| RE: dual quad - which carbs? |

It's difficult for someone without vast carburetor experience to make carbs intended for single quad applications function correctly on mulit-carb setups, Joe. The "average Joe" won't have a lot of luck because the idle and main circuits are different since instead of one carb's circuit contributing to the proper idle and cruise you have two carbs doing it and you'd have to reason that each carb should contribute half to the equation. There lies the problem. The idle and highspeed air bleeds and metering circuits are different in multi-carb setups so that both carbs meter the same air and fuel flow.
As you've already noted, both Holley and Edelbrock offer different carbs for multi-carb setups for this very reason.
It's possible for someone to have a dual quad work okay with single quad carbs but the difference between these "functional" setups and one using correct dual quads is like night and day. |
