A big vacuum leak will do it. :oops: I asked about the distributor because if you run an HEI make sure you get the low resistance center conductor for the cap. Make sure you have real good wires, MSD 8.5 or Accel 8.8 and keep your plug gap at or under .035. The Digital 7 lights a hefty fire. And no resistor plugs.
yeh i have a msd billet dist anbd im using moroso ultra 40 wires. the carb being loose seemed to be the fix. it crazy cuase the bolts were hand tight but to tighten didnt take but a turn and a half. i guess that just proves how much a air leak can cuase a lean condition
