Carbs

[Anonymous]

What is the best carby to run on a mild 250 crossflow. I am thinking of a 390 cfm 4 barrel holley with vac secondaries to make about 200 hp at the flywheel. I have little knowledge of other types. Also, would a 350 cfm 4 barrel be better than a 350 cfm 2 barrel, what is the reasoning for going to 4 barrel. Also, what is the go with carby spacers, do they really make a difference or are they just another mock bolt on part that does virtually nothing?

Thanks everyone
