we have a 555ci BBC in the shop right now it has a set of custom craft headers on it(custom made) they are 2.25.
my dad has a chevelle that has 525ci BBC on the spray going in it, it has a set of custom crafts as well they are 2.25 primary also that step to 2.5 and a 4in collector.KENNY DAVIS HOTRODS
