Melling 24407 Class 4 High Performance Retro-Fit Hydraulic Roller Camshaft

The Melling 24407 is a Class 4 High Performance Retro-Fit Hydraulic Roller Camshaft engineered for Ford 302 and 351 Windsor engines. Built from billet steel, this aggressive grind is designed for builders who want a strong high-rpm powerband and that iconic rough, choppy idle sound associated with serious performance builds.

This cam delivers a 2,500–6,000 RPM powerband, making it equally at home on the street or at the strip. With 224 degrees of intake duration and 232 degrees of exhaust duration (measured at 0.050-inch lift), combined with 0.542-inch intake and 0.563-inch exhaust valve lift, the 24407 is purpose-built for mid-to-high RPM power production.

Key Features:

• Camshaft Type: Hydraulic Roller – Retro-Fit design for non-roller block applications
• Construction: Billet steel for superior strength and durability
• Intake Duration @ 0.050": 224 degrees
• Exhaust Duration @ 0.050": 232 degrees
• Intake Valve Lift: 0.542 inch
• Exhaust Valve Lift: 0.563 inch
• Power RPM Range: 2,500–6,000 RPM
• No Special Distributor Gear Required: Compatible with standard distributor gear – no bronze or melonized gear needed
• Produces a distinctive rough idle characteristic of high-performance builds

Important Notes:

• Produces a rough idle; will not generate sufficient vacuum to operate power brakes – best suited for manual transmission or automatic with a high-stall converter
• Not computer (ECU) compatible – intended for carbureted racing applications
• Not California CARB-compliant – intended for racing use only
• Always install new lifters when installing a new camshaft
• Use Melling MELL-LUBE engine assembly lube during installation to prevent scoring and galling at initial startup

The Melling 24407 retro-fit camshaft offers a straightforward path to a proven, aggressive hydraulic-roller valvetrain setup without the complications of needing specialty distributor components, making it an excellent choice for classic Ford 302 and 351W performance builds.
