After 5 years of carbs on a 3.0 I can say the list is 100% accurate.
Honestly, they are a love/dislike thing. (Hate is too strong a word here).
There is no doubt there is added power especially with a cam change. They look awesome and have a vintage look that make you smile and garners a lot of positive atention.
But the intake noise can be irritating of if the carbs are out of adjustment. I measured over 95db inside the car honking around. Full throttle is closer to 100db.
Fuel mileage is definately worse. But highway cruising can be ok. 20 mpg at 65+. Around town is where you suffer because you have to run them rich to handle throttle motion.
Throttle response? I guess they are better than CIS. But it only matters if you are stomping on it. An only if your acceleration jet can keep up with the throttle. Otherwise I'm not sure the difference is really great.
I will be going back to CIS in the future unless I go efi.
Changing to carbs is really expensive when you add in all of the changes that are needed. Plus alternate jets. While not as expensive as efi. I'm not sure if I haven't already spent the equivalent of a efi system with the tweaks, rebuild, manifold upgrade and recently a cam.
So should you do it. No.
Do you want to do it? It's a fun, wild ride! You learn a lot. Appreciate old school technology. Looks and sounds awesome.
If your car is your hobby, then you already know you can do anything you want to it.
