Transplant a 30v in to a 12v B4 90 and then supercharge it?

I'd rather just buy the A4 2.8 30v and supercharge it.

CQ + AAN is something more unique however. =)

mmmmm... I'm just surprised some weirdo has never done it... I'm sure there are some 30vs chillin'
and some 90s with blown engines that could get together and have some fun. I'm guessing there is more to it than a simple engine swap. I know next to nothing about the V6 90s.

What about just swapping out the 12v heads for the 30v ones?
Same engine pretty-well eh? So wouldn't the two heads be more or less interchangeable?
I dunno, that swap is something that I've sorta been tossing around in the ol' noggin.
ideas?
check yah later

Re: wonder if that can be done with a 200 10vt. -Is that an MC-1 or 3B block?
Where have you been? I've investigated this for a few years now ;-)
Short answer, yes. Long answer, not without a lot of work, as the 351N and 351B heads are not identical. The water manifolds are VERY different, the cams are very different. Also, due to differences in the combustion chamber volume in the head (20v = 46cc, 10v = 29cc) it will drop the compression ratio a whoooole bunch, which is way less than ideal when you are starting out with either 7.8:1 (MC-1) or 8.3:1 (MC-2). You end up with a 6.9 to 7.2:1 or something like that, depending on which 10vt block you use.
