By | July 25, 2022



Are you struggling to figure out how to wire the Chevy 350 HEI distributor correctly? Don't worry, it's not as complicated as it may seem. In this article, we'll explain the firing order and wiring diagram of the Chevy 350 HEI distributor so you can quickly and easily get your engine up and running.

When it comes to firing order, every engine has its own unique sequence that must be followed for it to run properly. The Chevy 350 HEI distributor has a firing order of 1-8-4-3-6-5-7-2. This firing order allows the spark plugs to ignite in the correct order and ensure that each cylinder receives the combustion it needs for the engine to run.

Now that you know the firing order, it's time to tackle the wiring diagram. Thanks to HEI (High Energy Ignition) technology, wiring the Chevy 350 HEI distributor is relatively straightforward. First, you'll need to connect the battery positive wire to the "BAT" terminal on the distributor. Next, you'll want to attach the ignition coil wire to the "+" terminal on the distributor. Finally, you'll need to connect the spark plug wires according to the firing order given earlier.

It's important to note that the Chevy 350 HEI distributor requires two separate power sources in order to function correctly. The first power source is the ignition module, which should be connected via the external 12v terminal on the distributor. The second power source is the "TACH" terminal, which should be connected to the tachometer in order to monitor the engine rpm.

Once everything is connected, you're ready to start your engine. The Chevy 350 HEI distributor will ensure a perfectly timed spark for each cylinder in the firing order that's been designed specifically for your engine. With this easy-to-follow wiring diagram and fire order information, you can be sure that your engine will run like a dream.
