PJ has the correct name with the Saluki (shared with the 1971 Siva Saluki, plus the international export version of the Dodge Ram Charger/Plymouth Trail Duster, known as the Chrysler Saluki in some overseas markets - I've never seen the latter myself, but I do have a brochure on this version from the Middle East).
So, a point to PJ for the name, plus a point to Carnut for identifying this as a Chris Humberstone project.
I will keep this puzzle open however to that the remaining details can be guessed at (e.g. intended client, precise powertrain, etc.). Have fun!
