68 340 engine WiW?

I have a 68 340 (dated 6 -67) engine im gonna be puting up for sale, this engine has serial number stamped nor does it have any stampings below the left cylinder head. Its .030 with forged pistons. I believe the crank is 10/10 , X heads with hardened seats. Any idea's i can't post pics as of now cause im at work. Any thoughts?
