Does anyone know what a Fel-Pro gasket number is for the carb to insulator plate? My local auto parts store has ordered 3 sets of gaskets and they are all wrong, either the bolt holes don't match or it covers the needle valve adjustment hole. | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | I don't have part numbers but that should be simple. They used the same gasket from 54 up well into the 80,s. There are various thicknesses. If it doesn't have a pathway from the power valve hole to the manifold vacuum you can cut a little hunk out of it.
They say money can't buy happiness. It can buy old Chevy trucks though.

Should be 2 15/16" center to center for a 235.
Sometimes a 216 intake/exhaust was used on a 235.
216 bolt center is 2 11/16"

The narrower mounting bolt distance would most likely be FEL-PRO Part # 9520.

Does anyone have any other ideas other than just cutting a hole in the wrong gasket? I know there must be a correct gasket out there somewhere.
