I believe if it were otherwise you would have a slightly (or more) richer
mixture than needed for optimum running. In fact for optimum fuel economy
(more of a concern to the "Nova" Scottish than to the Gringos in Oklahoma)
you might want to lean it some more to where it is a little cranky till it
is really warmed up. But that hinders driveability, especially if the car
is mostly used on short trips. The cast arn combined manifold is friendlier
in this than the aluminum intake manifold.
