There’s little as frustrating as finishing up a build and not remembering the firing order so you can install the plug wires and fire it up.
Of course, most of us know the firing order for our own ride and others we’re familiar with, but that doesn’t help much when you’re a Ford guy and you’re helping a buddy finish up and fire-off his Cadillac.
This table shows Firing Order, Distributor Rotation Direction, and Cylinder Banks.

Technical Note: All American V8s have offset cylinder banks to accommodate side-by-side rod pairing on the crank throws. In the absence of published information, the number one cylinder will almost always be the one that is farthest forward regardless of which bank it is on.
The exception to this rule is the Pontiac V8 where the forward most cylinder is on the passenger side. The number one cylinder is still on the front left side, but it is not the most forward cylinder on the block.
