If you were in the local Cobra club we would slap on an extra MSD 6AL if our first slapping of the Holley 750 Vac Secondary didn't cure the problem. Remember, there are two clues to your problem: 1) Your car originally ran great, but now is running like crap; and 2) An abundance of heat accompanied that change in performance.

Now, you could have more than one thing wrong with your car, but probably not. But maybe. Not everything that could go bad on your engine is going to cause both symptoms. But if you think really generally, the problem is likely to be 1) Too much air in your fuel air mixture; or 2) The spark is firing at the wrong time. Possible problem #1 could have the air coming in through the carb, or from somewhere else; and problem #2 could have a couple of different causes. Now, it could also be a bizarre combination of something else, but those are two most likely scenarios.

Remember everyone on here is a diagnostic genius, so we'll eventually stumble on the solution.
