Hell I'd never get to use it all I ever get paired up with is harleys and a challenger now and then. Ifeel real bad for them for about half a second then I just turn my mirror up and forget all about them.
That airbox was in my possession lol (long ago sold). I would not normally suggest this type of setup because it's above the carbs that fuel based on airflow. I think it can be made to work but you'd want to go in with it very rich as a safe starting point. The intakes are a far better solution.
