Tunnel Ram setup for the street

There is one mod I recall if running vac. secondaries: and that is to run a tube to each diaphram to ensure they are opening at the same time (synchronized). With multi carbs, everything should be synchronized and balanced with ports and certain aspects having a common source or connection. These are really fine points for optimizing a system. For limited street use (car shows-cruising) a lot of this can be skipped for awhile as you can put up with a few things when you are not driving a car everyday. My suggestion of 600, 1850 Holleys was based on the cost and availability...as pointed out by ds1, only $30-$40 is a cheap setup, not best, but cheap and workable. Any intake brand is OK. I just point out that taller longer runners, like found on the early rams from inception (60's) to 70's I always understood as prefferable to the pro-stock type of later years. If I remember, there was a street ram made around the time of the pro street craze of the 80-90's, but since you are making a period correct piece, I still feel the old rams look and work best on that vintage of car.
