Holley or Carter?

Hey guys, I dug into the fuel system on my '70 Fury 318 and got a surprise. It is supposed to have a Carter BBD #4895s on it. The 4895s is very specific to my car...Federal emissions AT and A/C. Instead I found a Holley 2280 which was a dealer replacement carb sometime in the late '70s or early '80s. It is not in great shape and the car runs really bad because of it I think.What is everyone's opinion of the 2280? I don't find much mention of it and some rebuild stuff is no longer available....
