The COMP Cams CS 287Tk‑R6 camshaft is aimed at 377–406 late‑model engines with good heads, intake and a 1.6:1 rocker ratio. It’s specified for configurations where those supporting components are present to realize intended torque and power delivery for short‑track performance. Important: 1955–57 small‑block Chevys that have an oiling groove in the rear journal will not accept the listed cams—contact us for a grooved alternative.
