That is a Ford Mako V8 Capri. I do t know much about them other than they had a Boss 302 wedged between the fenders and did 0-60 in under seven seconds. I know that because my father is using that as a bech mark for his five litre swap Capri.
Apparently they used cylinder heads from the Detomasa Mangusta. But some facts are probably getting lost in translation, literally. I can see pictures of the car in an old German Capri book ( I think its called Capri Bucht) and there is a picture of a Mk II with a shark on the grille instead of FORD. Obviously I can't read German or I'd have figured this out by now.
