Slant six intake/carb question.

Hi guys, I’m hoping to finally have my 66 valiant in my name soon ( dmv needs to see the vehicle running to START the process of getting a title in my name since one does not exist). I’ve rebuild the carb and it runs but not great. Can I stick a newer style carb ( not the twisty throttle kind) on the existing manifold? Or do I need to replace the manifold as well? I know I’ve got to replace the throttle and linkage and I’ll purchase those as soon as I know I can the car registered in my name. Thanks for the help guys. FYI it’s a 66 valiant, 170 slant six with a 3 speed manual.
