A followup question or two related to your comments.  The V8 quattro is a
model I haven't worked on.   My wife drives a 91 100 front wheeler and my
old workhorse is a 1989 200 turbo quattro avant........so some of the
technical stuff on the V8 is new to me.

You mention the ABH engine as being a possibility for a swap.  What is there
different (besides the obvious engine displacement) that make the ABH a
candidate for a swap while the PT seems to be a lost soul!   For whatever
reason are more parts available for the ABH and also  the shop manual that
covers the ABH engine, does it cover rebuilding info with the short block,
unlike the PT?   I guess my question, did Audi consider the ABH short block
to also be unrebuildable?
Is there an advantage of using the later 4.2  ABZ engine rather than the
ABH..........other than a better chance of having fewer miles, and I assume
more hp?

Also thanks to Scott for the info on the shop manual regarding lack of
information on the PT short block
