Hal. How are You doing? Like I said, The buyers at auctions only see the cosmetic aspect of things.The owner says it is a 427, It could be a 402 with 2 bolt mains and bored over. I would want the receipts and parts lists. They just have money to burn. My car could could sell for around $100,000.00 if I did a frame off and restored it to original. I will never sell it so I do not care. It has the original receipt, pop, and color. It will look like original except for the wheels and tires and original suspension. I put Mickey Thompson wheels on it after 69 winter was over. I still have them. NICK L72
