No Drama, there is something terribly wrong with your setup, how much HP did your engine make? What kind of heads are you running? Are those carbs vacuum secondaries, if not have you changed the squirters, the jetting sounds real lean on the primary side, I have a built 468 with good square port heads on a 20' Glastron Jet which is close to the weight of yours I am running a holly 850 annular discharge carb which is jetted at about 80 square, with 50 squirters, and it runs very well, put up more info on your engine and maybe some of the experts can help you.
