Is firing order on 4.3ltr Chevy v6 clockwise?

The firing order on a 4.3L Chevy V6 is 1-6-5-4-3-2. This is not directly related to clockwise or counter-clockwise rotation. While the crankshaft rotates clockwise (looking from the front of the engine), the firing order describes the sequence of cylinders firing, which is determined by the camshaft and ignition system design, not simply the direction of crankshaft rotation.
