Does electronic ignition add horsepower?

One of the easiest ways to increase the horsepower output of your classic car is by converting from the old, maintenance-intensive, unreliable points/breaker-type ignition to electronic ignition. Points-type ignitions are subject to wear which degrades engine performance and this wear begins immediately.

How do you convert points to electronic ignition?

There are two ways you can go about converting from points to electronic ignition – you can install a factory electronic system that replaces the factory points and distributor, or you can install an aftermarket high-performance system with parts and components from various manufacturers.

How do you tell if you have points or electronic ignition?

If you do have a standard distributor cap, you can open the cap up and peek inside. A points type ignition will have what are called points (duh) installed in the distributor, just below the rotor (that colored plastic part that spins around when the engine is running).
