FMBP 40400 Engine Timing Set

Performance Timing Chain Kit

This Melling engine timing set is built for rebuilds that need a performance-oriented timing solution with matched sprockets and a double roller chain. Part number 40400 is listed for a wide range of Chevrolet and GMC applications, including many engines without a factory roller camshaft or balance shaft.

• Double roller timing chain for performance use
• Keyway-adjustable design for timing correction
• Cast iron camshaft sprocket for durable service
• Sprockets included for a complete timing set
• Maximum camshaft advance and retard of 2.0 degrees

Application Details

Part number 40400 is a performance-grade timing chain kit from Melling’s Performance line. It is intended for engine rebuilds where accurate valve timing and matched components matter, and it cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Compatible With Chevrolet Camaro, Chevrolet Corvette, GMC Yukon, and many other Chevrolet and GMC V8 applications listed in the fitment data, this timing set is also shown for classic and late-model trucks, vans, and performance cars. The adjustable keyway helps fine-tune cam timing within the listed advance and retard range.

Common Uses

• Restoring worn timing components during an engine rebuild
• Replacing stretched chain or worn sprockets
• Correcting cam timing during performance setup
• Addressing timing noise from aged valve train parts
• Servicing engines that require a non-roller or balance-shaft-specific timing set

Installation Notes

Verify engine configuration before ordering, especially whether the application uses a factory roller camshaft or balance shaft. Fitment includes many Chevrolet and GMC models such as Chevrolet Camaro, Chevrolet Corvette, and GMC Yukon, with notes that vary by engine setup and center distance. Confirm sprocket alignment and timing marks during installation, and follow the engine builder’s service procedure for cam timing adjustment.
