Dan,
How did they change? Did you hold up each and look at a visual comparison? I'm interested?

I have an 03 and supposedly have the HO manifold.(starting in 03 they put HO manifolds on all 4.7s) Mine looks exactly like the 04 HO manifold pictured in the above mentioned site. From the ribs on the runners to the bar code sticker on top they are the identical.
Could they look the same but be different?

I'm not too sure. Mine is an 02 and has no ribs so yeah u could have the new HO intake. I haven't had a chance to look at the 4.7s onthe daks on the lot. Buit they still rate the 4.7 in the daks at 235 so it must be the same hp rating..or not the HO intake? Not to sure..

Hey Jeremiah what's up?
Looking at that link from Dan, my '03 has the ribbed intake as well. That site says the 03 and 04 models use the same intake on normal and HO 4.7's. Cool. One less thing to change!

And y'all thought the ho intake added power, I argued till I was blue that it didnt do much, for all you who claim it still does, then why no change in the 4.7's stats for 03 and 04 with the ho intake on their?

Cause they didn't want to do the paper work.
And peak power doesn't mean anything... Not like the powerband...

It may add power to my 02 dak. ince I do not have the HO intake. I plan on doing HO cams and intake a 68mm Fastman TB so that should be a good combo

The general opinion is that the HO intake shifted the power band to a slightly higher rpm than before, at the expense of low end.

My stock 2003 4.7 seems to have good low end and great upper end as well.
I was considering the 206 cams, but heard that coupled with the HO intake low end is sacrifced. Forget that noise. I'll stick with the plain HO cams swap. Plus they're not a regrind.

My low end didn't suffer any with the H.O. intake, but I also have the cams and the Fastman 68mm tb and relocated the IAT sensor, plus cut out the third cat, but I can say when I added the cams and intake before the other things, I didn't feel a loss in the low end, only a gain.
The Fastman is what made all the difference, I wasn't seeing much improvement until that was put on, then all the mods came alive after that.

I guess my 2003 Dakota also allready has the larger throttle body as well.
I guess I just need the cams. I just want to make sure I keep my low end for the times I tow.
I'd change my gears from the 3.55 to 3.92 but I've got a 4X4 and I'm sure the cost is doubled or more!
I've swapped gears on my own once and it was ok. But NOT on my daily driver or something that towed. I'd need to PAY for it to be done on my truck.

Hey GraphiteDak. I'm switching from 3.55 to 3.92 on my 02 dak, and i'm getting it all covered under warrenty. But I guess thats the perks of working at a chrysler dealership! The tranny guy at my work, is just going to get the 3.92 gears out of another ram or dak under warrenty, even though it doesn't need it. And just show that he did put them in, but didn't u know. Then I'm going to say my rear end is noisy, and the abs light is on. So then I get my LSD unit replaced, he puts the new gears in, and i get my rear end serviced all for free, which would cost me almost 1500 bucks. Just thought to give u the idea. If u know anyone at a dealer

Hey GraphiteDak
2001+ had the 68mm throttle body (not like my little 65mm on my 2000) so you're right about that.
I've got the 206 cams in my 4.7 now for a month or so, and did the HO intake manifold the following weekend. You do lose some low end, but the 206 cams aren't a ridiculously strong top end cam, they're designed for midrange power mostly. from about 2500-5000 the truck pulled noticeably harder than where it used to...and even if you drive like a grandma, you will be hitting 2500rpm usually. I wouldn't do much bigger a cam if you tow, but if you like to speed around sometimes in your truck too the 206's shouldn't be bad.
I should be dynoing the truck again in January, unfortunately the only previous dyno numbers I have is from LAST January when the truck was totally stock minus the belt fan and plus an 360airintakez.com intake, but this January all I'll have added is the HO manifold, 206 cams, and ypipe-back exhaust, so that will still give you a pretty good idea, if you can wait that long. It's only a couple more months ;)

just to clarify i meant what different effect will the new 04 ho intake have in comparison to the older 02. For example does the new one strike a better balance between increased top end and loss of low end, increase top end even more at the expense of low end, etc.

Cool Waltherone. I'd like to see someone with similar results. And Dan, I really don't have that kind of a connection at any dealers. Damn what a DEAL you got!
I may go with the 206 over the HO (200) cams if they don't kill the tow grunt that bad. Who knows. I may play it safe and go with the 200's. I wont be doing any of this until at least next summer if not later. The truck IS still very new and under waranty and all.
Now. People have mentioned that these changes were made on the 4.7 over the last year or so. The 235 HP rating was with the original set up. Now it is rumored that our newer 4.7's could have more power than that and maybe Dodge just didn't re rate it?
Would be cool if that's true. It's kind of like I allready got a few mods under my belt that I didn't have to do LOL! (The bigger intake, bigger Throttle Body, etc)

Saw another recent post on this topic, and have an update that might interest some. I have a 03 QC 4.7 4x4, manual tranny, 3.92 LS, Fastman TB, HO cams (and intake, keep reading), Gibson 3" catback, and IP PowerShot air intake (routed for genuine cold air, another story).
When I took delivery in Dec 02, almost immediately installed the HO cams and 02 HO intake, not knowing that supposedly 03-04 4.7s had a new HO intake manifold already. Nice improvement, but did notice some loos of low-end grunt/torque. Then came a couple trips to Afghanistan, Iraq, and points thereabouts - just this week got the time to remove the 02 HO intake and re-install the 03 HO model (verified by http://www.wjjeeps.com/ho_engine.htm link in this thread). BIG difference! Same power on the top end, but low and midrange is vastly improved. Wish I had a dyno nearby to check numbers, but butt-dyno is all I have - but the difference is very significant. Hitting the throttle in turns, starting from dead stop, etc., with the same clutch release and throttle as with the 02 HO intake will now break the tires loose, and getting this beast to spin both rear tires is now VERY doable - had to work at it before. Wish I had more science to lend this topic, but thought some might be interested anyway. Advice - go with the HO cams and 03/04 intake - big grins await!
