65 170 vacuum advance or not?

Yeah I'm not 100% sure what all adjustments he did except, he did unplug the hose going to the vacuum advance, adjusted the timing, and mixture. It ran better than it did when I took it to a supposed Mopar specialist shop who spent two days with it. In fact it ran better than it ever has since I've had it. I'd ultimately like to get so reliable enough that I can get in take off and run to the store and come back home without stalling or overheating. After he did all that this past summer we took it our and drove it around for a good hour in the 85 degree weather and it had no problems. Right now it's been too cold to fool with the car even in the garage so I just try to start it, shift through the gears, and let it run for awhile until I can get it out and drive it. Over the winter I've added the suggested carb insulator gasket Edelbrock told me to get, re-routed the fuel line the best I could to get it away from the heat, and I changed out the fuel pump. Mine was putting out 7psi which Edelbrock tech told me was too high for their carbs. When I changed the fuel pump it did go down to 5.5-6psi on the gauge. Maybe it will be better now.
