Hmmwere pretty sure this thing needs to be rebuilt, judging from the amount of sand piled in the throttle bores. The good news is that the carb is complete and intact, and Sean matched the stamped codes to the original application (66 425ci Super Wildcat). We stole both the carb and intake from a self-service junkyard for $15. Thats an exceptionally awesome deal, but you should be able to score a good Q-jet core anywhere for no more than $10-$15. Nearly every GM four-barrel application from 65-81 used a Q-jet, so you should have little trouble finding a decent one.
