Are the Autolite 764s too cold for winter?

[Drew1287]

Since I added the charger I switched to the 2 heat range colder autolite 764s. I did this to prevent any detonation, of which I have no problems with. The Car does however idle VERY rough and has no power from about idle to 1000rpms. I think they are too cold for the winter time? Should I step up to the 765s or 766s?

Also, I am running my vortech kit with the 3.6 pully with stock injectors, I do however have the 190lph intank pump and trex, whats the smallest pully I could run safely on this setup with my current 12:1 FMU?

I live in MA, it's 20 degree F right now, been colder the last few days though (snowing tonight). I'mm running Autolite 764's without a problem. Everyone recommends them.
