Is a HEI distributor better?

Is a HEI distributor better?

The HEI delivers a more powerful ignition spark, and this allows the use of wider spark plug gaps to help ignite fuel quicker, and deliver a more complete combustion.

What years did Chevy use HEI distributor?

GM’s High energy ignition (HEI), designed and built by the Delco-Remy division of General Motors starting in 1974. These units were used on all engines in 1975 through the mid-1980s, with several different variations over the years.

What does a HEI distributor do?

HEI distributors are a popular swap on older GM cars originally equipped with points and condenser type ignition systems. The HEI system produces a more powerful spark, which allows for a wider spark plug gap for surer ignition of a fuel/air mix that may not be optimal.

What does HEI ignition stand for?

High energy ignition
High energy ignition, also known as H.E.I., is an electronic ignition system designed by the Delco-Remy Division of General Motors. It was used on all GM vehicles, at least in the North American market, from 1975 through the mid-1980s. Most—but not all—HEI systems have the ignition coil mounted in the distributor cap.

What is the outside diameter of the SBC HEI distributor wire?

Outside diameter approx. 6″ Value added SBC HEI Distributor and Spark Plug Wiring Kit With Over Valve Cover Wires. Kit # 916-02033 Value added SBC HEI Distributor and Spark Plug Wiring Kit With Under Header Wires. Kit # 916-02032

What is a HEI distributor and how does it work?

In the mid-’70s, leaner mixtures demanded greater voltage and more spark energy to kick off combustion. The HEI distributor is still an inductive-discharge ignition, but exchanges points for an electronic device called a module.

What is the difference between a Hei and point ignition?

The HEI distributor is still an inductive-discharge ignition, but exchanges points for an electronic device called a module. Since this system produces more voltage and amperage output than a point-type ignition, it requires a larger-diameter cap to prevent voltage crossfire inside the distributor cap.

What does Hei stand for?

Enter the High Energy Ignition (HEI) which effectively replaced the points-style systems that had been in service for decades. The GM HEI distributor was a wonder of the time. No longer was an external coil needed as the HEI incorporated one in the package. Also, no voltage resistor was needed to keep the points from burning.
