Choosing the Right Engine Timing Set for Your 1964-1971 Ford F-350
Keep your classic Ford truck's engine running strong by understanding its most critical maintenance part.
- The original timing gears on V8 engines used failure-prone nylon teeth; any aftermarket all-metal set is a significant upgrade.
- For inline-six engines, check if the distributor rotor spins while cranking; if not, the timing gears have likely failed.
- Replacing the water pump at the same time is highly recommended to save on future labor costs.
- A standard replacement set from Melling or Cloyes is excellent for stock trucks, while performance brands offer added durability for heavy use.
Is Your F-350's Timing Set Due for Replacement?
If your 1964-1971 Ford F-350 still has its original timing set, it's living on borrowed time. The main issue, especially on the popular FE V8 engines (like the 360 and 390), was the original camshaft gear. Ford used a gear with nylon-coated teeth to make the engine quieter. After decades of heat and age, this nylon becomes brittle and breaks off, which can cause the timing chain to slip or break. This can leave you stranded or even cause engine damage.
Aftermarket timing sets are a major upgrade because they use all-metal gears (cast iron or steel) that won't break apart like the old nylon ones. This is one area where aftermarket quality is significantly better than the original OEM design for these classic trucks.
Symptoms of a Failing Timing Set
A worn or failing timing set can show several signs. Don't ignore them, as a complete failure is much more expensive to fix.
- Rattling Noise: A loose timing chain can slap against the inside of the metal timing cover, creating a rattling sound from the front of the engine, especially at idle or on startup.
- Engine Misfires or Rough Idle: If the chain has stretched or "jumped" a tooth on the gear, the valve timing will be incorrect. This leads to a rough-running engine, poor performance, and bad fuel economy.
- Engine Won't Start: If the chain breaks or the gears strip completely, the camshaft will stop turning. The engine will crank over but will not start. For inline-six engines, a quick test is to remove the distributor cap and see if the rotor spins when you crank the engine; if it doesn't, the timing gears are stripped.
- Metal Shavings in Oil: When the gears and chain wear, tiny metal pieces can end up in the engine oil. You might see these during an oil change.
V8 vs. Inline-Six Engines
It's important to know which engine you have. The Ford FE V8 engines (352, 360, 390) use a timing chain and sprocket set. The Ford inline-six engines (240, 300) use a set of two direct-meshing timing gears. The parts are not interchangeable. This guide focuses primarily on the more common chain-driven V8s, but the failure symptoms are similar for both.
Choosing Your Aftermarket Timing Set
Not all aftermarket timing sets are the same. They generally fall into two categories for your F-350.
Standard Replacement Brands
These are great for a daily driver or stock restoration. They are a direct replacement and a solid upgrade over the original nylon-toothed parts.
- Melling: A well-respected brand for engine components. They offer durable, all-metal timing sets that are known for their quality and fit. Many mechanics trust Melling for reliable, stock-level repairs.
- Cloyes: Another huge name in timing components. They offer a wide range of products from standard to high performance. For a stock engine, their standard replacement sets are a cost-effective and reliable choice.
- INA: While a major OEM supplier for many modern cars, INA is not a common brand found in the classic Ford truck community for this specific part.
Performance & Heavy-Duty Brands
If you use your truck for towing, hauling, or have a modified engine, stepping up to a performance set is a wise investment. These often feature stronger "double roller" chains and billet steel gears.
- Melling Select Performance: Melling's high-performance line offers increased durability for engines that work hard.
- Edelbrock: Known for performance parts, their timing sets are built to handle higher horsepower and stress. They often feature double-roller chains and multiple keyways for adjusting cam timing.
- Ford Performance: These sets are designed for durability and performance. They often feature multi-keyway crank sprockets, allowing for precise camshaft timing adjustments, which is a plus for performance builds.
Pro Tip: For most owners, a standard replacement set from Melling or Cloyes is more than enough. If you are rebuilding the engine or want extra peace of mind, a double-roller set from Ford Performance or Edelbrock is an excellent, durable upgrade.
Estimated Costs for Timing Set Replacement
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Timing Set | $40 - $65 |
| Shop Labor | $500 - $750 |
| Total Professional Installation | $540 - $815 |
Costs are estimates and can vary by location and shop. The job is often done at the same time as a water pump replacement to save on labor.
Frequently Asked Questions
Can I replace the timing set myself?
Yes, this is a common DIY job for those with some mechanical experience. It requires basic hand tools, a drain pan, and a harmonic balancer puller. The key is to be careful when sealing the new timing cover to the engine block and oil pan to prevent leaks.
Should I replace the water pump at the same time?
Yes, it is highly recommended. You have to remove the water pump to get to the timing cover anyway. Replacing it at the same time costs very little in extra labor and prevents you from having to do the job twice if the old water pump fails later.
What is a "double roller" chain?
A double roller chain is like a heavy-duty bicycle chain with two rows of rollers side-by-side. It is much stronger and less likely to stretch than a standard "silent" or link-type chain. It's a common feature on performance timing sets.
Do I need a set with multiple keyways?
For a stock engine, no. A standard, non-adjustable set is fine. Multi-keyway sprockets allow a mechanic to slightly advance or retard the camshaft timing to optimize engine performance. This is a feature mostly used by engine builders and performance enthusiasts.
Technical Specifications
Varies by engine. V8 models use a chain and sprocket set. Inline-6 models use a gear-to-gear set. Aftermarket V8 sets are available in standard link-type, single roller, and double roller chain configurations. Gears are typically cast iron or billet steel.
