"I am having the engine of my 750D, engine # 1315-43101 totally rebuilt. To improve the drivability I am thinking about some changes:"
It seems like you have driven the car as it was in the photos? Is that correct?
If the previous owner (or you) installed the carbs your ace mechanic should give you a clear understanding why that investment has pitfalls if that alone was the change. He should also understand the 101 cam issues. Maybe he is only familiar with newer Alfas? My point is changing to twin Webers comes as only a starting point if you wish to improve "driveablity".. cams, timing, headers, oil pan, motor mounts, distributor will all have to be considered as part of the change to technically improve the drivability and changing only carbs has it's consequences.
Properly equipped and tuned, the stock engine should provide a pleasurable driving experience. If there are issues with smooth running, a Weber downdraft could be the only change necessary if you can trace the problem to fuel delivery,that would not lead to a chain-reaction of further changes and get better results . You might have issues with "altitude" in Suisse I am not aware of.
