Re: L78 396/375 HP Long Block CKO Stamping
All I really knew about the motor is where it sat for almost 20 years. I thought it would make a real neat warranty replacement motor for a 1969 or 1970 car but it never got used. I sold it for my buddy about 3 years ago then last year I end up with a LA built SS396 Camaro that I think is a L/78 but with the wrong motor in the car. If Jason's motor came out of a boat and this one looks as if it was in a boat before it was put storage. Is it possible that these were installed when the boats were being manufactured? If I remember right Mercury marine used a LS6 crate motor later on in boats. And that might help explain the additional stampings on the pad. The motor I had did not look to have been apart and still had the factory GM / TRW pistons plus the hone marks in the cylinders.
