• Andrews
• These bolt-in type cams are designed for 88ci Twin Cam engines with stock compression using hydraulic lifters
• They are compatible with carbureted or fuel injected models. Note: EI models will require re-calibration of the ECU
• Reduced maintenance (no plastic chain guides or tension shoes to wear and contaminate your engine oil or clog oil passages)
• Cam timing remains constant. All drive and cam gears utilize a light press fit (gear lash) thus eliminating any chain stretch
• Bearing loads are reduced. No spring loaded chain tensioners are used (which can rob up to 4 horsepower)
• Critical sprocket alignment is unnecessary
• Can be used with the OEM non-adjustable pushrods, but we suggest using our adjustable pushrods found in the Engine Section to ease installation and eliminate the need to remove the fuel tank and rocker covers
• See General Merchandise Section for the required installation tools
• Includes instructions
