Good point, Mike thanks. My concern and the reason for the big carb in the middle was that the manifold is actually two separate "logs" that are only tied together with two small hoses I would imagine to smooth out cylinder pulsations. The carbs will be set up with progressive linkage, and my concern with the small carbs would be whether or not a small center carb would be enough to "carry" the engine till I get into the end carbs. I do have (someplace in the shop) the tap left over from the circle burner days with Super Mods on carbs to convert from Rochester jets to Holley jets, so dialing in the end carbs will be much easier. If a small carb in the centers equalling roughly 600 CFM would carry the fuel needs til the end carbs are in, then tuning would be much easier..... Back to the desk top dyno, I guess. Thanks for the input.
