What's the firing order on a 1939 oldsmobile flat

A 1996 Oldsmobile Regency Elite with a V6 engine typically has the firing order 1-6-5-4-3-2. The cylinders in a V6 engine are numbered progressively from the front of the engine in this conventional firing order, with cylinder 1 being the front-most cylinder on the driver's side. To find out the precise firing order for your particular engine model, always refer to the handbook or a trustworthy automotive reference.

The firing order is:

1-2-7-3-4-5-6-8

From the left (front) bank of cylinders are number 2-4-6-8 and the right (rear) bank cylinders are 1-3-5-7. Engine firing order is 1-2-7-3-4-5-6-8.

You might find the firing order is cast into the manifold a lot of the oldsmobiles had this!

call autozone find out the firing order.the coil is numbered.the firing is counted from left to right.(for ex. if your firing order is 316524) three would be on the left so you run that sparkplug wire to the number three on the coil,and so on.
