I assume you have a 302 in that Mustang.  When Ford EFI'ed the 302, they
first used two injectors in a TBI configuration.  Later they went to 8
port injectors.

I'm not sure exactly what you are asking.  In a TBI setup, the injector
firing is synchronized with the intake pulses - if that's what you were
asking.  If you were asking about cylinder to cylinder variation, the
OEMs have and still do get by with injecting the "same" amount for all cylinders.
