I would think it would be more "peaky". since the power band is smaller... hit the shift early or late would have more of an impact on your et than a slow steady 440...but that's just a guess. I had a nice 383 dart that ran low 12's. I know if I hit the shifter at 6500 instead of 6800 the car went slower. Seems the 440's I've had have been more forgiving. But as usual I could be worng,
