When setting the dwell, do you also disconnect the vacuum advance? I know I do this for timing, even have a machine bolt that I keep in my bureau for it (to make sure it doesn't get into the OTHER mix). But I'm not sure whether to do it for dwell. Also, the chilton's says 28-30 degrees, but a local been around the block since the 50s mechanic says he puts them at 32. I have a 70 Chevelle with a 307 and 4bbl setup, running between 12-14 timing and have rapidfire plugs.
Thanks in advance!
