Myron is correct on the Carter's. Regarding the triple Webers, I feel they are a bit extreme for the street. I had a complete Clifford/Weber 40DCOE setup for my GMC, and ending up selling it after doing some measuring and trial fits. If you want to run air cleaners on these things you will have interference problems with the fender bracing, and inner fenders, and probably the firewall too. Also, my power steering pump was smack where the front carb would go. Add that to the setup and tuning effort, it was more than I wanted to undertake. I do have some history with Webers, and they are absolutely terrific performance carbs, but parts are expensive and you need a handful of them to do the trial & error routine to get them to run well. That said, nothing beats Webers on an inline six for the open-hood jaw-dropping factor!
