simplyconnected Member Registered: 11/06/07 Posts: 533 Loc: Detroit (Royal Oak), Michigan	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.

Fred Rawling Member Registered: 03/11/00 Posts: 761 Loc: Bellflower, Ca., Los Angeles C...	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. Fred
