YES!.........The MSD ignition instructions specify a certain amount of GAP
setting increase or decrease depending on the way the engines been set up.
N/A engines typically need a slightly wider gap up to .050-.060,with
Multi-strike ignitions like the MSD OR Accell systems.
While the Supercharged or Nitrous engines may need a the gap closed
a few thousandths.......
I have the gap on my 3922's set a .038 instead of the factory spec of .040.
