Pro Flo 4 Timing

I'm going to throw out what I found on my setup, and hopefully other people can confirm/deny what I've found. I don't want to drill/cut a hole in the cap to use a timing light, so I checked by eyeball and used the marks on my balancer. Zero was confirmed as TDC when I degreed my cam.

I started by marking the positions of the posts for cylinder 1 and 2 on the outside of the distributor body.

It looks like I might have mistimed the distributor when I stuck it. The Edelbrock addendum wants to see 12deg of advance "built in" by having the motor at 12° and then sticking the distributor in with the rotor at 0 and the hall effect right on the t short tooth.

When at TDC rotor was right at #1, so already not ideal. Every degree of advance moves it further back away from the post.

There's a 45 deg arc between any two posts on the cap (360/8=45). Rolling the motor to 15° btdc the rotor is approx 7.5° away from the #1 post. Rolling it to 35° btdc it's approx 15° away from the #1 post.

So, all in all, on my setup, it's not ideal, but it's unlikely that there would an accidental firing of cyl #2 instead of #1. I'm going to try advancing the rotor to place it as close to #1 when when running 25° of advance, or as much as the rotor adjustment will allow.

I'd like to see what others have on their setups, to confirm if they're seeing something similar.
Not sure if it’s been referenced previously but I found this video interesting and enlightening regarding the topic of vacuum advance & total timing!!
