This Ford Hydraulic Roller Retro-Fit Kit 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 ships complete with detailed instructions and all necessary hardware.
• Works on all Small Block Ford engines originally equipped with a flat tappet or roller cam
• When using this kit in a non-roller block, a small base circle retro-fit cam must be used to ensure the lifters will not expose oil hole or band out of the lifter bores
• Kit must be used with Part #851-16 lifters
