What a sleuth. I got off the trail because I am now suspicious that I may actually have a 2007 4.6L in our work fleet...
My field crew will hardly notice the difference in HP. They shouldnt be using full HP anyway. May be some midnight service work coming up.
I will check back in tomorrow if I get time.
Thanks for staying with me on this.

I found the same part on FMC fordparts.com and it has the same horizontal front facing inlet on it. Whats up with that? Is that the plenum built integral to the manifold? So the TB would bolt directly to that face?
$457.90 MSRP
Is there a way to post a pic on forum messages? Would be useful to point out what I am talking about.

The local Ford dealer quoted the same price and said that was for the whole assembly, including plenum and TB. I am not believing that yet, as he showed a pic of those two parts being bolt-on pieces.
My field manager's truck is a 2007 4.6L and I will compare the connections to see if there is a reason to get the whole assembly. If it is a like for like match-up, I may just rob it from his truck which is getting pushed downstream to the field crews. May have lucked out there. 17 extra HP found sitting around in my parking lot...

Just checked. $199.00
However, he thought there might be some fit-up issues with the inlet port, such that I would have to get the plenum elbow as well. I need to check out the fleet vehicle and ensure I am not wasting $$ and time.
BTW - he mentioned I have a VIN#W series. What is that all about?
Nevermind. I decoded it. I guess there were two different series of F150 4.6L Series 6 and series W. Hmm. Okay, I change my question. Whats the difference between the two?

Havent figured out how to effectively post pics on this forum, so I attach the above link to show the differences in manifold assemblies between the 2003 and 2007 F-150 4.6L engines.
Both pics were taken standing square in front of the engines. The TB for 2007 can be seen to be pointing at 5 o'clock. The 2003 is pointing square to 6 o'clock. (The CAI is skewed however.)
Also, the 2007 is ALL plastic, including the plenum elbow which didnt even appear to have a bolt on connection - perhaps the reason Ford sells what looks like the whole thing as a unit. The 2003 is ALL aluminum? Cast something, but not plastic. Plenum opening appear of different size, but couldnt tell the shape of it (oval or round).
It appears the 2007 has a cable-less accelerator. 2003 is cable activated. While this wouldnt normally be a problem, with the TB at an angle, it would be difficult to make the stock cable bracket work.
Dang. Sure seemed like a silver bullet...

The 4.6 may be different, but the only year the 5.4 had an all aluminum intake manifold was in 1999!
To post pics,
right click on pic,save to your computer, upload to photobucket.
Scroll over pic in PB,a drop down menu will pop up under pic, copy the very bottom link, past to forum.
03 4.6 intake
If the 03 4.6 is all aluminum, it can all be ported.
07 4.6 intake

I clunked on the 03 intake and it is definitely not plastic.
Forgot to mention that in appearance the 07 manifold has a noticably lower stance than the 03, confirming its more car-like HP short tube approach. It is hard to say how the intake elbow compares as the plastic would be so much thinner than the aluminum cast 03 elbow. But looking at it, it has quite a sharp turn at the throat.
All in all, not a very attractive top end, but must do the trick.
Thanks for the photo instructional.

Well, I havent given up! In prep for what I thought would be a potential intake manifold upgrade, I started a search for a tuner in our area. Turns out the closest one is 100 miles away, but we started a discussion that may produce some results. He had adapted this edelbrock manifold to a 4.6L truck engine, creating an adapter for the lower plenum:
Edelbrock 28385 - Edelbrock Victor Jr. EFI Intake Manifolds - Overview - SummitRacing.com
He said they gained 39 HP over the Trickflow manifold that he started with (he's a Trickflow dealer), although he didnt use the TF heads. He had ported heads. He also ported the inlet elbow/plenum as well.
Could be an interesting project ahead...
I went ahead and installed an E-fan today. Had to do something! I also ordered a Cervini ram air hood and intend to duct it to the CAI in anticipation of more intake capacity!
Fun to be back in the modifying mode.

So my next obvious question was, how to mate up the stock inlet elbow to the Edelbrock IM. The same fellow who put me onto this latest trail also said that adapters were showing up on e-bay for this application.

So far so good...
