I have way to many passes on both qjets and Holly junk before I got a real race car(no doors, you know injection is neat but I'd rather be blown :-laf ) The whole purpose of a carb is to be able to change to existing conditions, something a double pumper did not do and the vacuum secondary barley did. You cannot even compare a closed loop injected system to any carb'd application and even the old Holly throttle body changed for air density and demand better than any regular Holly's. Holly made a lot of after market tuners rich with there poor designs. If I had known you can make HP this easy I would have had a diesel dragster 20 yrs ago.
