Bizzarrini 7 liter Ford V8 original period,not recent creation

I used to have pictures of a kind of ugly Bizzarrini GT5300 Strada shaped car that had a 7liter Ford in it.I have heard a rumor that some employee left Bizzarrini and somehow got a body and chassis and sold it to someone who installed this Ford. Or anotehr theory is that Bizzarrini had an outside supplier and they kept the car to pay for work completed. Whatever, this is not the very rusty (I know the bodies are usually fiberglass or alloy but it looked rusty) that was offered at an auction a few years ago uncompleted car--that one looked more like a stock Bizzarrini and maybe it was a 7 liter Chevrolet engine in that one. The pictures were black and white and showed two small round taillights at the back, pointed ones like on the back of a 250GTO. The side vents were not the vertical ones chrome plated but large inset panels like on a '60s Corvette but two per side.

 

Could be a few different cars, Bizzarrini built a Big block Ford powered car for leMans. Then there was the NEMBO it was big block Ford powered. And a few got 427's or 454's, so which one is it? Pictures? You sure it wasn't a Ford powered Drogo Ferrari?
