There is an Ed Pink YouTube video that shows the Singer 4V’s and tells you that they are produced off premise but receive 8 hours of further machining at their shop,

Must be a bad picture or the wrong engine. Singer would not advertise 4 valves if there are only 2.

Different engine. That’s the normal 4.0. Williams builds the 4V engine. I read somewhere that the valvetrain cost $30,000.

Good catch! Did not realize Singer had multiple motor configs.

It would be fascinating to see the difference between the Williams / Singer 4V and what Porsche had designed with the 959.

They are 2 separate models, the Dynamic Lightweight Study "DLS" of which there are only prototypes at the moment (if I'm not mistaken) and the "regular" 911 restoration of which they have delivered 100ish customer cars (again if I'm not mistaken)
