  • Engine: 1951 6 cyl engine head

    Is the head and manifold on a Studebaker 1947-1951 6 cyl engine the same?

    Pretty much, save for (possible) difference in compression ratio. Check your head and any replacement to ensure you don't put one with different compression ratio then is supposed to be on yours. That is, unless you actually intend to decompress, or ramp up yours a little????

      Brand New 1960 Lark 170 Heads are available, that would bump up the Compression at least one Point to 1 1/2.
      If the bottom end is strong enough, it could work fine.

        Rich, I hope you meant 7-1/2; not 1-1/2...?

          The manifolds are the same through 1952. In 1953 they changed the carburetor mounting base and carburetor design.

            No, it WILL bump up the compression 1 to 1 1/2 Points.
