What is the factory mechanical advance set for on an original 72 350 distributor?
72 cutlass 2-bbl 350 auto

I have a manual with distributor specs but they are all listed by distributor number (there are 6 different numbers) so I don't know which is the one you need.

Would you mind posting all 6?

You can check it on a bench with simple tools. PM me and later tonight I can explain how.

Unfortunately it is currently installed in my car. I just converted over to a 4 BBL and bumped my initial from 7 to around 14-15 degrees, which made a night and days difference for the better. Guesstimate as the balancer is stock with a stock timing tab.

Now trying to figure out total timing with mech adv kicked in, as I don't have an adjustable timing light.



Thanks

Clean up the balancer and put duct tape on it then let's say your tab goes from 0 to 10 you out your line at 0 and mark ten then put that line you just made on 0 and mark another line at 10. Then do it again now you have marked 40 degrees into your balancer split it in half and out small lines and that's 5 degrees.. poor mans timing tape
