I guess a good question would be what percentage of your customers or people that you know that have a holley shouldn't have one LOL..
I've got several customers that had to have a Holley... (Daily driver Cruise night cars).. and when I asked them if they knew how to adjust it... All I got was the deer in the headlights stare... Not that I would have not got the same look if it would have been an Edelbrock but it would have been much easier to teach them... Without sight Windows I'm not a big fan of spilling fuel on the motor while running to get the floats adjusted correctly...
Again I agree with the racing world but the problem is the hot rod world is just doing monkey see monkey do and should probably not be messing with Holley carburetors..
I would go out on a limb and say 95% of the 50000 plus members of this forum are hot rods daily driver people and they would probably benefit from an Edelbrock and being able to simply adjust it.. personally I found it easier to get someone to understand at the very least how an Edelbrock carburetor works as opposed to a holley.. also I like to mention the non leak design for people that don't like to fiddle with their carburetor every now and again and replace seals..
