" Still doesnt run as well as my carb'd engines"

My $0.02: Don't get EFI because the throttle
response/driveability/power/whatever is not satisfactory with a carb. A
well-tuned carb engine can do all those things as well as an EFI engine. And
EFI is more complex and more expensive. Now, there are arguments to getting
EFI of course. It normally lowers fuel consumption and pollution. And it
stays "in tune" longer than a carb. But it can also leave you stranded. Lots
of pros and cons. But don't get EFI because your carb (or ignition timing)
is out of tune. Fix it.

Of course there's one big advantage to EFI compared to a carb that appeal to
a lot of us I think. It's a new challenge. This is a community that likes to
try something new and different, right?

I still am the voice of reason in the EFI discussions.  I have been working
with my Retrotek EFI system for 4+ years now.  Still doesnt run as well as
my carb'd engines.  I am making progress, and I hope that one day I will
have a really nice setup.  But I would never do it on another vintage car.
And there is nothing plug and play about it.  I still have not achieved
satisfaction in cranking, cold engine running, and idle.  i have not yet
really worked on acceleration much at all.  With a chassis dyno and an EFI
system and some time, it is possible to really do some nice stuff.  But
without a chassis dyno, becomes more tedious.  And the various settings and
controls are not so intuitive and not so easy for an interested amateur.
MSD system looks more or less comparable to FAST EZ EFI and retrotek
(professional products).  The ACCEL DFI looks even more confusing to me...

P.S. - a big problem with the pantera is that, if the engine does not catch
on the first try with the starter, you have to turn ignition to off and then
on again to crank the starter again.  In some, maybe all, of these systems,
ignition off starts a process of resetting the idle control motor.  That
takes maybe a minute or so, but there is not outward indicator of the
process.  If you dont give it that full minute, then when you re-crank, the
idle motor is not in the right position and the car wont run right the
entire time it is running.  Ask me how many years that took me to figure
that out....  that is the kind of thing you discover when you try to make
these things work.  justin
