Fabion,
I think it would be a good idea at this point to summarize where you're at. In order for someone here to help. they need to know where you started with this car when problems began and what you've done, changed, replaced.
For example,
I can tell from looking at your past threads that it looks like you started with a weber two barrel and 'load-o-matic' distributor (although don't know if this was confirmed...doesn't matter cause you replaced it) ported off manifold vacum by the looks of this pic and the following post:

Then at some point you believed you had the 'new' distributor 180* out, and corrected that...then everything was fine according to the following post 'everything good':
http://fordsix.com/forum/viewtopic.php? ... ht=#425023
Then you started this post that says everything was 'fine' until you broke down in the middle of the road.
I'm not trying to be critical of you, and I understand the frustration (that is a very nice looking ride), but think it's time to draw back a little and get big picture in order to figure out where your problems started and why, cause without the benefit of searching all your posts/threads (takes time and detective work) it's hard to figure out where to go from here, and most suggestions are going to be relative only to what info you have included here. I hesitate to say it might even be worthwhile to start yet another thread giving as much history, background, details and pictures of how you got to where you are now.
Not to keep :deadhorse: , but you mention in one of the other threads that you changed the points, but you don't seem familiar with gapping/dwell settings (maybe you got lucky?), cause that was prior to this thread that starts off with all was fine 'until'....I assume you got acceloration above 30mph that you stated. when you first joined us, you weren't able to do before...again 'all was fine until'??? Point is this thread in itself has listed just about everything that could be a problem, and I'm sure you're mostly concerned about what particular one or more is the problem. I just don't see a path or opportunity for anyone to help you out of this situation without some pull back and reassment (we've got a tiger by the tail approach)...maybe just from what I've compiled you/we/us can...but at the moment I need a break cause just compiling this felt like giving birth
Conclusion...think about the new thread but start it off right, and hang in there.
