D@mn SOB *$!#* What now?! Please HELP!

[84_GT350]

Well...I know one or two of the plugs had been fouled for quite a while, but even if one had been working I would've gotten something when I turned it over. And I doubt the others could have fouled so suddenly and simultaneously. Also, if it matters, for a month or two after the engine was warmed up when giving it throttle off idle it would rev, then drop and hesitate for a split second, then kick back in with no problem as rpms increased.
