GPI LT1 / LT4 / L86 / L97 / L83 / L84 Blower Cam - LT PD1 (2016 - 2024 Camaro | 2014 - 2019 C7 Corvette) - LTPD1
The Industry-Leading Positive Displacement Blower Cam for LT Engines
The GPI LT PD1 Blower Cam is widely regarded as the best-performing camshaft for LT1, LT4, L86, L97, L83, and L84 engines running a positive displacement supercharger. Proven across 6th Gen Camaros, C7 Corvettes, and GM trucks, this cam delivers exceptional torque, stable idle performance, and strong power all the way through 6400 RPM. If you're adding a Whipple, Magnuson, Edelbrock, or LT4 blower, this is the cam designed specifically for you.
With smooth lobes, stable valvetrain dynamics, and compatibility with the stock torque converter, the LT PD1 provides uncompromising performance without sacrificing drivability - making it the benchmark blower cam on the market.
