Not quite the numbers I was expecting but they are numbers.
245 whp and 291 lbs of torque.

Its not a totally "apples to apples" comparison, but I dyno'd the 4.4L DOHC V8 from a '99 BMW 540i 6-spd I once owned, and it made 262 whp (on a DynoJet 248C). I figured the VH45 would be pretty close, as the BMW M62 is rated at a nearly identical 282 hp.
On another note, I purchased a VH45 last week. After being inspired by this thread we're going to attempt this motor swap into a BMW E30 chassis. Got the motor back (its in pieces - mostly going to use this one for mock-up purposes and will get an assembled/running VH45 if this one fits) then weighed it and measured a few things. Here is what we learned:
The motor and all accessories weighed in at 514 pounds.
Engine width was 28" wide at both the cam covers as well as from the alternator to the oil filter.
Zmech - Did you have any issues with the alternator or filter hitting the frame rails in your 300ZX? If so, did you relocate either?

Let me just say from one crazy person with lots of time to another, great job. Its good to see so many quality swaps coming along and yours is money!!!!
As per your dyno, i remember the same disappointment, because it feels faster than it says on the paper doesnt it? However in your case i think you have another problem. The knock sensors are notorious for dropponig lots of power on these motors, assuming youve checked these and know them to be good, here are a few places i think you can improve, the headers seem a little restrictive plus the cats arent helping either, ( i know you probably require them where you live), and the exhaust looks to be 2.5 from the pictures which seems good, but 3" is where its at.
These motors really like to breath, and the most you can do that the better off your gonna be, for reference heres my dyno run, granted this was on a 100 degree day in miami, in the winter months the motor put down a solid 295whp with the tuned ecu. The only differnce between yours and mine are the headers and dual 3 inch exhuast.
Of course you could always supercharge it like i did, and make gobs more power, but the above mentioned things will still hurt you there as well.
Once again great job, let me know if you need any info.

It seems Z's and AR's should come as a package deal.
Well yeah. Thats why I need a rollcage, so I can bolt a gun rack to it.
Everybody knows WHY we have the 2nd Amendment, right? Who exactly did our forefathers see us needing protection from? Our own government.

Loving the swap man. I've been mulling over a vh45 swap into my 280zx for quite some time. I think this summer I might actually begin to tackle it.
How difficult was it to graft the vh harness to the z31?

great swap - I've got a VH45 going into my 240z, and I'm running into oil filter and mount clearance issues. what did you do with yours?
