Key Features

• Billet camshaft sprocket for street performance use
• Billet crankshaft sprocket with nine keyways for +/- 8 degrees of adjustability
• Heat-treated crank sprocket for added durability
• TRUE roller chain with 0.250-inch roller diameter to reduce friction
• Fits a wide range of Ford and Mercury applications from 1963-1977

Detailed Description

This Cloyes engine timing set, part number 9-3508X9, is engineered for classic Ford and Mercury engines where cam timing adjustment matters. The nine-keyway crank sprocket gives installers a practical way to fine-tune timing, while the roller chain design helps reduce friction in the valvetrain drive. The street billet construction and heat-treated sprocket support performance use in applications such as Ford Mustang, Ford Galaxie, and Mercury Cougar.

Fitment includes 1963-1977 Ford and Mercury models such as Mustang, Torino, Fairlane, Thunderbird, Ranchero, GT40, Cougar, Comet, Monterey, and others listed in the application data. This part cross-references 93508X9 for the same application.

What It Is Used For

• Correcting cam timing during engine assembly or rebuild
• Adjusting timing advance or retard for performance tuning
• Replacing worn timing components that can affect valve timing accuracy
• Reducing friction in the timing drive with a roller chain design
• Supporting street performance builds that use a billet timing set

Installation Notes and Tips

Verify engine application and timing cover clearance before installation. The fitment notes indicate this design does not require a spacer on the cam nose because the spacer is cast into the sprocket hub. Confirm the selected keyway position during setup to achieve the desired timing change. Fits 1967-1970 Ford Mustang, N/A; Fits 1967-1970 Mercury Cougar, N/A; Fits 1963-1971 Ford Galaxie 500, N/A.
