Double check the crank trigger wiring and the firing order. Do you know if it is a std cam, 4/7 or a 4/7 2/3 swap cam. Yo may also want to check to ensure the throttle blades ar not open to far allowing fuel from the boosters to get in the mix. Also might make sure the two cylinders with the clean plugs that appeear to not be firing are in fact firing....
