Super Six install on 1974 Dart

are you certain the two are the same?
i think more importantly the the position of the D shaped hole, is the distance between it, and the hole where the kickdown linkage actually attaches

this determines the ratio of the kickdown



as for the colder intake, i would see if an airhat from a dakota would fit on the 2 barrel

I see what you're saying, but I think the two are identical. Thanks for the tip on the Dakota part.
