The firing order should be 1-8-4-3-6-5-7-2.
1,8,4,3,6,5,7,2.
18436572
18436572
its stamped on top of the intake manifold
V-8 or straight 6?
No, after 1987 the Caprice switched from the 5x 4.75" to the 5x5"
the firing order for a Pontiac 400 v8 from 1967-77 is 1-8-4-3-6-5-7-2
Not likely as GM restyled the Caprice/Impala slightly in 1980.
77-85 Impala, 77-90 Caprice, 78-83 Malibu, 78-88 Monte Carlo/El Camino
1-5-3-6-2-4 Distributor rotates clockwise.
