    For my whole life, for some reason, i thought a 364 intake was a bolt on to a 401-425..i thought they where the same width..im sure everyone knows the diff in early to late nailhead intakes are the width

    so..does a 364 intake bolt on a 401 i need to figure it out..because my memory isnt as sharp as i would like anymore..

    Had this info saved, likely from the Yahoo Nailhead board:

    322 Buick ... 364 Buick ... 401/425 Buick ... Each of these Buick engines has a different measurement across the rows of bolt holes that bolt the manifold to the heads. 322= 8 3/8" ... 364= 8 3/4" ... 401 and 425= 9 1/8"

    You can slot the bolt holes, but port alignment becomes a problem. But maybe you can do it with the blower manifold? I don't know what the inside of the blower manifold looks like.
    Last year I saw the Falcon with the blown Nailhead built by Chuckles Garage. You could ask them what they used.
