72 demon 340 needs a new carb! strong opinion or suggestion?

I never heard of a Thermoquad rated less than 850 CFM. No way would I replace one with a Holley given a choice.
So I wonder what the OP did for a carburetor? Did he rebuild his old one? Or did he buy that one offered by 4404spd, which was probably the best choice of all for his situation actually?
