292’s also have the fuel pump behind the motor mount, 250’s (and 230, 194)have it in front of the motor mount.

I googled the casting number 473483, it's a 1975-79 250ci.

I don't know much about 6 cyl engines. My main interest is the 4cyl Chevrolet's from 1914 to 1928.

I have a complete '25 engine in my doodlebug,Presently stuck with atf and acetone in the cylinders. I am curious to its value as the doodlebug is just yard art and i would be willing to sell parts but don't know what the market for the engine would be.
