    Has any one , running in this class done my Doc dual plane mod to their intake???? Seems like this class would be all over that mod.... some nailhead guys have tried it and it makes a solid .2ths difference.... or does the rules prevent this??????

    It is a modification that I came up with late one night that makes a stock cast iron manifold flow better but does not look any different from a ordinary intake , unless the carb is off the car.... go to Da Nailhead thread and look at the sticky there... I have done this mod on all my cars and it makes quite a bit of difference in power....

    I would bet that they do - I think some BBB cars in FAST are running the "Gessler Shoot Out" intake, and by the photos it looks like pretty much the same plenum mods. Cant just be Buick guys...
