You'll need another distributor.
No, the CCC Q-jets don't suck, they are essentialy the same as any other Q-jet, except primary fuel metering is handled by a solenoid, and they have a TPS. The setup is as close to TBI as you can get without injectors. Has an O2 sensor and all. The CCC carbs suffer from the same problems any other Q-jet does, mainly wear and junk in the float bowl, carbon buildup, and the only real other problem that is exclusive to the CCC carb, the TPS.
If something is wrong in the system (like bad MAP sensor, etc) then of course it won't run right, and changing the cam or engine can cause problems, but that is no different than the fuel injection systems.
