Greets!
Correctomundo! I started to mention this, but for a
variety of reasons, in recent years I've gotten to
where I just answer Qs. Anyway, the short of it is
that these mills typically need somewhat < 300 cfm
except for passing, etc., so relatively tiny primaries
are all you need. If I hadn't been in such a hurry and
the 2bbls hadn't been dirt cheap back then, I'd have
swapped to an Edlebrock/650 cfm spreadbore double
pumper combo. Today though, a much more fuel/smog
efficient carb would be required.
I've been away from cars for a long time now, I wonder
why the 2bbl cost more? They use to sell them as loss
leaders when I bought mine. Just looking at Jeg's:

the price is pretty much in line with what I paid for
mine once inflation is accounted for:

so can a decent 4 bbl/manifold combo cost less than
this plus electric choke?
