GPI SS4 Gen V LT1 Camshaft

The GPI SS4 is designed for builders looking to extract every ounce of performance from their naturally aspirated Gen V LT1. Engineered for aggressive street/strip and dedicated race applications, the SS4 delivers exceptional horsepower and torque while maintaining surprising street drivability for a camshaft of this caliber.

With the proper combination of cylinder heads, supporting modifications, and tuning, the SS4 has proven capable of powering 10-second quarter-mile LT1 combinations. This camshaft continues to pull hard to approximately 7,200 RPM, making it an excellent choice for enthusiasts chasing maximum naturally aspirated performance.

For automatic transmission applications, a 4,000 RPM or higher torque converter is required to achieve the camshaft’s full potential.
