Ignition Contact Set Guide for the 1957-1965 Ford Custom
Keep your classic Ford running strong by understanding, diagnosing, and replacing your ignition points.
- The ignition contact set (points) is a regular maintenance item on a 1957-1965 Ford Custom and a common cause of running issues.
- Symptoms of failure include no-start, rough running, misfiring, and reduced power.
- Setting the correct point gap or dwell angle is critical for engine performance; using a feeler gauge is required and a dwell meter is recommended.
- Standard Ignition and Accel are both reputable aftermarket brands for this part.
Is Your Ignition Contact Set Failing?
On a classic car like the 1957-1965 Ford Custom, the ignition contact set is a normal wear-and-tear item that requires periodic replacement. The rubbing block that rides on the distributor cam wears down, and the electrical contacts can become burned, pitted, or misaligned over time. This wear leads to a weak, inconsistent spark, which is a very common cause of engine problems on these vintage vehicles. Fortunately, the system is simple and straightforward to fix.
Symptoms of a Bad Ignition Contact Set
If your points are failing, your car will usually let you know with clear signs. Look out for these common symptoms:
- Hard Starting or No-Start: The engine cranks but won't fire up. This is often the first and most obvious sign that the points can't create the spark needed for ignition.
- Engine Misfires and Rough Running: Worn points can cause intermittent spark, leading to a shaky or lumpy idle, stuttering during acceleration, and an overall lack of smoothness.
- Stalling: The engine may stall at low RPMs, like when you come to a stop. This happens because the weak spark can't consistently keep the engine running without momentum.
- Reduced Power: If the points deliver a weak or poorly timed spark, combustion is inefficient. You'll feel this as sluggish acceleration and a general lack of power.
Choosing the Right Aftermarket Ignition Contact Set
Original Ford (Motorcraft) ignition points for this era are no longer produced, making aftermarket parts the only viable option. For a stock 1957-1965 Ford Custom, both available brands offer reliable performance.
Brand Tiers:
- Standard Ignition (Standard Motor Products): A long-standing and trusted name in aftermarket parts, often considered an OE-quality replacement. Their "Blue Streak" line is marketed as a premium option with design improvements over original specs. For a daily driver or stock restoration, Standard is an excellent choice.
- Accel: Often viewed as a performance-oriented brand. Accel points sometimes feature a higher spring tension, which is designed to prevent "point bounce" at very high RPMs. While perfectly suitable for a stock engine, they are a popular choice for modified or high-performance applications.
Pro Tip: Replace as a Set
Always replace the ignition condenser when you replace the points. A failing condenser can quickly burn out a new set of points. Most contact sets are sold with a new condenser included.
Cost of Replacing an Ignition Contact Set (1957-1965 Ford Custom)

Frequently Asked Questions (FAQ)
How often should I replace my ignition points?
Ignition points are a regular maintenance item. While condensers can last around 20,000 miles, the points themselves often require checking and adjustment every 10,000-12,000 miles. It's good practice to inspect them annually and replace them if they show signs of pitting, burning, or excessive wear on the rubbing block.
What is the 'point gap' and why is it so important?
The point gap is the maximum distance the contacts open. This gap is critical and is set with a feeler gauge during installation. An incorrect gap changes the 'dwell angle'—the amount of time the points remain closed. This affects how much energy the coil can store and also alters ignition timing, leading to poor performance.
What tools do I need to replace my ignition points?
You will need basic hand tools like a screwdriver and wrenches to remove the distributor cap and the points themselves. To set the gap correctly, you will need a feeler gauge. For the most accurate tuning, a dwell meter is recommended to set the dwell angle precisely after setting the initial gap.
Should I convert my Ford Custom to electronic ignition?
Many owners of classic cars choose to replace the points and condenser system with an electronic ignition conversion kit (like Pertronix). These kits eliminate the need for regular point adjustment and can provide a more consistent spark. However, for owners who prefer originality or the simplicity of the mechanical system, high-quality aftermarket points remain a perfectly reliable option.
Technical Specifications
OEM Part Numbers: B7A-12171-A C2AZ-12171-A FAC-12171-A
The most critical specification is the point gap and the resulting dwell angle. These values vary by engine. For V8 engines (like the 292, 352, 390), the point gap is typically set to 0.017 inches, which should result in a dwell angle between 26 and 31 degrees. Always set the point gap first, then verify with a dwell meter if possible, as dwell is the more accurate measurement.
