I am running a similar setup in a 87 stang. Right now have an AOD but going to C4. My carb has no choke, vacumn secondaries, 80 jet in the secondary and 76 in the primary. In cool weather could probably go with 78 in the primary. I think the vac. with the quick change spring kit is the way to go on an automatic. I am running the spring for about 2600-2700 rpm secondary. Also, have the 50 pumper. If you have the fuel plate in the secondary get the kit to allow you to change the secondary jets. Watch out to be sure the bowl has a good seal as mine a small burr that had to be ground off as it was sucking air in the secondary.
Good Luck
