The COMP Cams XFI AFM camshaft delivers outstanding top-end power for modified LT1 applications with AFM enabled, with only slight low-end losses when properly programmed. Built to work with direct injection, VVT and AFM lifters, these cams use multiple lobe profiles for AFM compatibility and across-the-board gains. Installation requires the COMP Phaser Limiter Kit (part 5456) and PCM tuning.
