4bbl Carb questions

Sounds like a reasonable plan to me. You will need to make arrangements for a kickdown linkage for the 2300. Don't know if the Super Six linkage will work with the 2300, it was designed around a Carter BBD. Both Lokar and Bouchillon Performance make a universal kickdown for the Mopar A/T. Lokar is sold through Summit and others, Bouchillon has it's own site.
