Name this engine!

While some of us are still locked down, or under-employed, something to exercise the bit of fat between your ears: Name this engine!

That is cool, no idea as yet. A flat four apparently

Are you taking votes? How about Super Bee 4OHC.

"Percival Cossington-Smith". (That's assuming it is English.)

Nice to see a degree wheel, threebond, nail polish, writing sticks and threadlocker...


Edit, the far left carb is missing a nipple.

Porsche of some sort?

Random Idea ....
Flat 4 cylinder ...
Old Subaru Boxer motor ?

Kiwirich

No-one's got it so far!

OK, looks mass produced yet somehow clunky. DOHC. Definitely Euro, not US, definitely not British.
Alpha Romeo boxer of the 1970's. Alfasud?

The orientation of the carbs is interesting, is it an aircraft engine?

“Name this engine!“

Call it Fred!

That dry clutch had me stumped, but was looking at the pic thinking it would have to me mounted longitudinally, or else why offset the clutch?
Good call.

Hrrmm.. it is not a car engine... Look at the small bottle of threadlocker.. Even an Alfa-sud engine is huge compared to this thing..
With the off-set clutch, and with the twin cam per bank it is a performance engine.. Not sure if it is mass produced though...

MV was working on a 500 flat 4 IIRC

Looks like it; https://www.motorcyclistonline.com/news/whatever-happened-tomv-agustas-boxer-four/

I think that you nailed it Donks, right down to the missing nipple

Or perhaps I should say ferrule.

I was going with Bruce but Fred it shall be

Heil Fred

Names smames, give us a go?
I promise I won’t crash it.
Hold my beer.
