Buyer’s Guide

With these great options for an HEI distributor for your 350 Chevy, you can easily pick one of these products and find everything you were looking for. However, before you make your decision, you may want to know a bit more information about HEI distributors in general.

So, we have compiled a list of some of the most common questions that consumers have asked about these products and found answers so that you can have the information that you need to make a final decision about which HEI distributor will be the right fit for you.

What does HEI stand for in an HEI distributor?

HEI stands for high energy ignition, or in other words, an electric ignition. When talking about an HEI distributor, we are referring to the GM 1974 to 1980 distributor cap design.

How do I know when my HEI distributor is going bad and needs to be replaced?

If the engine fails to start, then this means that the positive hot wire from the battery that feeds the distributor has no more voltage to it. The starter may still crank the engine, but there will be no sparks.

A plug wire engine miss, or any type of constant engine miss is a sign of a bad HEI distributor. This could be caused by having too much resistance, or a corroded connection.

A reduction in fuel economy will happen when the HEI distributor goes bad, and it will affect emissions and engine performance because this system controls the spark timing changes for the engine.

If you have to crank your engine repeatedly to get it to start, then this could be a sign of HEI distributor failure. This could be caused by a worn or carbon-corroded electrode that has increased in gap size or chipped.

If your vehicle fails a smog check, this could a sign that the HEI distributor is going bad because there is an insufficient spark or coil voltage. This would cause excessive hydrocarbons and carbon monoxide emissions, which will cause it to fail a smog check.

How to Diagnose HEI Distributer, No Spark No Start.:

Does an HEI distributor need vacuum advance?

If you want to add vacuum advance to your engine, then you can have better accelerating times and be able to speed away from red light and stop signs without a hitch.

Vacuum advance kits are fairly cheap, many are around 30-40 dollars a-piece, and can aid in your engine’s performance. So, if you have been thinking about adding vacuum advance to your engine, then know that you will not be disappointed.
