Air cleaner looks good, correct snorkels, should have a flat bottom. Correct 696 alternator for a K66 (L Dec. date) equipped car. Interesting about the distributor. The part number 1111137 (M Dec. date) on the band points to a 396/325hp engine. It's possible a mix-up on the line happened??
He was looking for an idea on price. I was talking to a buddy who knows the '66 Chevy prices really well. He was saying around 40-45k. It'd be nice to see a picture of the stamping on the engine pad.
