I bought a used holley 500 CFM 2 bbl to put on a 302 in my 65 galaxie,the carb is probably too big and when I put it on it dumped way too much fuel and was not a stuck float so I put the motorcraft carb back on and took the holley apart. The holley carb has 73 jets and the original motorcraft 2 bbl has 48 jets,does the holley require that big of jets or should I put in the size of the original carb to start the dialing in process.
