'69 Camaro, Possible SS396?
 

Tougher to tell which engine it was ordered with on a factory air car, but the AC line configuration looks like the correct BB type. I would guess a build sheet would be present on the tank, being a Van Nuys car....

Solid car with a couple ugly floorpan patches, but looks like an easy project.

The poa valve is mounted inboard on big block & outboard on others (near the hinges)...Joe

Per the eBay ad wording...."the vehicle is driveable." Not unless there's been some work done since the pictures were taken.

What is that rad originally out of, a truck?
