1969 Chevrolet 350 Hn 300 HP Block 3956618 Date Code C-17-9 302 Dz Clone Block

  
Piston stamped 10, measures STD at top of bore. Has a thread repair on passenger side head bolt. Crank seems to be STD/STD. A nice period correct block but could also make a DZ clone. I will strap block to a pallet and shrink wrap. I will NOT deliver to home address.
