hey read you heat issue , the hot running side , which side is it ? if its the pass side and you have stock exhaust manifolds on it . well it could be the damper flap part way closed . they stick all the time and sometime the return spring breaks as well . and black exhaust restarts could be leak down of the carb do to the heat crossover in the intake cooking the fuel out of the carb , heat gasses fuel rises to the top hit the airclear lid and drops down into the intake manifold and yes floods it with heated fuel which sits there until you crank it or drains down into the cylinders and by the rings then poluts the oil with fuel , bad for everything that is . here in calif we got crap fuel , it is a big issue , we in'd up blocking that crossover , but calif is alot warmer then your state . so for cold weather cars . we found that ford ( sorry for cussing ) used a water block under the carb works good enough for the colder starts . just has the heater hose routed thru it . if your running a small based two bbl you will be doing some big mods to it or even making your own . all of them i've seen are holley based bolt pattern , and a two bbl holley is larger then a carter or a stronberg ,or any other carbs used by chrysler . i'll just say a la with just one two bbl , not the six pack set up . hope i have helped . pm
