Choosing the Right Aftermarket Distributor for Your 1967-1971 Pontiac Firebird
Upgrade your classic Firebird's ignition from old points to a reliable new electronic system.
- Upgrading from the original points distributor to a new electronic system is the most significant reliability improvement for a 1967-1971 Firebird.
- Brands like Pertronix and MSD are highly recommended by owners for their performance and reliability over budget options.
- Proper installation and setting the ignition timing with a timing light are critical steps that should not be skipped.
- When upgrading to an electronic distributor, plan to also replace the spark plug wires and possibly the ignition coil to match the new system's requirements.
Signs of a Failing Distributor in Your Firebird
The original points-style distributors in 1967-1971 Firebirds require regular maintenance and are a common source of problems as they age. Worn internal parts, a bad cap, or failing points can leave you stranded. If you notice any of these symptoms, your distributor could be the culprit.
- Hard Starting or No Start: A bad distributor may not send power to the spark plugs, making the engine difficult to start or preventing it from starting at all.
- Rough Idle and Stalling: If the engine shakes at a stoplight or stalls, it can be a sign of a faulty distributor cap or incorrect timing.
- Engine Misfires and Hesitation: You might feel a jerking or stumbling when you accelerate. This can happen when the spark isn't delivered at the right time.
- Backfiring: A loud pop from the exhaust can be caused by unburned fuel igniting, a problem often linked to a bad distributor cap or incorrect timing.
Points vs. Electronic Ignition: A Necessary Upgrade
The original distributors in these Firebirds used breaker points, which are mechanical contacts that open and close to fire the coil. Points wear down, burn, and require regular adjustment. Nearly all new aftermarket distributors are electronic (often called HEI, or High Energy Ignition). These use magnetic pickups or optical sensors instead of points, providing a more consistent, powerful spark and requiring virtually no maintenance. For a classic Firebird that gets driven, upgrading from points to an electronic distributor is one of the best reliability improvements you can make.
Choosing the Right Aftermarket Distributor
When shopping for a new distributor, you're choosing between different types of electronic systems. The brands available offer different tiers of performance and quality.
Performance Brands (MSD, FAST)
Brands like MSD and FAST are top-tier choices for performance applications. They offer high-quality billet aluminum distributors designed for high-RPM stability and powerful spark output. An MSD 'Ready-to-Run' distributor is a popular option that includes a built-in ignition module, simplifying installation. While they are the most expensive option, they are the go-to for modified engines or those seeking maximum performance and reliability.
Reliable Upgrades (Pertronix)
Pertronix is extremely popular among classic car owners. They offer both complete electronic distributors (Flame-Thrower series) and simple conversion kits (Ignitor series) that fit inside your stock distributor cap to maintain an original look. Forum discussions show that many Firebird owners have had success with Pertronix for street-driven cars, noting easier starts and smoother running. While some users report occasional module failures, they remain a very common and well-regarded upgrade from points.
Standard Replacement Brands (Cardone, WAI Global)
Cardone and WAI Global offer new electronic distributors that are typically more budget-friendly. These are designed to be direct OE-style replacements. WAI Global markets its parts as 100% new and built to meet or exceed OE specifications. Cardone also offers new units, not just remanufactured ones. However, owner reviews for these brands can be mixed. Some users report success, while others have experienced premature failures or quality control issues. These can be a viable option for a stock vehicle on a tight budget, but performance and long-term durability may not match the higher-tier brands.
Frequently Asked Questions
Do I need to upgrade to an electronic distributor?
While you can keep the original points system, upgrading to an electronic distributor is highly recommended for any 1967-1971 Firebird that is driven regularly. It eliminates the need for frequent maintenance and provides a more reliable and powerful spark, leading to easier starting and smoother engine operation.
Can I install a new distributor myself?
Yes, this is a common DIY job for those with some mechanical experience. The process involves removing the old distributor, setting the engine to Top Dead Center (TDC) on cylinder #1, installing the new unit, and then setting the ignition timing with a timing light. It is critical to mark the position of the old rotor and distributor housing before removal to make installation easier. Getting the timing right is the most crucial step for engine performance and safety.
Do I need a new ignition coil with my new distributor?
It depends on the distributor. Many HEI-style distributors have the coil built into the cap. Others, like MSD's 'Ready-to-Run' models, have a built-in module but still require a separate, powerful external coil. Always check the manufacturer's recommendations. A stock coil designed for a points system is generally not sufficient for a new electronic setup.
What is 'setting the timing' and why is it important?
Ignition timing refers to the exact moment the spark plug fires in relation to the piston's position. Setting the timing involves rotating the distributor housing slightly while the engine is running and using a timing light to align marks on the crankshaft pulley with a pointer on the engine. Correct timing is absolutely critical for engine performance, fuel economy, and preventing engine damage.
