OK, I stared at the '67 Factory Service manual for a while and I am pretty sure that's a smog pump base bracket bolted to the front of the RH head.
That's would make this a roughly 1 of 1500 or so 400 model built for California.
I also noted the empty holes for a console clock. Other items after a quick pass through the photos are the trunk being way too light a shade of gray splatter, aftermarket exhaust w/o a cross over, and the aftermarket power antenna.
Nicely optioned.
What's that small metal can mounted in the lower middle of the LH inner fender in the engine bay?
