Thanks for the info guys! I have been talking with a buddy that owns an exhaust shop across town that thought it was crazy to spend that much and he can do a 3"w/cutouts and turndowns for way less so I think I will go that route with the MW Manifolds.
The car does have Power brakes. . . Am I to assume the MW manifolds will interfear with the Booster even though it is a more narrow 361?

Hope I dont have to scrap the whole Idea, I love the MW look but not a necessity.

Would there be any benifit to bolting on the rebuilt set of '76 440 heads I have. (if only for the hardened valve seats)
