FINALLY! I've been trying to register for days! (Maybe its some kind of initiation?) Anyway, glad to be here and hope to get/give good information. I have a 62 1/2 ton lwb fleetside I'm building ground up. It came from the factory with a 261/4spd. Have finished putting the engine together with 51bolt help after machine work and have an M4F cam installed. I have the option of using stock 261 carb, intake, exhaust or offy 2x1, fentons or combination. I've read about dual holley-webers but wouldn't a single h-w or 32/36 weber on the stock intake with the fentons do O.K?
