305 Chevy Firing Order:
The firing order for a 305 Chevy engine (and most small block Chevys) is:
* 1-8-4-3-6-5-7-2
How to Find #1 Cylinder:
1. Distribute Cap: Look at your distributor cap. The number "1" on the cap usually indicates the location of the #1 spark plug wire.
2. Harmonic Balancer: The #1 cylinder is usually marked on the harmonic balancer (the pulley at the front of the crankshaft).
3. Engine Block: Some engine blocks have a casting mark or a "1" cast directly on the block near the #1 cylinder head.
Important Note: It's crucial to double-check these markings to ensure you've correctly identified the #1 cylinder. There's no single "universal" way to mark them, and some engines may have different markings than others.
Why is Firing Order Important?
The firing order is crucial for smooth engine operation. It ensures that the cylinders fire in a specific sequence, creating balanced and consistent power output.
