B body big block 400. All running gear is original. One owner, no rust and has never been wrecked. All numbers match. Interior is all original. All engine parts have been powder coated. Paint is original color and it was stripped down to bear metal and repainted. I rebuilt the engine at 62,000 miles and bored it to 30 over. It is still stock. I have only seen 2 of these at shows and car auctions. All original, but with few minor alterations.
