The downdraft Weber was looking pretty attractive because of what I have
read about the need to maintain and occasionally rebuild the SU's, but the
power tuning book doesn't even mention the downdraft Weber, and only
mentions the sidedrafts in the context of racing.
Early twin SUs are far superior to the downdraft Weber some people fit due
to clearance issues with the brake booster. It is not a performance carb like
the side draft models but certainly seems to ride on their reputation -
people apparently like to be able to brag that they have a Weber on their
even when it is one of the downdrafts.
Put SUs on your car and forget about needing to rebuild them for the next
decade or so....
