OK, fine use 0.  Now, if you think about my explainations, and even think a
bit further you'll see the logic in this.  If he can't find the gas to
support that then less will have to do, any action taken is/should be
considered temp. unless he's just going to Mickey Mouse it together, and
ignore doing a proper prom for it.
   I've tried 0-12d initial timing.  I've run from 0-10d hot spark bias, and
probably 0-24d cold.  I've run VE's from single digits to into the 20's at
idle.  I've tried numerous IAC pintles.
  I report what works for me.  I've got a 224d @ 050  110 LC 470" lift cam
and it idles at 650-675 in gear..

a
