    Have you ever heard that changing the firing order on a blown BB Chevy would be easier on #2 and #4 mains?

    Anyone have real life experience with this?

    Just go with the dual if you are going to swap any. Makes it run much smoother

    We did the 4-7 on both of the blower motors and carried it over on the turbo motor too. Didn't have any adverse reactions. JW
