Seen videos on YouTube, sure it was a MK.
Like most modern bike engines,tall engine so you need a massive bonnet bulge or the air box sticking out

In your case, I'm not sure the engines to blame for that

Compared with the previous motors they make less power but because of the way it's delivered (in the bike) it's more usable. Apparently
(according to those I've asked) they can get on the power earlier without it trying to throw them in a ditch. In a car that's not so much
of a problem and you've just got less power.
Not sure about the failure issues. That could just be poor build/conversion design putting it in a car... We'll only know that once someone
figures out a way to stop it happening and let's us know.
Like Tim says though, they sound amazing.

Good question Craig. I'd have sworn I'd read fairly recently that folks had suffered issues but I'm damned if I can find anything
now... As you were.

im not sure it would be so kind on the driveline , normal bike engines conversions can, hop out of gear, bang out the boxes or fail early if there is
no rubber crush to put a bit of give in the drive like a motorbike would have in its rear wheel.
a big bang fires in pairs to offer the traction of a big twin but give the near performance of a 4cyl in a bike
your putting so much more load buy putting a bike engine in a car and the bigger power pulses and gaps between are going to exadurate the problem i
would say?

A "true" Big Bang engine might fire in pairs but the R1 variant doesn't. It does have unequal firing spacing of 270-90-180-90 but
the cylinders all fire separately.
I'd happily use one in a BEC but I would make sure that the engine came with it's ECU and all necessary sensors etc to make it work as
not all aftermarket ECUs will be suitable.
It would have to be cheap though, to stop me using a CBR1000RR engine.

Which is why most BECs have a cush-tube in the prop'.
