Ignition Contact Set (Points) Guide for 1946-1954 Dodge Custom
Keep your classic Dodge running strong by understanding this critical ignition part.
- The ignition contact set (points) is a routine maintenance part on a 1946-1954 Dodge Custom.
- Symptoms of failure include no-start conditions, rough running, and poor engine performance.
- Setting the correct point gap with a feeler gauge during installation is critical for the engine to run properly.
- Standard Ignition is a reliable and widely available aftermarket brand for this component.
Symptoms of a Failing Ignition Contact Set
Ignition points are wear-and-tear items that need regular service. When they start to fail, you'll notice distinct problems with how your Dodge runs. The contact surfaces can burn or pit, and the rubbing block that rides on the distributor cam can wear down, causing the timing to be off.
Common Failure Symptoms:
- Engine Won't Start: The engine may crank over but fail to fire up because the points aren't triggering the spark correctly.
- Rough Running and Misfiring: Worn or improperly gapped points can cause the engine to run erratically, shake, and misfire at idle or during acceleration.
- Backfiring: Incorrect timing from bad points can cause the engine to backfire through the carburetor or exhaust.
- Poor Performance: You might notice the car feels sluggish or stutters under load as the worn points fail to deliver a consistent spark.
Choosing the Right Aftermarket Ignition Points
For a 1946-1954 Dodge Custom, finding new original equipment (OEM) parts is nearly impossible. The market is served almost exclusively by aftermarket manufacturers. Fortunately, brands like Standard Motor Products have been making ignition components for decades and are a reliable choice for American-built classic cars.
Brand Quality: Standard Ignition
Standard Motor Products (SMP) is a well-known and long-standing brand in the auto parts industry. For vintage American applications like the Dodge Custom, their quality is generally considered very good. Since points and condensers are a lower volume part today, consistency can sometimes vary, but Standard remains a go-to option for restorers and mechanics. When performing this repair, it is highly recommended to also replace the condenser, as a failing condenser can cause new points to burn out very quickly.
Pro Tip: When you replace your ignition points, also replace the condenser and rotor inside the distributor cap. These are inexpensive parts that wear together. Also, apply a small amount of distributor cam lube to the rubbing block on the new points to ensure a long service life.
Typical Replacement Costs
Replacing the ignition contact set is an affordable and common tune-up procedure for your classic Dodge.
| Part Type | Price Range |
|---|---|
| New Aftermarket (Standard Ignition) | $21.53 - $28.25 |
| Shop Labor | $100 - $180 |
Frequently Asked Questions (FAQ)
What exactly are ignition points?
Ignition points are a set of electrical contacts that act as a mechanical switch inside the distributor. They control the timing of the spark by switching the ignition coil on and off. 🎬 Watch this guide on how points ignition systems work and troubleshoot. This system was used in most cars until the mid-1970s, when electronic ignition became common.
How often should I replace the points on my Dodge Custom?
For a classic car, ignition points should be inspected annually and replaced as part of a regular tune-up, typically every 10,000 to 20,000 miles, or if you notice any running issues. Since these cars are often driven less, it's good practice to check them each spring.
What is the "point gap" and why is it important?
The "point gap" is the maximum distance the points open. This gap is critical and must be set with a feeler gauge during installation. An incorrect gap changes the "dwell angle"—the amount of time the points are closed—which affects coil saturation and ignition timing, leading to poor engine performance.
Can I upgrade to an electronic ignition?
Yes, many owners of classic cars choose to replace the points and condenser system with a modern electronic ignition conversion kit. These kits fit inside the original distributor and offer increased reliability, less maintenance, and a more consistent spark. However, a properly maintained points system is very reliable and easy to fix on the roadside with simple tools.

Technical Specifications
The most critical specification is the point gap, which should be set according to the vehicle's service manual. A common setting for Mopar 6-cylinder engines of this era is between 0.018" and 0.022". Always verify with a manual for your specific year and distributor model.
