Sounds link classic engine ping (i.e. minor detonation).  THis normally 
wouldn't be a major problem, but your engine has either the Ford EECIII or 
EECIV system, that has a knock sensor that kicks back the timing a few degrees 
if the engine starts pinging.  Something may be wrong with your electronic 
control unit.  My info comes from my '84 Ford shop manual, and is based on the 
assumption that the 84 was essentially an '83 carryover (my Mustang's 302 V8 
is, and so are most of the other V8's from what I've heard).  If you want 
a more specific answer, drop me a note and I'll tell you exactly what the 
shop manual says.
