I have a 1968 Galaxie 500 with a 390 that has a 2bbl intake and carb. I'm about to buy a 4bbl intake for it to help it breathe better. I have been looking into a Demon carb that is equipped with electric choke. My 2bbl that is on there (a Tomco remanufactured from my employer Oreilly's) is equipped with manual choke. What all do I need to do to accommodate that electric choke carb?
