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.
