>I've see the two on the floor next to each other, and they definitely
have different patterns.  One was a 700r4 from a '86 S-10 Blazer (2.8
V6) , the other was a 700r4 from a '91 Caprice (5.7 V8).  No way would
one bolt to the engine of the other.  I don't have pictures, but there
is on on page 4-3 of the S-10 V8 swap manual from JTR.<

I stand corrected.  Since the 2.8L was also used in the F-bodies, GM must
have made a second case casting for a few years.  I assume the F-body
700-R4 shared the same unusual bolt pattern.
