This 1957-1958-1959-1960-1961 Chevy 283 2x4 BBL Intake Manifold is an original GM# 3739653. The intake has been cleaned up and the baffle was removed, cleaned, and correctly re attached. The threads have all been chased revealing that one of them is a little loose but still holds. The previous owner did not use the washers when tightening it to the block so a few of them are indented (see photo). One of the holes looks like someone cut into it and will need repair (see photo).
The item photographed is only a sample. Your part may look slightly different than the one photographed but it will be the same quality.
