TR7 BFH#56 -- Why are LBC carbs so complicated?

[Eganb@aol.com]

Probably a dumb question on my part, but why are SU and Zenith-Stromberg 
carburetors so complicated, compared to something like a Holley or Rochester 
carb?  

I'm always amazed at all the separate components that make up the carbs you 
find on LBCs, whereas a Holley four-barrel proabably has less than half the 
moving parts.  

Must be a reason for the different technology.

Anyone?
