Reply to "Holley Strip Dominator angled carb base..."

Leveling the carburetor via machining of the mounting pad creates a bit more air cleaner clearance below the engine screen, most noticeable at the rear of the air cleaner. Leveling the carburetor with a wedge shaped spacer does not improve clearance. There is no performance advantage in leveling the carburetor ... as long as the float levels are adjusted properly in either situation. If the additional air cleaner clearance is desired, I would have the carburetor mounting pad machined, if not I would use the manifold as-is. I wouldn't use a wedge shaped spacer under any situation.

Tim Meyer, who has been posting here lately, is a good machinist, he's capable of performing the machine work to level the carburetor base if you want to go that route. And to answer another question, yes if I were having the carburetor mounting pad leveled, I would have the holes for the carb studs re-drilled as well ... by the same machinist leveling the carb mounting pad. There are a couple of different ways to approach that issue, I'd leave it up to the machinist to make that choice.

As John has indicated, I would expect some re-tuning of the carburetor to be necessary when swapping to the strip dominator manifold.
