I have a 70 LT1 block. I wanted to find the car but it has not surfaced. The last 6 of the vin look to be 529121. The block is cast on D 3 0. The ad stamp is hard to read. It looks like V0--0CTB. I imagine the first blank is a 4 and the second is a 1 or 2. I believe the car was in the Monterey Bay, CA area when the engine was separated from the car. Let me know if you know the whereabouts of the car. I would like to see the engine back with the car but will also sell the block outright for $1200.
