Engine Timing Set Replacement for the 1959-1960 Dodge Truck
Keep your classic Dodge engine's heartbeat steady and strong with the right timing components.
- You MUST correctly identify your engine (Flathead 6, Slant-6, or 318 Poly V8) before ordering a part.
- For this vintage truck, aftermarket parts are the standard. The choice is between a quality stock replacement (Cloyes) or a heavy-duty performance upgrade (Edelbrock).
- Symptoms like engine rattle or rough running should be addressed immediately to prevent severe engine damage.
- It is highly recommended to also replace the water pump, front crank seal, and gaskets at the same time to save on future labor.
Signs of a Failing Timing Set
After decades of service, the original timing set in your Dodge truck can wear out. A stretched chain or worn gears can cause serious issues. Watch for these common symptoms:
- Engine Rattle: A rattling or clattering noise from the front of the engine, especially at idle or on startup, is a classic sign of a loose timing chain slapping against the timing cover.
- Poor Engine Performance: If the chain has stretched or jumped a tooth, the cam timing will be off. This can lead to engine misfires, rough idling, a loss of power, and poor acceleration.
- Metal Shavings in Oil: During an oil change, finding small, shiny metal shavings in the drained oil or filter can be a sign that the timing chain and gears are wearing down and shedding material.
- Engine Won't Start: In a worst-case scenario, a broken timing chain will prevent the engine from starting at all. This can cause major internal engine damage if it breaks while running.
Choosing the Right Aftermarket Timing Set
For a vehicle of this age, finding a "new" OEM part from a dealer is not possible. The market consists of New Old Stock (NOS) parts at collector prices or, more practically, new aftermarket sets. Aftermarket quality is excellent and offers options for any need.
Match the Part to Your Engine!
The single most important step is to correctly identify your engine. The 1959-1960 Dodge trucks came with several options, and the timing sets are not interchangeable. You likely have one of these:
- 230ci Flathead 6: An older design, often using fiber or steel gears instead of a chain.
- 318ci "Poly" V8: A common V8 option for these years that uses a timing chain and sprocket set.
- 225ci "Slant-6": Introduced around 1960, this legendary engine also uses a timing chain and sprockets.
Ordering the wrong set is the most common mistake. Confirm your engine before you buy.
Brand Quality Tiers
Your choice comes down to standard replacement versus a performance upgrade.
Standard Replacement: Cloyes
Cloyes is a well-respected brand known for making high-quality timing components that meet or exceed original factory specifications. For a stock truck or a daily driver, a Cloyes set is an excellent, reliable choice that will restore original performance and quiet operation. They are considered a top name for standard replacement parts.
Performance Upgrade: Edelbrock
Edelbrock is a famous name in performance parts. Their timing sets often feature a "true roller" chain, which is stronger and creates less friction than a standard chain. These sets are built with high-quality steel for durability, making them ideal for modified engines, heavy-duty use, or for owners who simply want the strongest components available. Many Edelbrock sets also offer multiple keyways on the crank sprocket, allowing for advanced or retarded cam timing for performance tuning.

Frequently Asked Questions
How do I know which engine my truck has?
Check the data plate on the vehicle, usually on the driver's side door jamb or firewall. You can also identify it visually. The Slant-6 is famous for being physically tilted to one side. The Poly V8 has distinct, scalloped valve covers. The Flathead 6 has a very simple, flat cylinder head with the spark plugs on top. If unsure, consult a mechanic or a vintage Dodge truck forum.
Is a double-roller chain worth the extra cost?
For most stock applications, a standard-style chain from a quality brand like Cloyes is perfectly adequate. A double-roller chain, like those from Edelbrock, offers extra strength and durability, which is good insurance for a high-performance engine or one that will be worked hard.
Should I replace anything else at the same time?
Yes. Since you have to remove the water pump and timing cover to access the timing set, it is the perfect time to replace the water pump, timing cover gasket, and the front crankshaft seal. This prevents you from having to do the same labor all over again if one of those parts fails soon after.
Are these interference engines?
It depends on the specific engine and if it has been modified. An interference engine is one where the valves and pistons can collide if the timing is lost. Because of the risk, any symptom of a bad timing chain should be addressed immediately to prevent a potential chain break that could destroy the engine.
Technical Specifications
Timing sets vary by engine. The 230ci Flathead I6 may use gears. The 225ci Slant-6 and 318ci Poly V8 use a timing chain and sprocket set. Chain and gear tooth counts are specific to each engine family.
