I see you’re in Florida so corrosion in the distributor is a good possibility.
My Roush 427sr exhibited similar symptoms. I tried the heavier spring, lower idle speed, disconnected the choke and cleaned and adjusted the distributor. Didn’t fix it. Finally got rid of the problem by replacing the entire carb base plate. That did it.
And if you want to get rid of that bog, consider a nice 750cfm with mechanical secondaries. I swapped mine and it woke up the engine. Vacuum secondary carbs are not the best choice for our light cars. Even the Holley website will not recommend a vacuum secondary carb for a light car.
