[T3] 1971 Squareback F.I. Auto; new engine coming

[Stet Sanborn]

Hey Everyone -

First off, thanks for years of great advice; I've been lurking for a long
time and many of your emails have answered questions I didn't even knew I
had.

I'm starting the planning process for an engine replacement on my 1971
Squareback.  I'm planning to retain by fuel injection, as its been trouble
free for me for the last 9 years, and I used to work for Bosch, so I have a
sentimental attachment to it.  I'm likely going to purchase a longblock
from ACN, mostly to save time off from work.  Here are my questions, before
I dive too deep:

1) I've got the factory 3-speed auto.  The car has just over 100,000 miles
on it; if I'm doing an engine swap, should I also find a shop to do an
overhaul on the transmission?  I haven't noticed any problems (other than I
need to adjust my kickdown switch).  But; given age, etc... is it best done
now while I've got the engine already coming out? They seem to be a pretty
robust build.

2) I'm trying to decide between a stock 1600, or ACN's 1800cc
mini-stroker.  Any trouble with a larger displacement and the Automatic
transmission?  A few folks on Samba have indicated they've done the 1800cc
with stock F.I; but I wanted to run in by the experts.  I wouldn't mind a
bit of extra power, but not at the expense of other parts of the car.

3) The car also has the dealer installed A/C unit, although I'm pretty sure
the compressor was leaking, so I disconnected it years ago and plugged the
holes into the fan housing.  Have their been any new products out there for
replacement compressors (more efficient, less drag, etc) that anyone has
seen?  I'm tempted just to pull it out completely, but might give it
another shot at life.

Cheers,
Stet
