So my father has a 71 dart swinger with a 340. He was stating the he was needing to get a new carb. I would like to get this for him for christmas. What other information will I need to determine which carb would best suit his car? What I do know about the dart:

engine: 340(bore unknown)
trans: 727(3500 stall w/ line lock and trans brake)
current carb: holley 4777-4(and has 0323 right under that # on the carb)


Any suggestions? I think he was wanting to go with a bit smaller carb. Since we live in Colrodo, perhaps the altitude might be a consideration? Also, he used to race it quite a bit, but now is going more towards using it for cruising and leisure.

Any help would much appreciated.
