thought to be from mid to late 70s van or truck , its a "010" series block, stock bore now, none of the lifter bores bushed, hardly any ring lines in tops of bores,factory chamfers at face of block still present as cylinders never bored, cylinder bottoms don't show any hits from connecting rods, block on the right in the picture is the one I have left $500.00 firm , if interested e-mail me on the hotmail service at bigpig41 or reply through craigslist.
