    Block is different. Double drilled exhaust ports for one and I think maybe Siamese intake ports. The size of the HS orifice is not the only thing that decides how much fuel the engine get at WOT. The nozzle determines fuel flow also. Like Gary says you can’t under estimate the importance of the thru hub exhaust either. Tremendous advantage in horsepower development.
