COMP Retro-Fit Hydraulic Roller Installation Kit (CO31-1000)

Part no. CO31-1000 contains the pieces required to install our complete line of hydraulic roller cams in 302, 351W, 351C and 351M-400 Ford engines that did not come with an OEM hydraulic roller cam. This kit works on all small block engines originally equipped with either a flat tappet or a roller cam. When using this kit in a non-roller block, it is necessary to use a small base circle cam to ensure the lifters will not rise out of the lifter bores. This kit must be used with Part no. CO851-16 lifters. Comes complete with detailed instructions and all necessary hardware.
