FMBP 40405 Engine Timing Set

Performance timing set for Ford V8 applications

This Melling engine timing set is built for performance-oriented rebuilds that need matched timing components in one package. It uses a double roller timing chain, cast iron camshaft sprocket, and an adjustable keyway to fine-tune cam timing within the application.

• Double roller timing chain for stable chain engagement
• Cast iron camshaft sprocket for durable gear construction
• Adjustable keyway with up to 2.0 degrees advance or retard at the camshaft
• Sprockets included for a complete timing component set
• Performance grade design for rebuild and upgrade use

Built for rebuild accuracy

Melling timing chain kits are offered as an efficient, economical way to replace the timing components needed during an engine rebuild. This kit follows that approach with matched chain and sprocket components, and it is part of Melling’s Performance line for buyers looking for a performance-focused timing solution. Part number 40405 is listed for a wide range of Ford, Lincoln, and Mercury V8 applications, including Ford F-100, Ford F-150, and Mercury Cougar models with the specified 5.044-inch center distance.

This part cross-references Monroe Shocks & Struts (e.g., 9-1121, 220-3121) for the same application.

Common issues this set addresses

• Worn timing chain stretch that affects cam timing
• Damaged or tired sprocket teeth in the timing drive
• Need for cam timing adjustment during engine rebuilds
• Replacing mismatched timing components with a matched set
• Performance rebuilds that require a double roller chain setup

Installation notes and tips

Verify engine application, center distance, and timing cover clearance before installation. The adjustable keyway allows timing changes within the listed range, so cam timing should be checked during assembly rather than assumed from the previous setup. Confirm that the timing components match the engine’s rebuild specifications before final assembly.

Quality assurance

Melling manufactures timing chain kits with quality materials and workmanship, and this Performance series kit is built to support performance-level service requirements. Part number 40405 is engineered as a matched timing component set for the listed applications.
