I have had very good results using pairs and triples of the Holley/Weber pinto/Vega carbs. Progressive two bbls with small primaries and larger secondaries. Very tunable. Just remember to heat the bottom of the intake. You will be much happier if this is a street motor. There is another Weber two bbl that Tom Langdon at Stovebold engine co. uses that may be a little better and easier to come by than the pinto/vega units. I ran a pair of carter YF's on one of my 235's. Had off idle issues and fouling until I heated the bottom of the intake with water. that helped a bunch.
