Hydraulic Roller Camshaft Retro-Fit Kits
If you have a non-HO 5.0L or an engine that doesn't have all it's necessary parts and pieces for a factory style roller camshaft these kits offer you the components necessary for a roller camshaft and also includes your choice of a camshaft with increased lift and duration to match your application.
Note: This conversion kit will require drilling and tapping your lifter valley for installation of lifter tie bars. It is also requires use of a roller cam compatible distributor gear. Roller camshafts require higher spring pressures than flat tappet camshafts. Be sure to check for proper pushrod length. Kits fit 1985-01 302ci, 1994-97 351ci Windsor, 1996-04 SVO blocks & the new Ford Racing Boss 302 block.

Bring modern performance and reliability to your classic small-block Ford with Ford Performance Hydraulic Roller Retro-Fit Kits — the perfect upgrade for enthusiasts who want stronger midrange torque, smoother idle quality, and improved valve train durability without sacrificing street manners. These kits are designed to breathe new life into older 5.0-liter engines and other SBF applications by replacing worn flat tappet components with precision-engineered hydraulic roller hardware.
One of the highlights of this upgrade is how it transforms your retro 5.0 setup. By using contemporary roller lifters and a matching cam profile, you’ll experience more responsive throttle behavior and reduced friction compared to outdated flat tappet designs. That means improved efficiency during daily driving, better throttle response on the street, and greater overall reliability — especially in high-vacuum cruising and spirited driving situations.
At the heart of these kits lies an SBF hydraulic roller cam that’s been carefully matched to Ford’s roller lifters and valvetrain geometry. This ensures optimal timing accuracy and consistent performance across the entire RPM range. The hydraulic design also reduces maintenance demands and helps extend component life by minimizing wear on cam lobes and lifters, making it a smart investment for enthusiasts focused on longevity.
Installation is straightforward for experienced builders and professional shops alike, with engineered compatibility for popular 302, 289, and related small-block platforms. Whether you’re refreshing an older engine or building a fresh performance mill, the included SBF hydraulic roller camshaft kit hardware helps simplify your upgrade and maximize results.
For classic Ford builders seeking modern valvetrain performance and enhanced drivability, these hydraulic roller retro-fit kits offer a well-balanced blend of power, smoothness, and durability — making them an essential upgrade for any serious small-block project.
