I've yet to find any 'body casting' differences in the 40's.
the suffix number is the designation given to the jetting,
used as configured for a particular OEM setup.
...just like the various AUDxxx numbers of SU carbs.
yes, yes, yes, I know I know....SU's did have differences
other
than jets, etc but sake of conversation, the inference is
the same.
