Welcome to the board. No initiation here, the moderators must have been busy with their real jobs.
The carb setup will be okay, but that's about it. My friend built a 261, full race cam, ported and shaved head. He started with dual Rochester singles, wasn't happy. Then we put on dual Webers, runs far better and faster, but he thinks he still needs more carb. If there was room under the hood, we would put on triples, instead we're looking for a cheap 4 bbl intake, and will try my 600 Holley on it. Your engine won't need quite that much carb, but I think you will be happier with dual deuces.
