I'm running the original Carter 4bbl (650?) on the 440 in my New Yorker. When I put the new heads on I also used a felpro valley pan w/block offs. Would my best choke option be an electronic for the carter or picking up a new performer 750 with an electric choke? ($311 at mancini) Does someone sell an electronic choke I can bolt on the carter?
Also, after the car sits for a few days, or on cold mornings, if I don't catch it right away it won't start and I have to dump some gas down the carb. What's the best way to make it more reliable? My charger has an electric fuel pump and starts every time, regardless of how long it's been sitting, by turning the fuel on and waiting 20 seconds and pumping twice.

Electric choke add on for the carter would be a cheap fix or even a mechanical hand choke. I think you should be able to get a universal of either at the local parts store.
