Need firing order & dwell on a 1972 455 engine

[Fred Rawling]

I mixed up the wires while changine the distributor cap.

Can anyone give me the firing order and dwell?

Isn't the firing order cast into your intake manifold? They usually are. See if it says this:

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

My Pontiac's all used a Delco D-106-PS points. I always used a matchbook cover to adjust them to .016".

Hope this helps, Fred.

Thanks, I will check it right now.

My 73 caprice with a 400 had the dwell at 33 degrees. I was going to set the Buick at that until I could find the correct dwell tomorrow.

If anyone does know the setting, I would rather finish it tonight.

I found the firing order on the manifold. The distributor rotates clockwise on the Buick. Now I have to figure out which terminal on the distributor cap is #1.

If it is still set up like it came from the factory, nimber 1 is the first one clockwise from the tin door

Thanks for the help. I got it together and running.

It is factory with 50,000 miles on it. 2000 of them I put on it since I bought it.

I thought I answered this already in another thread.

Dwell is 30*

EDIT: I did:
