Want to install a 350 SBC in place of my original 283 and still use my front mounts. what'll work?
They do not even bolt up. Pattern is different.Also, a BB is about 2in longer than a SB. SOOOOOOOOOOO, if the bell housing/block mating surface remains in the same position, then the front of a BB is going to be about 2in further forward than the front of a SB. Thus, stock 55-57 front mount brackets will not be in the same position as they would be with a SB.
