Hello All -

I have an HEI ignition and up until a couple
of days ago it ran fine, now I noticed that it
has a miss.

Well, along with the miss is a "snapping" sound.
Anyone know about HEI? Everytime is misses,
is snaps, not a loud snap, but similar to electrical
surges.................Is there something I
should be checking, what could be causing the
snapping and missing?
Could it be timing, a bad plug, the HEI system
failing....should I go back to the standard setup?

Thanks,
James
