We have a '72 SS 402 with a factory Q-Jet. In switching to the Edelbrock Air-Gap mainifold there is no provision for the mechanical choke. Which is the correct electric choke for this carb? (Napa P/N or other?)

I don't think you can add an electric choke to a Q-jet which did not originally come with one. My guess is you will need to replace the carb if you want an electric choke, Edelbrock makes one and some late model Q-jets did too.
