That looks like a Ford motor.

Pinto Power! 😀   I have one sitting in my shop with a custom aluminum valve cover, Offy dual port intake topped with a 390 Holley 4 barrel, Racer Walsh cam, and headers.

What the hell is this?

 

Honda's attempt in the early 70s at beating 2 stroke bikes. Wanted a V8 rules said could only have 4. It was notoriously unreliable and only managed to complete a few races before they scrapped the program.

NR500 here.

 

Honda tried that to increase valve area, to get the benefits of a V8, while staying in the FIA regulation of a max of 4 cylinders.

Surface area was actually more than a 4-cylinder of the same displacement, with the same stroke.

They also had a prototype that had oval valves.

But unfortunately was a complete failure on the track....I think the engineer in charge of that thing is either sweeping floors at the factory now, or committed seppuku.
