As far as I know, the 1987 Chevrolet G10 Van did not come with a 250 Inline 6 cylinder, and I have never seen one in this year model van. The only 6 installed was the 4.3 liter V6. The firing order of the 4.3 is 1-6-5-4-3-2. There was a 292 Inline 6 cylinder installed in the fullsize pickup that year and the firing order for it and the 250 inline 6 cylinder are the same at 1-5-3-6-2-4.
The firing order for 1994 E 250 Ford van is 1, 4, 2, 5, 3, 6. The number one cylinder is at the front of the engine.
