A Chevy 8970010 is a 4 bolt main 350 cubic inch engine. It is classified as a small block and is placed in a variety of automobiles from sedans to light trucks.
I have a 1996 305, Vortec with that number on it.
I can't give you an exact year based on casting number alone because Chevy used that casting for several years from 1969 through the mid 1970's. It's one of the better (and more common) 350 block castings. It can be either 2 or 4 bolt main, depending on what it was originally used for. As long as it's in good shape, it's a great block to build.
