I don't know what other carb shops do it but I can tell you what The Carb Shop in Ontario does. First they find out as much about your combination as possible. Once they build the carb they dyno it on an engine. The engine they use is a SBC that make just over 600hp. This gets the carb in the range it needs to be but it's not exact. They rebuilt my carb years ago and it was too lean for my engine. I had to up the jets sizes and tune the cam and discharge nozzles to get it right.
