I'd say an Edelbrock 600 with an electric choke would work great. Your car is a 4 speed, so I'm not sure if you'd need the Edelbrock throttle linkage adapter for Chrysler vehicles or not? I have that same carb on my 71 Challenger conv with a 360 and an LD340 intake, and it works awesome. All that being said...back in the day I had a 73 Challenger 340, and took the TQ off of it because I could never get it adjusted right. I put a Holley 650 spreadbore on it, and it ran like a gut shot cat! Good luck with it. :)
