COMP Cams 35-425-8 Xtreme Energy Hydraulic Roller Camshaft and Retro Fit Roller Lifters for Ford 289 302 351W — Retro-Fit Street/Strip Performance Cam — 230/236 @ .050", .513"/.529", 110° LSA

Upgrade your classic Ford engine to modern roller power with the COMP Cams 35-425-8 Xtreme Energy Hydraulic Roller Camshaft. Designed for retro-fitting non-roller 289, 302, and 351 Windsor blocks, this cam brings big torque, crisp throttle response, and a distinct lope to street and strip applications. With 230°/236° duration @ .050" lift, .513"/.529" valve lift, and a 110° lobe separation angle, the 35-425-8 cam delivers explosive mid-range power and strong top-end pull to 6,000 RPM. Expect a noticeable idle that sounds mean and turns heads while remaining street-friendly with proper gearing and compression. This grind is ideal for builds featuring performance heads, 9.5:1+ compression, headers, and aftermarket intake manifolds. It matches the early 351W and 5.0 H.O. firing order (1-3-7-2-6-5-4-8) for smooth engine operation and proper timing. Installation is straightforward with COMP Cams retro-fit link bar lifters (sold separately). Whether you’re reviving a classic Mustang, F-100, or Fairlane, the 35-425-8 adds that iconic COMP Cams sound and street authority—power you can feel and performance you can trust.
