You can't get an AVS new. Rather than deal with another old-used-rebuilt
carb, I would suggest you go for a new Carter AFB or Edelbrock carb. The
Edelbrock is based on the AFB. You can get a 750 or 625 cfm. I don't know
which Imperials came with stock. I know that hp 440s came with 750 avs.
Either should bolt right on, but you may need the linkage kit. Check out
Summit or Jegs.
Good luck
Rob
