[ba] Audi V8 3.6 -> 4.2

[Buchholz, Steven]

... you look like you should join the V8 list!  What are you looking to do
... put a V8 in your 4000?  ;-)  Unfortunately the ABH is a bit more than a
bored out PT ... different cylinder spacing and such but other than that
they are somewhat compatible.  Living here in California you need to put
some thought to what the smog pros are going to say about it too.  Are you
thinking about dropping a 4.2 in place of an automatic in a 3.6?  If so, I
think I'd recommend that you swap the transmission as well ... and perhaps
even the rear diff ... Audi put a more stout dear diff in the newer V8s.
Once again, if you're talking about a car with an automatic, you might
seriously think about just going out and getting a '92-on V8.  If you happen
to have a 5-speed it would be a different story ... the 5-speeds have the
same rear diff as the 4.2 automatics ... and as a matter of fact I'm trying
to put a plan together for dropping a 4.2 into one of my '91 5-speeds ...
