I have a block i bought off my neighbor, he believes it was pulled from a 1969 chevelle. It is cast 3970010 and stamped v0726cub and 17j362667. I pulled the pan and heads, it is a 4" bore, 3.48 stroke and 2 bolt main. Any help identifying would be appreciated

Looks like it could be a 170hp, 350, from a 1977 passenger car, eg Impala, had 4 barrel and th350 automatic.
