nah, i do have the vacuum MSD, but i've been pretty good about disconnecting it when trying to time it (though i've forgotten a few times).

food for thought: I just set the tune on my 66. it has TW heads, rpm air gap intake, and .530 230 dur cam. Mine liked a lot of timing. 38 degrees at 3600 rpm with vac advance off. I connected my vac advance to manifold vacuum and it has 42 degrees at idle. I took an engines class and found out why the motor prefers that kind of timing at idle, and I decided it was okay and safe for me to run that much. it smoothed my idle out a bunch. with vac adv disconnected, my initial timing was 20 deg
So.....it's running like it should?
Well, the important thing is that it's fixed. I'm not going to give you too much grief here........
Take good notes on the trans swap as well!! That is a project I should be doing twice this summer myself, as soon as i get back.......
better set your total timing to less than 40.
