Ford V8 302 351 Cleveland Hydraulic Camshaft 212/217@50

Ford V8 302/351 Cleveland Hydraulic Camshaft — 212/217 @.050" with 110° LSA

Engineered for street-driven Ford V8s, this hydraulic flat tappet camshaft is a purposeful upgrade for 302 and 351 Cleveland blocks. It delivers a smooth, medium-idle idle and a strong mid-range pull without sacrificing drivability, making it a practical choice for daily drivers and weekend cruisers alike.

Why this cam suits your Ford V8

• Mid-range power that improves real-world performance from 1,800 to 5,000 RPM, matching typical street driving and throttle response.
• Hydraulic lifters reduce maintenance and eliminate lash adjustments, helping you enjoy a steady idle and reliable operation.
• With a 110° lobe separation angle (LSA), the cam maintains vacuum stability and smooth idle while still delivering torque when you roll into the throttle.
• Small, steady duration figures—Advertised: 272° IN / 283° EX; with 1.73 rockers: 212° IN / 217° EX @.050"—provide a balanced blend of low-end responsiveness and usable top-end power.
• Lash measured hot: IN.498" / EX.507" to ensure accurate valve events under operating conditions.

Performance and installation notes

This cam delivers a confident, street-friendly idle with a broad low-to-mid range torque curve. To maximize its potential, pair it with a properly tuned carburetor and equal-length headers, along with performance springs and retainers as specified. If you’re targeting stronger pulling power in the 2,000–4,500 RPM window without sacrificing idle quality, this profile is a practical, reliable choice.

What you need to know before buying

• Designed for mild street use—expect a noticeable improvement in throttle response and mid-range torque over stock cams in compatible Ford V8 builds.
• Ensure your ignition and fuel system are in good condition to support the cam’s RPM range and to avoid drivability issues.
• Adhere to the installation notes: use performance springs and retainers, and consider boosting the carburation and exhaust flow to fully exploit the cam’s characteristics.
