That's a Rochester Series 'B' carby and the kickdown cable attaches to the lower arm on the throttle linkage , you may have to go rob it off some old Nova / Chevelle Ect. in Pick-A-Part , for now it's not important as you can always manually pull the shift lever down one notch , that's a better way anyway .

Congrats on your new (to you) 250 C.I.D. ! now strip off all the accessories , mounts & ect. , plug the holes and scrub it Hospital clean & re spray it , then the accessories gloss black so when you re assemble it , it'll look really nice .
