6-pack intake manifolds

DC 340 said

I clearly see the center carb for 340s but seems to list only outboard carbs for the 440. I wonder the difference and whether one of those outboards can be used on the 340. I barely remember reading somewhere they were jetted differently. Anyone know?

I’ll be using a 440 outboard carb since at the time I got them, they didn’t have the proper 340 rear carb that has the distribution tab in the passenger side barrel. Also, my set up is going on a 372 (+?) CID engine with a ported aluminum intake & heads and headers and etc….. so for me, it wasn’t a big deal at all.

Correct, just jetting AFAIK.
