Do small, simple projects become extremely large and a little out of your league when it comes to your ride?
Has a simple distributor cap and rotor change quickly turned ugly? Has your once well-mannered carburetor suddenly become a smoke-puffing, gas spitting-monster?
Sometimes it’s helpful to have a cheat sheet in hand to help you navigate projects–big or small. For example, let’s say you’ve just installed a new cap and rotor kit on your carbureted V8, changed the spark plugs, and are ready to install a set of new wires.
But which wire goes where?
We’ve put together this V8 engine firing order and rotation (where applicable) cheat sheet for just such an occasion:
- AMC (most V8 engines): Clockwise 1-8-4-3-6-5-7-2
- Buick (most V8 except HEI): Clockwise 1-8-4-3-6-5-7-2
- Chevrolet: Clockwise 1-8-4-3-6-5-7-2
- GM LS: 1-8-7-2-6-5-4-3
- Small Chrysler: Clockwise 1-8-4-3-6-5-7-2
- Big Chrysler and Hemi: Counter-clockwise 1-8-4-3-6-5-7-2
- Most Ford V8: Counter-clockwise 1-5-4-2-6-3-7-8
- Ford (5.0L HO, 351W, 351M, 351C, 400): Counter-clockwise 1-3-7-2-6-5-4-8
- Most Ford modular (4.6/5.4L): 1-3-7-2-6-5-4-8
- Ford 5.0L Coyote: 1-5-4-8-6-3-7-2
- Oldsmobile (1967 and up): Counter-clockwise 1-8-4-3-6-5-7-2
- Pontiac (most 1955-81 V8 engines): Counter-clockwise 1-8-4-3-6-5-7-2 (Note: 307 Pontiac V8 engine rotates clockwise)
It’s important to remember that the numbering conventions for engine cylinders differs by manufacturer.
