This is a totally meaningless question and anyone that tries to answer it
will be offering information with zero value.
It is IMPOSSIBLE to compare two engines of different type, displacement, and
specification. BTW - you did know that unless you have a non-stock alloy
head, the MGB only uses ONE carb, not TWO, didn't you?
First, go buy a Weber book and find out what the settings for a BMW engine of
your state of tune might be (you don't bother offering cam information). That
is only a very basic guide to what size venturis and what other settings you
may want to try. Then have an expert do the tuning.
I take it that you are not such an expert from your question, as well as your
suggestion that a 45 DCOE must be too large for the 1600. It is not the carb
size so much as the venturi size that governs behaviour - I have one set of
40 DCOE with larger main venturis than another set of 45 DCOE I use on a
different engine.
Please believe me - if you have no specialised knowledge, Webers are NOT the
carbs to start trying to tune by guess, and by misinformation.
