I think Demon, Edelbrock and Holley all make excellent carburetors.

And I quote the late Smokey Yunick from page 66 of POWER SECRETS
"The carburetor is really a pretty simple device. It doesn't know or care how big the engine is. It is strictly an air-fuel mixer that is calibrated to meter a specific amount of fuel according to the airflow. As more air passes the through the carburetor, it simply meters more fuel into the airstream. And I don't think there's any reason in the world to get tricky with a carburetor. If you are running a stock-block engine, it's probably going to fitted with a Holley carburetor. There are other good carburetors and almost any one of them can be made to produce as much peak power as the Holley."
