Truck Repair: 1964 chevy C-10, oil pressure switch, smallblock 350

Question
Hi van, I have a 64' C-10. I replaced the 283 with a 80's smallblock 350. The motor has a HEI dis. Headers, a pretty good custom exhaust, edelbrock manifold, a mild RV cam and a piece of junk Roch 4G carb. My question is, I need to replace the carb but I'm unsure of what type. Do I need electronic choke & if so what does the electronic part hook up to?(theres not much left in the way of electronics!!!)or do I need a manual choke? Is there such a thing as automatic (neither electric or manual) (thermocouple maybe?) Also i've been told that shes quite overcarbed. My goal is a little performance but reliability. Thanks for any help you could give me


Answer
The electronic part of the choke connects through an oil pressure switch to battery voltage.
it is only a heater element inside the choke spring housing, and is for the purpose of heating the choke spring so it will open.
That carb may or may not have a tube drawing heated air from port in the intake crossover, and may take forever to open without the electric heater.
