Yes, the 10237300 is an old casting. The latest gm casting has a mechanical fuel pump boss on it. We (boat applications) are not the only guys who buy these engines. The muscle car guys actually want the mechanical fuel pump for their vintage cars.

Are all 3 of these blocks the same bock? I mean , I know a guy looking for a 10237300 Block . Did they quit making those? He wants a GM clock but doesn't want to put a frickin cover over an unesseary fuel pump boss. Seems kinda generic you can't get the real ch!t from GM
