4 more cylinders and better weight distribution....win/win
This combo would also be a C5 owner's wet dream. SC it for reliable 500 HP and leave the rods put.
And the oil-filler cap is a chop and tig job lol.
Since the clutch and BH adapters have been worked out, my next 928 hybrid will also be a Toyota DOHC powerplant.

Most Jags with SBC V8s are worth more than original examples. Just not that one.

have a 96 Q45 at almost 200k and it pulls like day 1...makes a good noise, doesn't leak a drop.

it's never needed anything but filters and oil, and a knock sensor (lost to a rat's appetite for japanese wires)

Ptuomov the link you posted to the "fronpower" v12 e34 bimmer is a bmw engine. His car makes around 1000hp. Awesome thread with google translate. The funny part is, that bmw engine is hopeless making much power N.A. because I'm pretty sure they used Ray Charles to design the exhaust ports.

Yes the vh45 is the strongest and best designed v8 I have ever worked on.

Back to the subject, uh yeah modifying the filler cap is a cake walk. Is it very tight on hood clearance or ground clearance with the pan? Plans for the intake?

The interesting thing is it seems like it sits further back than the V8. Which is usually a problem with V12 swaps.

I owned a 4.2E coupe 45 years ago,nice in their day, (their day, and mine is a long time gone) If I could find a good rust free "E" shell cheap (HA!) a toyota 2JZGTE vvti , twin turbo, with decent brakes and power steer would be my choice for a Frankenstein build.
Resale value? Who cares? if you are worried about day to day value, go buy a "park and polish" garage queen. transplants are a fun hobby,and every now and then someone hits a great combination, there used to be a crappy little English sports(?) car called an AC Ace, their value escalated a bit when a Mr. Shelby dumped a V8 down it's throat.
There are still far too many 928s (and E types- despite the prices) out there for them to be considered rare,
Go Dinsdale ! do it! result could be magic! Engine technology has improved by huge leaps and bounds since the 928 first rolled off the production line,
The 928 ain't the holy grail.it's OK to light a fire under one.(or three, or 10)

As think this out, if Porsche really put a V12 in the 928 in 1980-1982, this car would have been beating up corners with the 512BBI.

Doubt it, remember the "target" market for the 928 was the owners of the Mercedes SEC and Jaguar coupe.... at least by the time it was released that was the marketing plan.

Those V12 Jags are not fast by any stretch of the imagination, they are glass smooth, when they are running on all 12.
