Big blocks at the Tonawanda engine plant 1969

Look at the side of the bellhousing -- the entire thing is orange other than the trans-mount face.

Somewhere I have saved a color photo of a line of these racks in the storage bay at a car assembly plant, and it is very clear in that pic that the entire bellhousing is orange (other than the trans-mount face), AND the entire exhaust manifold (on the side you can see in the pic) is orange.

Somewhere online is a video (or maybe a series of photos, I can't remember for sure) of engines being sprayed on the paint line at Tonawanda, and it confirms above as well.
