Well WRBSTI, where do I start...

Congrats to you:
I like the idea of the 4.6 Northstar - 32valve Quad Cam
Seems to me that the LH2 series may be a good option, as they produce 320HP out of the box (and a reasonable tuner may get 360-370HP easily), and torque to match! AND these are known as "quiet engines" - BONUS!
Most Northstar Series engines were reliable, provided the original PCM module was used (the one with the limb-home mode....!).
You should be able to maintain 4WD on the VX and the TOD system!
The LH2 was already setup for longitudinal mounting (RWD/AWD), rather than the LD8which was a transverse mounted engine for Front Wheel Drive.
This may also greatly help with the Accessories (A/C, Power Steering, Alternator, etc) - could make the job a lot easier!
The L37 - up to 300HP with 295ft/lb torque - good engine, but get the later version (after 04) with the later PCM (see below).
The L47 (aka the Aurora) is the heavier version producing less power/torque with less displacement (4.0L) was made for Front Wheel Drive..
The Northstar Series feature CHAIN driven Cam Shafts - brilliant
The LH2 also featured the VVT on both intake as well as exhaust cam-shafts, and if I'm correct, like the 6VD1/6VE1 individual ignition coilpacks on each cylinders.
AND (good for emission control) the standard configuration runs a Wasted Spark ignition program.
The GM PCM (Engine Management System) is programmable via a number of suites, such as HP Tuners (ask your tuner to confirm).
From my experience, the General Motors PCM is an excellent product, however if you want to "play" a little more, I'd personally go for the DTA Fast S80 Series.
NOTE: This may also help with DE-RATING the engine output to save the trans from blowing to bits - remember: about 285HP input is the rated limit -
Also, there are PLENTY of parts available, including upgrades, however:
>> I'd carefully size up engine/sump etc to ensure fitment <<
Here in New Zealand we have very limited access to the LH2, so once confirmed that these will fit, i'd be looking for one complete engine with the PCM so that I can finally give the beast the upgrade it deserves.
(The VX Should have been a V8 from the start in my books....)
Oh, before I forget - ask your local AutoSparky about the Alternator:
-- Is is water-resistant? (Everytime my Isuzu Alternator gets wet I'm in for $200 repair bill.)
I'm looking forward to the developments!
Live Life To The Max - Drive (and modify) a VX!
