I have a 78 Volare Premier with the Super Six that has a Carter BBD 8137S carb tag. Base is casting 2543 with main metering jet .086 and has metering rods 2228 .0665x.0635x.056. I have carb apart and cleaned but the venturi assembly is damaged on one side. Looks like it was tried to be removed and the brass jet is damaged on the one side. Here is the question? I have a BBD from a 318 that I got for parts and need to know if the cluster from it will work in my original. The Carter book says the my original has 220 CFM and the 318 I have is 285 CFM using 089 main jets but has 2 different rods. Can I get up to the 285 CFM on my original using the 089 mains and different rods along with the Venturi from the 318 parts carb. Thanks in advance Mike.
