Why no numbers Thank you!!!

The title says it all. It must be a replacement of some kind.

66 PLY VALIANT: Believe it or not SB are not too easy to find in the Denver area. When you can, they tend to be a little $$$. This came with everything, even the headers. The Junkyard pulled it and loaded it my Van. Total cost $150.00. Also will be very basic. Don't want t6 mess with any kind of engine computer.
