All the old hop up books state that dual carbs are the best set up for a road job. I'm running a 3x1 set up on my old 47 but have blocked off the front and back. The tripple was best used for all out racing and now with all the good old carbs getting so worn out and so very hard to find it's even more difficult to get them running. While they dont look 'old timey' I really like the pair of Holley/Webbers from Langdon's and Tom will help you if you need bigger jets etc. Check with Langdon's and Patricks for manifolds etc.
