i have 4 340’s or blocks in my possession. Maybe these match your car: 1. Cast date 5/31/72. 3C266933. Bare block. .060 over and gouged. 2. Cast date: 1/6/70. 0B246071 FW340 P31050168. Bare block 3. Cast date: 6/1/72. 3B137370. Short block. 4. Cast date: 1/21/71. 2B112925. Complete motor (destined for my 70 Duster). I’m not looking to sell, unless it matches your car VIN. I would sell #1 block but it’s really only good for a table or door stop.
