We need to know size engine you have.
I don't know what size your engine is but here are some (2.0L) engine Firing order: 1-3-4-2 Distributor rotation: clockwise (2.5L) engine Firing order: 1-3-4-2 Distributor rotation: clockwise (2.8L) engine Firing order: 1-2-3-4-5-6 Distributor rotation: clockwise (4.3L) engine Firing order: 1-6-5-4-3-2 Distributor rotation: clockwise
Firing order 1-6-5-4-3-2
firing order 153624.......rotation is clockwise
Engine rotation is determined by sitting in the driver's seat. But engine rotation is of no consequence when determine firing order. It is the rotation of the rotor in the distributor that is important. That is easily found by removing the distributor cap and bumping the engine over and looking at the rotor. Does it rotate clockwise or counter clockwise?
the firing order is the same as Chevy 350 except opposite rotation instead of clockwise it is counter clockwise
