Thanks for the link Rob C I appreciate, however i can only find it for $87.32, where do you see it for $64? For $64 i'll be the guinea pig for sure!

Ian, I searched for it by going to 2004 Jeep Grand Cherokee>Fuel system>Fuel induction>Intake>Intake manifold and it came up as $63.79
I just went back to the site and tried to search by part number but, when I entered 53013403AD as a Jeep P/N, it came back with 'no parts found'. I then tried 53013403AC and it returned a listing for $63.79 I then entered 53013403AD as a Dodge P/N and it came back as $87.32
Sorry to get your hopes up, I didn't realize it was the down-level manifold that was listed for $63.79 since it didn't include a part number when I did the long search by vehicle and submenu.

All you need to install that on a 2000 4.7L is a socket or two, and a couple beers.

Update: Installed fastman tb and 04 manifold on my 02. Didn't completely take care of the pedal vibration problem I had with a tb upgrade on my 02 manifold but did make it somewhat less pronounced. Over time on the 02 manifold the vibe lessened, I'm hoping since the 04 manifold has less of a vibe to begin with over time it will nearly entirely disappear. I'll keep y'all updated.

Pittdawg, what kind of intake system are you running? K&N, Airaid, AirForce1? I read somewhere (probably on this forum) that some intake tubes cause a reverberation in the intake which gets transferred to the accelerator pedal via the throttle cable. It's especially bad with the metal tubed intake systems. Have you tried putting some foam insulation on the tube where it contacts your throttle body? This should reduce some of the vibration.

Well, if it isn't coming from the air intake then have you followed the path of the throttle cable from the throttle body to the firewall? Maybe your cable is routed incorrectly from the factory and is touching the engine somewhere. Who knows? All I know is that I don't have any pedal vibration but, I'm driving a Jeep Grand Cherokee. I'll ask my buddy with the 2001 Dakota is he ever noticed any pedal vibration.

Pittdawg, My friend's 2001 Dak is almost stock, Gibson cat-back and Airaid airbox mod. He's never had any pedal vibration.

Yeah its kinda of (bad) luck of the draw...talk to either Bruce at flometrics or Dan the fastman and they will tell you that about 1 out of 10 2000-2002 dakota 4.7's get a nasty pedal vibe with the addition of a larger throttle body, in fact from posts seen on this board and what not I suspect it is a slightly higher percentage then they are willing to admit, but on the whole it appears to be more uncommon then those without any vibe. There is much speculation that the newer 03/04 intake manifold was redesigned to address this very issue, I wonder how come you switched manifolds if you did not have a vibe, did you assume the redesign must have at least in some respects helped performance as well? I have only put about 35 miles on the new manifold with fastman tb and it does seem the pedal vibe is lessining with every drive, whereas before with my 02 manifold and tb it remained fairly pronounce although it did lessen a fair amount after about a 1,000 miles. I'm hoping after 1,000 on the manifold it will completely be gone. Anyways, how are u liking your new combo, how many miles you got on it so far, last time it took about 500 miles to feel a real big difference from the tb so I am excited to see, i already feel a slight performance increase just in these first 35 miles, can't wait till the computer makes all the proper adjustments.

I was figuring since they use this newer style manifold on the 2004 HO and standard engine, they must have found the right combination of low and high rpm power delivery with the new design. I also thought that it probably doesn't hurt performance or they would be using it. I haven't got that many miles on it with the new combination because I decided to do the Speed Tweaks TPS mod but, was thoroughly dissatisfied with the mod so, I reversed it and reset my PCM again. I think the new manifold doesn't add any dramatic power gains but, at higher rpm the power doesn't drop off as fast and at lower rpm the torque is still good.
So, the short answer is, I wanted more power. I don't know if I'd recommend the manifold swap to anyone. The gains are too mild, the manifold has cheaper construction and it may not have been worth the trouble or price for me. I guess it was a lot less trouble for anyone with a 2002 4.7L but, on my 2000 I had to buy a new IAT, PCV hose and adapters to fit the PCV valve and fitting to combine the 3 vacuum lines on the manifold into 2.
The Fastman TB was a definite thumbs up recommend. Especially if you changed to the HO cams.
I'll add an update after I get enough miles on the PCM to see if there's more power the PCM is going to unleash once it's finished learning the new parameters.

I just traded in a 2002 Dakota, cc, 4wd, 3.9, it's a long story.
Just bought a 04 Club cab 4wd 4.7, nice truck, totally different than a 3.9. I put on a manga flow, left the stock pipes with a tip, thats it there. Put in a K and N air cleaner in the stock box. I am looking at this design and see a great collector box to feed air into the tube. IMHO the bottleneck is the little tube running to the fender from the box. I say open that hole 1 inch and run 4 0r 5 inch elbow right to the fender hole. I haven't checked the actual diameter of that hole yet looks like about 4 maybe only 3 inches. The tube would be easy to make because you are using plastic pipe to replace plastic pipe, this would be easy.
Just got the damn think so it only has 220 miles on it. Sounds great, the magna flow runs quiet when you want it and still sounds great. Seems I got a little response out of this, but I am thinking the box modification is it. I am not sure if you can cut the hole 5 inches but get make it as big as you can.

ok I looked at my 04 intake. the tube into the collector box is oveal and it is definitely big enough ,looks like almost 5x4 oval with a healthy cone shape to the tube. I would say the stock intake is the winner. I haven't tried aftermarket brand because I am not sure it will do anything, the stock intake looks haelthy, Maybe replace the accordian tube running from box to the manifold. Use a smooth rather than accordian.
Anybody changing the 01 air intake yet??? What brand are you trying???

Update: 250 miles logged in on the new manifold tb. Half of what need to fully comment, but thus far, mid range power thus most noticeable difference between 02 manifold, low end maybe a shade shy of where it was with 02, but mid range noticably better and top end the same thus far.
