Friends, lovers, Chevy cretins....Let's unf*ck a Six Pack

True, if you pull out the lead plugs.
I'm ok with this. The EPA didn't mandate this idiocy in my alternate timeline 1975.

Is it possible that the 340 is flat and the 440 isn't?
Post some close ups of the linkage, it looks like you have mechanical linkage on the vacuum setup
It's a solid rod, but doesn't mechanically actuate the outer carbs. It only forces them closed. Not sure why they would replace the factory linkage but since there's a bunch of new linkage sets on the market today, I guess that's common.
