Unhappy Cold weather blues

I have a BB 454 in a 82 Chevy truck. When ever its starts getting cold out it stars running rough. I know GM's are natorious for being cold blooded, but this is a little more. After about 10 minute warm up and the choke is all the way open, i still have about a 2 MPG drop in the colder climate. I am running a Comp Cam, 224/224, with a Edelbrock performer set up and i opened the carb a little with the Performer RMP needle set. any suggestions on how i can keep this tuned right when the weather changes.
