J-bodies and MAP vs MAF

[lkurek at smtpgate.anl.gov]

     Whoa...time out on this.
     
     Like I said, I had an 89 Z24, and it didn't have VATS and it was a MAP 
     only system. However, I just swapped an 89 Camaro 2.8 into my S10, and 
     not only did it NOT have DIS or VATS, it also has a MAF sensor. Funny 
     thing is, the MAF isn't a hotwire type...it has what looks like a 
     thermistor or something in the airstream, and the circuit board is 
     internally mounted, also in the airstream.
     
     FYI, it kind of ticked me off to find the Camaro motor still had HEI 
     and a MAF. After the Z24, I came to realize the joys of DIS!!!
     
     TTYL!

  Hi,
 I've been told different things by different people about whether J-body V6s
are MAF or MAP.  According to the schematics I've seen, some are MAF and some 
are MAP based on different years and\or models.  The manuals I have only go up 
to '90, however.
 Does anyone know if any J-bodies are MAP based, and what years or models?  I
don't know if I should trust the Chilton manuals I've been lookin at or not.
 Also, If all I can find is a MAF based system with a 7730 ECM, is this
difficult to convert to MAP?  I realize I'd have to get a prom for a MAP based 
care (F-body V6).  What about the wiring to the MAP?  Is there "vestual" 
wiring in the harness?
