'70 340 shortblock
Casting # is;2780930-340-7, number stamped on right side lower pad is;0B299611, serial # on left side of block by head mounting surface is;340P 1070548. I found a 360 motor that I can use so looking for a reasonable offer on this if you can use it. Otherwise, I'll cover it up and put it back in the corner of my garage for a future project.
