What is the firing order for a 1987 Chevy G 10 van with a straight six 250?
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.
