT PD2 Blower Cam is engineered for enthusiasts pushing their LT1, LT4, L86, L97, L83, and L84 engines harder under a positive displacement supercharger. This cam takes the proven PD1 formula and elevates it with stronger mid-range pull and 10 - 15 HP more up top, making it ideal for street/strip cars and high-output trucks.
Whether you're running a Whipple, Magnuson, Edelbrock, or LT4 blower, the PD2 delivers harder acceleration, more airflow at higher RPM, and the durability needed for long-term boosted performance.

FAQs
Do I need a converter upgrade for the LT PD2?
A converter upgrade is strongly recommended: 2500+ RPM for 6.2L and 3000+ RPM for 5.3L engines. While 6.2L can technically run a stock converter, performance is significantly better with an upgraded unit.
How much more power does the PD2 make over the PD1?
Expect 10 - 15 additional horsepower up top thanks to more aggressive duration and blower-optimized timing.
