Description

The 2014+ C7 Corvette Stingray out of the box has some very high flowing heads with approximately 295 cfm and the AFM kit keeps the environment conscious happy; however for some of us, this is just isn’t enough..  We need more flow, a more aggressive cam, and want to see over 500 naturally aspirated rear wheel HP!  

Increase TQ & HP Throughout RPM Range with XFI™ AFM Cams for GM Gen V

Revolutionary GM Gen V Camshafts from COMP Cams® are designed to work with the direct injection, VVT (Variable Valve Timing) and AFM (Active Fuel Management) lifters featured in GM’s Gen V (LT1/L83/L86) V8 engine. This means that these XFI™ series hydraulic roller cams allow users to leverage the OE technology for performance gains. Gen V Cams feature four different lobe profiles to both create AFM compatibility and optimize intake and exhaust valve opening/closing events. COMP Cams® GM Gen V Camshafts increase torque and horsepower throughout the entire RPM range, while providing excellent responsiveness and mid-range power over stock for across-the-board gains.

These cams must have the COMP® Phaser Limiter Kit (Part #5456), which limits the range of camshaft movement from 62 to 22 crank degrees thus requiring PCM tuning. COMP Cams® GM Gen V Camshafts are available for stock to highly modified applications.
