    They don't allow Strut cars so the fords get screwed in the end.

    Ford guys should be foaming at the mouth with these rules. Even if you mill down the 487's.....it won't come close to a 351w with GT heads. Those heads start around 60cc's and you can mill them down farther than that. Not too mention they will outflow any stock GM casting.

    Sure would like to watch the arguements in the tech area.
