Anyone know what this is?
 

 
Initially I assumed it was a typo and that is was a 1989 (or 8). But then I looked at the actual photo and obviously the exhaust manifold and throttle bodies are mated to 'wrong' sides of the 'V'.... which would have made kind of made some sense in 1982 as it would clear the venturis - but this would not have been relavent just a year later...
 
But there are a couple of reasons I'm not convinced?
 
1: It looks a bit modern for 1982 to me? 
2: Why would an engine manufacturer be considering a 3.0 as late as 1982, as by then the turbos were clearly the better option?
 
I know Alfa made a V10 in 1986-ish that was never raced (but did end up in their Procar). I assume prior to that the difficulties a V10 configuration creates with balance meant no one bothered. Unless Honda did?

1.5 litre, not 3.0 litre.

 

It's Kawamoto's 'Sasatsu' prototype 90 degree V10 from 1982, and only one was made. A configuration experiment that was dropped because it was impractical to incorporate turbocharging on it.

That photo is very confusing. Wide angle weirdness? The closest inlet trumpets looks like it is way back relative to the crankcase.

Don't know if these images will show up, but - if you can see them - they might help explain perspective:

Very odd looking engine! Like a V8 with two extra cylinders crafted on!

Or a V-12 with two cylinders cut off. . .

A 90 degree V12?? That's even odder than a 90 degree V10...
