I will assume you are replacing the tiny two barrel on the 318.
You will have to buy or fabricate the throttle bracket, since the original is in the wrong place., and if you are running an automatic, some tweeking of the kick down linkeage will be needed.
As far as the carb, it should be in the ballpark as far as jetting, the factory jetted them lean to begin with, for emmisions...
Just plan more fuel stops ! Not that the carb will burn more fuel, just your foot will be listening to the music more often ! 
yeah i'm replacing the 2bbl carb with the 4bbl that came with the intake, so its whatever came on a 340 in 1972. I'm pretty sure it needs rebuilt cause it was sitting in this guys garage for a long time and everything seems dry rotted, like its been sitting for 20 years or so.
about the bracket that i'll need for the throttle linkage and kick down...it looks like it was attached to the carb. i'm not looking at it at this very moment, but i think it was all there. will i still need to fabricate or will the 340's linkage and brackets work?
