The weber DGV,DFV,DGAV 32/36 carbs were used on several engines. Ford cortina's,BMW 2002's ,ect. These carbs really do work good if all things are right. To just bolt on an intake an carb without correcting the lift and duration,timing,or advance seldom works. Start at the begining, And remember,long intake runners work best with long duration at hiway speed.(remember the big chryslers with there crossram duel 4 barrels, big cruisers)I assume thats why the duel webers seem to work.Get rid of the progressive single. It's a good carb butI don't think it's best suited for the 914.

Just a thought
