How are you getting hands on that rare engine? Are you from Europe?
I find it a little hard to believe too but the offset angle from the pistons relative to the crank is 12mm in the 2.8 and 22mm in the 3.6 which should also help keep the package smaller. I have the believe it is a little longer due to the piston bore but if people are swapping them into other VW chassis' using stock transmissions and CV shafts then it seems to reason the blocks are very close to similar dimensions.

I'm in the USA, these engines are used in several VW products from B6 & B7 Passats, CC, Audi Q7,etc. I believe there was a smaller 3.2 developed but that was a euro only fsi motor.
