Duration @ .050 = 216 Intake – 228 Exhaust
Valve Lift with stock 1.8 rocker = .572 intake – .529 exhaust
Gen V Camshafts (LT1/L83/L86) from COMP Cams® are designed to work with the direct injection (DI), variable valve timing (VVT) and Active Fuel Management (AFM) lifters featured in GM’s new Gen V V8 engine. This means that these new XFI™ series hydraulic roller cams allow users to leverage OE technology for performance gains. Gen V Cams feature four different lobe profiles to not only allow AFM-lifter compatibility, but also to optimize intake and exhaust valve opening/closing events. COMP Cams® GM Gen V Camshafts also increase torque and power throughout the entire RPM range, while providing excellent responsiveness and mid-range power over stock for across-the-board gains. The cams must have the COMP® Phaser Limiter Kit (Part # 5456), which limits the range of camshaft movement from 62 to 22 crank degrees. Thus they require VVT program tuning.
