[V8] Rear Diff ratio's?

[jpb3wvu at frontiernet.net]

Hi all,

I have been on the UrS car list after migrating to that model but
hope you can answer a question for me.  I had thought that on my
many years of lurking on this list that there were two different
rear end ratios for our V8's?  Do the PT motors have a different
rear end ratio (3.83?) than the 4.2 AB? (4.11) or are the rear
ends of the two the same?

I thought for certain that they were different.  It seems that
the UrS car guys really love the Torsen rear end in the V8 and
it is a common mod for an S car owner to swap out the electronic
locking rear diff for the V8's Torsen.

Thanks for any input.

John
