MSD 8581 Ford 351C-460 Bronze Distributor Gear AMPCO 45

The MSD 8581 is a bronze distributor gear engineered for Ford big-block and Cleveland-family engines running camshafts that require a bronze gear interface. Machined from AMPCO 45 aluminum bronze with 5% nickel content, this gear delivers the material compatibility needed to protect performance roller and billet camshafts that cannot be paired with standard iron or steel distributor gears.

Key Features:

• Machined from AMPCO 45 aluminum bronze containing 5% nickel for superior material compatibility with specialty camshafts
• High-strength gear teeth resist wear even under heavy loads from high-volume oil pumps
• Bronze construction is gentler on cam lobes than steel or iron gears, reducing camshaft wear
• 0.530-inch shaft diameter fits Ford 351C, 351M, 400, 429, 460, and FE block engines
• Kit includes a rolled roll pin for excellent installation strength
• Includes gear break-in lubricant for proper initial wear-in
• No additional drilling required for installation
• Sold individually
