The Z06 appears most similar to the 5.3 MAF in its
freq/flow table. The 6.0 MAF info I have is a bit off
from the Z06 / 5.3, appears slightly leaner but still
well richer than the F-body MAF. I don't know if the
5.3/6.0 difference lies in the MAF itself or the intake
tract. The Z06 has no screen, the 5.3 does. Also
seems to be some difference between '01, and
later ('02-up) Z06 MAFs but I haven't found anything
definitive, only hints that '01 Z06 = 6.0 MAF P/N.
25318411 - New truck MAF (& LS6?) and '01 Z06
25168491 - original 85mm truck MAF, now obsolete
25341604 - Z06 MAF '02 85mm
If you find any error with these numbers or additional
85mm MAF P/Ns let me know, these are Web-scrounged.
25318411 and 25341604 will get you "live" parts hits.
gmpartsdirect has truck MAFs for $97 and Z06 MAFs for
about $105. Add a tweak-resistor and you can run either
of them on an F-body with little or no tuning needed.

If you do get the Z06 MAF, have a look at the
"Screwdriver SLP MAF" stuff here:
http://community.webshots.com/user/jimmyblue69
You will need to do this to get the right calibration
(unless somebody like SLP or maybe Pace (?) did it
for you). Not necessarily the little box, that's just
there 'cause I kept changing the value in the name
of science. Just the resistor.

One of the Pace units claims F-body calibration, I
have a picture of one that shows the same resistor
trick as SLP (whether they use the same value I
don't know, but should be close). But I think Pace
will also sell you a straight Z06 MAF w/ adapter
harness and if you had tuning capability this would
be represented well by a regular Z06 MAF table
where the SLP's fidelity across the range is to me
a bit suspect (being as they got to "close enough"
by a cheap trick, and how close is close enough?
They don't bother to make any claims).
