My 2000 4.7 has 138 K miles and it runs better than the day one.
Back in 2000, there were 2 V8 engines.
The reason i got the 4.7 was the availability of 5 sp manual. It helps a lot when you want to loose traction for whatever reason that is.

I have 2 dakotas one with the 4.7 and one with the 5.2. I love them both, but the 5.2 has no where near the power that my 4.7 had when it was still stock and as far as gas mileage, its no question! My 4.7 got 21 mpg avg when it was still stock my 5.2 sruggles to get 16 mpg on the same exact route. (My 4.7 now still gets 17mpg with 4.56 gears running 2600rpms at 65mph)
Not trying to say any thing bad about the 318 but if i could have the same truck with a 4.7 i would definately have spent extra money to get it.
Having said that the 318 has an astoundingly higher amount of parts available and they are almost all cheaper. But it will take several hundred dollars to get a 318 to be as fast as the 4.7 is stock! My 4.7 now is good for 14.21@96mph and it it is an auto, the 5sp would be even faster with the same mods!

The 5.2 was developed in the 60's (origins may go even further back) and has been tweaked through the years. Yes its reliable but it has its flaws (cracking manifolds, leaking plenums, poor mileage, low power output for its size). .
As for mileage, my 4.7 Quad cab consistantly gets 20mpg on trips to Maine (up hill against wind) carrying luggage for 2 and a whole bunch of crap for 1 baby. It has more power, a linear torque curve, plenty of off idle torque, and was developed in the late 90's where technology was used to make the motor and it was tested thoroughly for hundreds of thousands of miles before being released to the public.
Go for the 4.7, you'll never regret it.

Say ron moorman, which one did you get? I've had Daks with both engines and enjoyed both. I put 217K on a '92 5.2, and have 162K on my '01 4.7. At the 160K mark, the 5.2 was using 1/2 quart oil every 3K miles on dino oil. The 4.7 uses NO extra Mobil 1 every 5K miles. You can't go wrong with either one. I think age/mileage/condition/price is where the selection is.

well after test driving both of them i bough the 99 with the 5.2l and 5-speed it had way more power the that 4.7l. i mean the 4.7l is fast but it all rpm and no pull. the 5.2l pulled all the way through the rpm range. plus i hosed the guy out of it! so what the first mod i should do to it i know ill have exhaust on it before next weekend whats a good sounding muffler/what produces the must hp & toruqe
my buddy has a shop with a dyno that's going to do stock numbers and after each mod i will do another dyno if it doesn't make a difference ill let you guys know.

That's weird that the 4.7 you test drove seemed to not pull hard. I wonder if it had the death flash or something?
My 4.7 always snapped strong from a dead stop. Even when I had the 3.55 gears. I always seem to notice the 4.7 had an identicle low RPM torque band to the 5.2 but with the benefit of 1,000 more RPM's on the top. It's funny how not all trucks seem to be the same. SOme can even be factory freaks, while some are just a turd!

Graphite said a while ago:
"Some things on the 4.7 are actually EASIER to work on than the 318 believe it or not.
The intake manifold can be removed without removing the fuel injectors. The exhaust manifold can be removed without removing spark plugs or wires (because they are not there). The Coolant t-stat can be changed in 10 minutes and no gasket to replace/skrape. etc etc
Also on a 4.7 you can enjoy revs to 6k RPM STOCK before shifting as opposed to a stock 318
With a SuperChips tuner I see as high as 7k revs. "
Not to sure about the intake, as i havent pulled one off a 318 before. Ive never worked on an engine that you had to take each injector off to pull the intake. even with that said, i yanked my manifolds off without taking the spark plugs off. The plugs arent even close to being in the way. I pulled and replaced my t-stat in about 10 minutes but ill admit the way the have it set up on the 5.2 mag is a beyatch. definately have us on the rpm end of things. but thats just kind of the way most ohc engines are.

I have the 99 318 and have never driven a 4.7. Going with all the talk, and not just in this post, I had the impression the 2 was pretty close in performance. I'm wondering if the 4.7 had 3.55 gears and the 5.2 had 3.92's. I'm 64 years old. Over the years I've seen a lot of new auto's. One thing is without question. Every now and then a make/model comes out of the factory with the ability to out perform compitition that it shouldn't be able to. Realizing all parts are the same in a given model leaves balance and fit. Here in lies the differance. If your lucky enough to get one of these perfect auto's. consider yourself super lucky. There few and far between. I have never got a new one of this caliber but I have managed to buy a couple of used ones that were impressive.

Wow there's a lot of hacking on the 318 going on here...I must have one of those "freaks" as GraphiteDak said. I test drove about 5 4.7 Daks before I got my 5.2, and they all seemed to have decent power. One I'm sure had a death flash as it didn't have half the power of the others. But my 5.2 I have now seems to pull all the way up to 5200 (they set the damn rev limiter at about 5300). I wouldn't say the 318 has any FLAWS, but they do have downfalls due to PISS POOR engineering on Chrysler's part. Like the Plenum Pan gasket. Old 318s didn't have this problem, it's the new manifold design. The 4.7 had the advantage of being desined from scratch. The 5.2 was designed in the 60s with traces to engines from the 50s. They just updated it with newer technology, not newer engineering. If Chrysler made the factory 318s and 360s with Mopar R/T heads and M1 intake manifolds, and with the Mopar PCM, I highly doubt people would be talking the sh1t they are talking about the 318.
The Magnum 318 and 360 were made during the time when Chrysler was obsessed with cost cutting, which is why they made the 318 and 360 with the same intake manifolds, rocker arms, cam, throttle body, exhaust manifolds, and heads. If they designed separate components for each engine, best suited to each engine, then things would have been much better for both the 318 and 360. Trucks don't need screaming HP at 6-7K RPM they need the torque down low for hauling and towing. Just look at chevy. They advertise their Colorado with so much HP and it can't tow sh1t. Same with the Frontier and Tacoma.
My goal in this post isn't to anger anyone. I never threw a single insult out at the 4.7. I actually like the 4.7 and I think it's a great engine. I'm just saying it's not fair to hack on the 5.2 saying it's a dog and is sh1t compared to the 4.7.

novaDAK - I didn't see anyone "hack on the 5.2 saying its a dog and is sh1t compared to the 4.7". Where did you get that impression ? No one is trying to put down the 5.2 when they say the 4.7 is easier to work on for some stuff (do a cam change on both engines and you'll notice this) or that the 4.7 makes more power and revs more up top - these are just simple facts; due to the engine's designs.
I noticed more wrong impressions about the 4.7 (like people falsly saying its a German design, or questioning its longevity). Seems like a lot of 5.2 guys seem very threatened by the engine's replacement. I'm not trying to anger anyone either, just some simple observations. Funny how peoples perceptions can be so different depending on which motor they have...

You're right, Kowalski; I don't know what the big deal is in splitting hairs 5.2/4.7. I was skeptical in '01 after having a 5.2 for 8 1/2 years, but the 4.7 is proving to be the more reliable of the two. If your Dak has a V-8 period, you are a winner. However, I am proud of the fact the 4.7 was the last Chrysler V-8 designed and built by USA workers. Some consolation with Diamler being sour on Chrysler.

"If your Dak has a V-8 period, you are a winner"
Said perfectly!
I forgot about the cam swap comparison!
I too had been around 318's for YEARS and always loved the Chrysler V8's.
As of the last few years my Bro in law who lives up the street has a 2000 RAM 318. We have changed his cam, he installed rockers, we did the belly pan mod from Hughes... etc
I have the 2003 4.7
We have replaced my intake (with a hacked modded one we tweeked with) and we just bent the fuel rail a little and left all the injectors and plugs in place. NO WATER comes out when you change a 4.7 intake :P
NO WATER comes out when you replace the 4.7 cams.
In fact. NO NEW GASKETS are needed when doing either of those things on a 4.7
SO I believe I am being accurate when comparing what we have done to the latest Magnum Motors.
The 318 has WAY MORE parts for it. And cheaper!
That said, selecting the engine is not as important as finding the best USED TRUCK if you are buying used. Either engine will be a GOOD choice. :)

Kowalski I know what you mean. I came off sounding a bit if a jerk...but I guess when Kota Kid said "But it will take several hundred dollars to get a 318 to be as fast as the 4.7 is stock!" it kinda pissed me off a little...
But yeah it's definately true...if you have a V8 Dakota...you're a winner!
When I was looking for a truck, I was just coming off of old classic mopars,(dusters, valiants, darts, demons, etc.) so I really wanted a 360...but chrysler decided not to put it in an extended cab 4x4, so I just forgot about it and looked at whatever V8 Dakota I could find. I test drove about 5 4.7 Daks and all but 1 (probably had the death flash) of them had some good power. In all honesty, when I test drove my dakota, I drove it the same way I drove the 4.7, and I really couldn't tell a difference in power. But I'm sure the 4.7's will pull harder in the upper rpms though, but then again, a simple M1 intake manifold will balance that one one out too, especially if the rev-limiter is raised! haha
As for the cam swap, it's true that if swapping cams, the 4.7 is the obvious winner. But remember that with the 5.2/5.9, you can do a simple rocker arm swap (with 1.7 RRs) and you get more lift and duration without swapping cams! hehe...someday I will hopefully! No time in the near future though!

LOL when I was buying my Dakota in 2003 I was insisting on the 360 (5.9) and they didn't have anymore in the QC from what they were telling me.
So as NovaDak did I simple settled for the V8 they did have which was the 4.7
My bro in law already got his 318 and we were surprised they were neck and neck for the most part. They even sound the same. At least until mine reved past his rev limiter :P
We've had tons of fun with BOTH engines.

Graphite,
I'm sure you could have waited a short while, and ordered, or they would have found a 5.9 for you if that's what you really wanted.
I think you're glad you have the 4.7 though, and having read your posts for years and e-mailed with you also, (the CD shop manual-free), I know you'd love to have the manual tranny like mine.
