Ignition Contact Set Guide for the 1966-1975 Chevrolet Caprice
Keep your classic Caprice's ignition firing reliably with the right set of points.
- The ignition contact set (points) is a standard maintenance item that should be replaced every 10-12,000 miles.
- Symptoms of failure include rough running, hard starting, stalling, and reduced power.
- Always replace the condenser at the same time as the points; they are usually sold as a kit.
- Standard Ignition is a reliable stock replacement, while Accel offers a good performance upgrade.
Is Your Caprice's Ignition Contact Set Failing?
Ignition points are a wear item, meaning they require regular replacement. The rubbing block wears down, and the electrical contacts can burn or pit over time. When they start to fail, your engine's performance will suffer. Watch for these common symptoms:
- Hard Starting or No-Start: The engine cranks but struggles to fire up, or won't start at all. This can happen when the points are too worn or misaligned to create a proper electrical signal.
- Rough Running and Misfires: Worn or dirty points can cause an inconsistent spark, leading to a rough idle, sputtering, and engine hesitation during acceleration.
- Engine Stalling: The engine may stall unexpectedly, especially when coming to a stop or at idle. This can be a critical issue if it happens while driving.
- Reduced Power: Your Caprice may feel sluggish and lack its usual acceleration because the weak or poorly timed spark is not burning fuel efficiently.
- Backfiring: Incorrect spark timing from failing points can cause unburned fuel to ignite in the exhaust system, resulting in loud popping sounds.
Choosing the Right Aftermarket Ignition Contact Set
For a classic vehicle like the 1966-1975 Caprice, new original equipment (OEM) parts from GM are generally not available. The aftermarket is the primary source for ignition points, and quality is key. Fortunately, several reputable brands produce reliable sets for your vehicle.
In most cases, buying a kit that includes both the ignition points and a new condenser is the best practice. Replacing both at the same time ensures all components are fresh and prevents the old condenser from causing premature failure of the new points.
Brand Quality Tiers
Standard Replacement (Good): Standard Ignition (Standard Motor Products)
Standard Motor Products (SMP) is a long-standing manufacturer that produces a huge range of ignition components. They are known for making parts that meet original specifications and are a reliable choice for a stock or daily-driven Caprice. In fact, SMP manufactures parts for many other brands, so you are often getting a quality component regardless of the box it comes in.
Performance Upgrade (Better): Accel
Accel is a well-known performance brand. Their ignition point sets are often built with higher-tension springs designed to prevent "points float" at high engine RPMs. If you have a modified engine or simply want a more robust component, Accel is considered a great option by many classic car enthusiasts. While they may cost more, they are proven in performance applications.
Aftermarket Ignition Contact Set Cost
| Brand Tier | Typical Price Range (Part Only) |
|---|---|
| Standard Replacement (e.g., Standard Ignition) | $21.11 - $30.00 |
| Performance (e.g., Accel) | $30.00 - $37.15+ |
Known Issues & Recalls
Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or technical service bulletins (TSBs) specifically for the ignition contact set on the 1966-1975 Chevrolet Caprice. Major GM ignition recalls in recent years were for the ignition *switch* on much newer vehicles and do not apply to this part.
Frequently Asked Questions (FAQ)
How often do I need to replace ignition points?
Ignition points are a maintenance item. For a daily driver, they should be inspected and likely replaced as part of a tune-up every 10,000 to 12,000 miles. The rubbing block wears down, and the gap changes, which affects engine timing and performance.
Should I replace the condenser with the points?
Yes, it is highly recommended to replace the condenser every time you replace the points. A failing condenser can cause the new points to burn out very quickly. They are typically sold together in a convenient kit.
What tools are needed to replace ignition points?
You will need basic hand tools like screwdrivers and a wrench to turn the engine over. To set the points correctly, you will also need a feeler gauge to set the initial gap and ideally a dwell meter to fine-tune the adjustment with the engine running.
What is the difference between points and electronic ignition?
Points are a mechanical system that wears out and needs regular adjustment. Electronic ignition conversion kits (like those from Pertronix or FAST) replace the points and condenser with a magnetic or optical sensor. This provides a more reliable spark, requires virtually no maintenance, and is a very popular upgrade for classic cars like the Caprice.
Technical Specifications
This is a mechanical contact breaker point set for a GM V8 distributor. It includes the contact set and condenser. Proper adjustment requires setting the point gap with a feeler gauge (e.g., 0.019 inches for some V8s) and verifying the dwell angle with a dwell meter (e.g., 30 degrees for V8s).
