How do you check the firing order on a 350 Chevy?

How do you check the firing order on a 350 Chevy?

The most important thing to remember is that the firing order must follow the same pattern as the engine. The Chevy 350 firing order is 1-8-4-3-6-5-7-2. That means next to the number one spark plug wire will be the number 8 spark plug wire, the number 4 and so on in a clockwise rotation.

Will a car run with the wrong firing order?

When the firing order is wrong or delayed, the engine does not run properly. The spark may be delivered to the cylinder when there is no fuel/air mixture or before it is properly compressed. One symptom of an incorrect firing order is the engine does not run. Turning the ignition does not start the engine.

How do you tell if your distributor is 180 out?

Note the direction of engine rotation.

How long can you go without changing your timing belt?

Replacing your timing belt before it fails is something you do to reduce the risk of the severe engine damage I mentioned earlier. As a general rule of thumb, roughly 75,000 to 100,000 miles or 7–10 years (whichever comes first) is a reasonable replacement interval with minimal risk.
