This is a used tunnel ram top for a Offenhauser tunnel ram to put a single Dominator 1050 or 1150 cfm carburetor on a big block. There is no part number on this top. Just to make sure, measure your manifold to see what the distance is between the bolt holes front to rear. This one is 9 5/8". Comes with a dominator gasket as can be seen in pictures.
