Re: Utica Engine Number Prefixes

TSB 56T-20 gives the following, which doesn't agree completely with your info:

A & AA 5640
B & BB 5660-70
C 5688
D & DD 5680

Of the dozen or so 56 Caribbeans I've examined with their original engines and/or transmissions, all begin with the Utica "C" prefix. I've only examined a half-dozen or so Patricians and they've all begun with "D" prefix, thus in agreement with 56T-20.
