- Always replace the condenser at the same time as the points; they are often sold together in a kit.
- Symptoms like rough running, stalling, or a no-start condition often point to failing ignition points.
- High-quality aftermarket brands like Accel and Standard Ignition are the go-to choices for this part.
Understanding the Ignition System in Your Classic Biscayne
The 1958-1962 Chevrolet Biscayne uses a traditional points-and-condenser ignition system. Unlike modern cars with electronic ignition, your Biscayne relies on this mechanical set of contacts to fire the spark plugs. The ignition contact set, or points, are a wear item, meaning they require periodic replacement as part of regular maintenance, typically every 10,000 to 15,000 miles. Over time, the constant opening and closing causes the contact surfaces to wear, burn, or pit, affecting engine performance.
Symptoms of a Failing Ignition Contact Set
A failing set of points will give you clear signs that it's time for a replacement. Because they wear out gradually, you will usually notice a decline in performance before a complete failure. Common symptoms include:
- Engine Misfires or Rough Running: Worn or improperly gapped points cause weak or inconsistent sparks, leading to a rough idle and hesitation during acceleration.
- Difficulty Starting: If the points are badly burned or misaligned, they can't create the strong spark needed to start the engine easily.
- Engine Stalling: Poor contact between the points can cause the engine to stall, especially at idle or when coming to a stop.
- No-Start Condition: In a complete failure, the points may be stuck open or closed, preventing any spark from being generated. The engine will crank but will not start.
Choosing the Right Aftermarket Ignition Contact Set
For a vehicle like the 1958-1962 Biscayne, new OEM parts from Chevrolet are no longer produced. The classic car community relies on high-quality aftermarket manufacturers that specialize in these components. Aftermarket is the standard, and excellent options are available.
When shopping for a replacement, you'll find reliable brands that have been trusted for decades:
- Standard Ignition (Standard Motor Products): A long-standing brand known for producing reliable, OE-style replacement parts. Their points are a go-to choice for standard tune-ups and dependable performance.
- Accel: Often viewed as a performance-oriented brand, Accel provides high-quality ignition components that are popular in the hot rod and classic car communities. They are a solid choice for a durable and reliable ignition contact set.
Pro Tip: Replace the Condenser at the Same Time
The condenser is a small capacitor that works with the points to prevent them from arcing and burning out prematurely. It is standard practice and highly recommended to replace the condenser whenever you replace the points. Most contact sets are sold as a kit that includes a new condenser.
Estimated Replacement Costs
Replacing the ignition contact set is one of the more affordable maintenance jobs for your classic Biscayne. The parts are inexpensive, and the labor is straightforward for a mechanic familiar with vintage cars.

Frequently Asked Questions (FAQ)
What exactly are "points"?
"Points" is the common name for the ignition contact set. They are a mechanical switch inside the distributor that opens and closes to trigger the ignition coil, creating the spark for the engine. This system was the standard before the widespread adoption of electronic ignition in the mid-1970s.
How often do I need to replace the ignition points?
Ignition points are a maintenance item. They should be checked and adjusted periodically, and replaced roughly every 10,000 to 15,000 miles, or whenever symptoms of wear appear. For a classic car that is not driven daily, this may translate to every few years.
Is replacing the ignition contact set a DIY job?
Yes, for those comfortable working on classic cars, this is a common DIY task. It requires removing the distributor cap to access the points. The key to a successful installation is setting the correct "gap" with a feeler gauge and, ideally, checking the "dwell" angle with a dwell meter to ensure proper timing.
Should I convert my Biscayne to electronic ignition?
This is a popular debate. A properly maintained points system is very reliable for a classic car. Electronic ignition conversions eliminate the need for adjusting points and can offer a more consistent spark. However, if an electronic module fails, it often does so without warning and cannot be easily fixed on the roadside, whereas worn points usually give you plenty of warning. Many owners prefer the originality and simple serviceability of the points system.
Technical Specifications
The most critical specification is the point gap, which must be set with a feeler gauge, or the dwell angle, which is set with a dwell meter. These settings are crucial for correct ignition timing.
