You can't go wrong with a V8, just depends on what type of setup you want and how much money your willing to spend. If you want a normal Dodge sport with 15 inch rims no extra's! Get a 4.7L with a 5-speed! You want to stay stock, buy a 4.7L! Why, because it's already tweeked with great parts like the heads,overhead cam, ect.
Now if you want extra's like 17 inch rims, wheel flars, bed covers, auto tranny and great after market parts go with the 5.9L. Why, 5.9L has great torque to move all the extra weight an lots of potental with 5.9L.
Now a 4.7L 5-speed might keep up with a 5.9L R/T, but doing it every day, the 5.9L with the auto will outlast the 5-speed! I don't think you can be friendly to a 5-speed to stay with an R/T. Now put the 4.7L in the R/T package an I now it wont put out 5.9L numbers! It just doesn't have the torque needed to move the extra weight an the automatic tranny. Now put some mods on the 5.9L then you can't compare the too. Or just wait a year or two for the 5.7L, if you want a better stock motor than a 4.7L. Just forget about after market parts for the 5.7L an not to mention that it might come with a heavier or ugly body!

The 4.7 does have overhead cams and it is a very new engine with a bright future. The 5.9 is a engine designed for pulling a trailer. The 5.9 will eat up a lot more gas but will give you more reliable service plus it has a lot more aftermarket availability. But if your looking to race i would get the 4.7 with a 5 speed because it can rev higher and will beat the 5.9 in any package they come and will save you gas money which can be spent on aftermarket parts.

Jesse. The tire and handling package will give you 16" rims and sway bars instead of 15" wheels. I have them on mine and they are nice rims. Also if you get the 4.7 5 speed be sure to get limited slip and 3.92 gears same as an R/T. With this combination you will take down stock R/T's if you hit your shifts right which is sometimes difficult with a truck transmission.
I am not conviced that a 5.9 is more reliable. I think proven is a better term. The OHC and fuel economy and manual transmission is what made me decide to buy the 4.7 sport. Don't have much funds at the momment for mod's so don't really care that less are available. I will make sure I get supercharger by the time the 5.7's come out to keep ahead however. The 5.7's will probably have no mods for a couple years. They are finnaly starting to come out after 2 years for the 4.7.
Good luck.

The newer engines coming out these day's like the 4.7L from Dodge an the GM Straight 6 are already very efficient in power, gas, and smoothness. Simple bolt ON's if any will not make that much of a difference compared to the older style engines like the 3.9, 5.2, 5.9L
5-speed outlasting a Auto, maybe? Depends on how you drive a stick. If you like racing, it's no way it's going to last that long. If the auto brakes it's under warranty, if your 5-speed wears out, it's a wear and tare item. Too bad it's not under warranty.

Have to disagree with Anthony on the bolt on's. The new engines have plenty of room for improvement. They may be better than the older style yes, but by no means cant use some changes. My 4.7 is severly restricted on the air intake. Bolt ons will not feel like you dropped on a supercharger no, but a few combined together will increase your performance. Car manufacturers do not put on the best or most efficient equipment from the factory. They put on what will get them the most sales and save them the most money. For example, instead of a noisy open air intake they put on a restrictive intake that is nice and quiet so as not to annoy any delicate yuppie ears. Cheap brake rotors. Middle of the road spark plugs. The list goes on. Bolt on's just have to be accpeted for what they are. Mild performance ungrades. Just as another example, JBA headers are making more HP gains on the 4.7 than they do on the 5.2, or so I last read. I own a 5.2 and a 4.7. With the few mods I have so far, their is a bigger increase on the 4.7 than on the 5.2 with the same changes. Just my experiences so far.

I just know that the 3.9, 5.2, 5.9L have way more restricted parts than a 4.7L would.
Not much else other than the air intake an plugs need to be changed on the 4.7L.
The 4.7L already has cast aluminum cylinder heads, tuned-length runner intake manifold, free-flowing intake and exhaust ports and fast-burn combustion chambers, 9.3:1 compression ratio, coil-on-plug ignition, variable fuel injection timing, sequential multi-port injection an more.
Only so much Volume can be moved threw a 287CID
Still a very good engine, but if you want more than 235-255hp your going to need a supercharger.
I'm sure compression ratio will need to be lowered, but a good 300hp could be had just like the Charger concept maybe. Then your talking over 1hp per cube.
You can get 300hp easy from a 5.9L, no S/C required. Heads, Cams, ect.

The intake on my 4.7 is just as resrictive from the air box to the throttlebody as my 5.2. I dont have the JBA's yet but they are on my list to get just as soon as I have the cash. I think the 4.7 is capable of more than 255 hp with out a SC. But I could be wrong.

Anthony , what makes you think the 4.7 would not benefit from a set of cams as well as a more free flowing set of heads. Just because the are aluminum does not mean they are made for the strip. NOT SAYING 4.7S ARE THE BEST JUST SAYING THEY ARE FAR FROM HIGH PERF. RIGHT OUT OF THE BOX. For the record the clutch is the only thing not covered in the manual tranny . talked to a service manager at my dealer he said they do alot more autos than they do manuals. thats behind any motor 3.9 and up.

Hey, It's just my thoughts.
Can you even get a cam or better heads? I know you might be able to take your OEM heads and add bigger Valves, port, polish or whatever.
What I guess I'm trying to say is, the avg Joe will have a better chance on modding a 5.9L vs a 4.7L
Also parts for the 5.9L will cost less than the 4.7L.

If you have a ton of money for mod's and have no concern about fuel economy right now the 5.9 is better. For a stock or very mildly modified engine go with the 4.7 IMHO. I do think once internal parts become available if they do this engine could be a killer. The engine size is not a factor at all. The Ferrari is a 3.8 DOHC V8. I know this is a crazy comparison but with the right parts if and when they come out you could easily get 500hp+ out of this motor. The 4.7's overhead cam's are the wild card and as of yet the realistic potential is unknown. The future potential is great. I don't really plan on going that far on my truck just yet so I am happy with the limited number of mod's currently available.

Ok I have to speak up now. The 4.7 was detuned by DC cause they did not want it to over power the R/T (but they didn't do a good job) this motor was intended to produce over 300 hp stock just wait until they release the HO version. I have a 2000 CC 4.7 5 speed 3.55 LSD right out of the box it pulled a 15.2 and beat a R/T CC doing it on the track. The 4.7 is rated at 230 HP stock and the R/T is 250 HP stock but what people don't really know is that the 4.7 puts more HP to the ground than the R/T. Dyno tested the 4.7 will put out over 200 RWHP stock is you have the 5 speed the R/T will only put out 195 or so. My truck as it stands puts out around 270 HP at the crank and about 220 at the rear with minor mods: Chip, Z-tube, Flowmaster, polished TB my 1/4 times now should be in the 14.6-14.7 range. Matt Barret's 4.7 RC 5 speed runs 14.2s with minor mods. I have talked to many companies that are developing stuff for the 4.7 70mm TBs, Cams, Ignition, Intakes, and underdrive pulleys it will all be out soon. It takes time for them to make performance parts. The 5.9 performance was not made overnight it took years but now it is going away. There is a new kid on the block so watch out.

When is this HO version going to come out. Tell me more.
But also i agree the DC had detuned the 4.7 but dont tell me that the 5.9 is giving it all it has. I think DC has to watch it because Ford and GM are almost hitting the 300 Mark with 6 cylinder and there V8s are up there to. It looks better on the TV and it is giving dodge a old look. If the 4.7 was intended for 300 hp now is the time to show it. And dodge should also upgrade all the other engines. The 5.9 is my favorite motor right now but its time to go and go with more efficent engines like GM. I think that chrysler needs to revamp its powertrains and give the consumers all they have to give not detuned.

Dakusa,
You make it sound like the 4.7L is making more power than the 5.9L which is false. Why, the 4.7L loses less power threw a 5-speed vs. the Automatic that is required for the 5.9L. It's not because the engine is more powerful. If you want racing, the auto will give you constant times an the 5.9L will give you lots of room to grow. About the parts for the 4.7L, I'll belive it when I see it. Mopar also makes a bunch of parts for the 5.9L vs the 4.7L. Dealers rather see Mopar parts vs non mopar parts for warrenty issues.
Yes 3.8L is small, but it's a whole different beast. 11:1CR, 8500Redline, Forged Aluminium Pistons, Titanium Conrods, Three intake valves, two exhaust Valves, Four Camshafts, ect.
Just my opionin, each to there own right.

the 4.7 is detuned so as not to compete with the 5.9? Give me a break! Dodge doesn't want to loose those huge R/T sales (maybe 2000 a year) so they will make the most common v-8 in the line suffer? This whould cause Dakota sales to suffer across the board, If the 4.7 could easily make anything more then the 230hp it does now with equal reliability, economy and cost Dodge would be doing it now not tomorrow. Even the 250 (or 245) HP the R/T makes is about as much a Dodge small block has ever made from the factory. I know the 340's were rated at higher numbers but these were rated on a different standard and even the 340 six pac motor would be hard pressed to make 250hp as rated in todays standards. Then of course the R/t makes tons of tourqe very quickly, it's not as good to make RPM when you have to move something as big as a Dakota the average torque from 1000 RPM to 4500 RPM on the 5.9 is a good 330 ft pounds, the 4.7 has a big peak at 3500 rpm but that's only 295, the average in the same range is only about 260 ft lbs. Ths only reason a 4.7 is equal to a R/T's times is if it has the 5-speed. An automatic 4.7 will not run equal to the R/T and the R/T will break the 5 speed over time with it's awesome torque. I have seen stock R/T rear wheel HP dyno's over 200hp as well even with the automatic. I was going to get the 4.7 with the 5 speed but as a compromise with my wife I agreed on an automatic. If I had to get the automatic the R/T was the clear choice, and overall I am much happer with the choice now. The 5speed transimssion may be overall more reliabile as a unit then an automatic if you don't count the clutch, it is almost certain to wear out faster in a racing truck then anything will on the automatic. As far as the motor goes I don't know how you could get any more reliability out of the Dodge small block, and even if something does fail it is dirt cheap to replace, the 4.7 still has to prove itself, how many 200000+ mile 4.7's are there out there? there are plenty of 318's and 360's there.

If you don't like the 5.9L fine wait for the 5.7L!
It's going to be much better than the 4.7L!
According to ai-online, Chrysler will build an all-new 5.7 liter V8 with hemi heads - in short, a 353 Hemi - in late 2001. This engine, which is revolutionary in its retrospective technology, will replace the 5.9 liter V8 (360) at long last.
Dual spark plugs are used to speed fuel combustion, making the engine more powerful and efficient while decreasing emissions (though not down to ULEV levels). A cylinder deactivation system, which does not appear to be related to systems used by Mercedes, prevents fuel from being wasted when the engine is under light loads. AI-Online also noted that the Hemi has double rocker shafts in each head, like its predecessors, but has valve gear within the head walls.
Like the original Hemi, it will produce about one horsepower per cubic inch, if its output is similar to its concept version in the 300C Roadster. To be fair, this level of power is no longer rare.
The 5.7, like its LA predecessors, has a cast iron cylinder block; however, it weighs less and is smaller than the 5.9. It was designed with a single in-block camshaft and only two valves per cylinder, resulting in very low production costs; development and production costs, in fact, are supposed to be less than the new 4.7 liter Mopar V8 which started production last year.
The two-valve-per-cylinder design means not only lower production costs, but also better low-end torque, which is a good selling point considering the high-revving nature of most current generation engines.
The Hemi is designed for trucks, but most likely will be used in 2004 large sedans with rear wheel drive. Currently, two names bandied about are Charger and 300.
The Hemi will be built in Saltillo, Mexico, starting at 300,000 units per year but possibly rising. At this time, engineering is concentrating on emissions reduction. We suspect it will first see the light of day in the next-generation Ram, though maybe not at the truck's introduction.

The 5.9 makes more torque than the 4.7 yes, but the 4.7 makes the same level of torque over a very broad rpm range. The 5.9 has been around a lot longer and has a very proven track record. If my truck had the 5.9 in it I would be just as happy. I love my 4.7 and my 5.2.

I don't know where you all are getting the idea the 4.7 has a flat torque curve. Have you seen the curves published by Dodge? The 4.7's torque looks like a new age Madonna bra, it is the most unflat torque curve of all the Dakota motors. At 1500 rpm it's at 230, it peaks at 3400 rpm at 295, then drops back off to 260 by 5000 rpm. The 360 on the other hand is making 330 at 1500 peaks a mear 15 lbs higher at 345 at 3000 rpm and only drops back to 300 by 5000 rpm. Look at the HP curves as well the 4.7 is only making 140 HP at 3000 rmp, where the 360 is aready making 200 hp. It;s the cubic inches that are making that effortless power at low rpm's on the 360, the 360 can be made to rev with cams, heads, and intake, just look at the 380 hp magnum crate 360. I really like the 4.7 it just needs more cubic inches to be a true bruiser like the 360.

Check out the link, it looks like the new 5.7 hemi will show up on 2003 model rams, but will not reach full capasity until 2004. 2004 will be the earliest that special packages like a R/T ram (or Dakota) will be built with the 5.7 hemi. The 360 will remain in production through the 2003 model year, two year longer then previously reported around this website. So pretty much I only seem to keep a car 3 years topps, so if this new hemi shows up in the Dakota it will be the perfect time for me to switch!

All companys detune their engines for longevity, emmissions and insurance reasons. Their are people that easily get 800+ hp out of the Toyota Supras 3 liter twin turbo setup. If Toyota did this from the factory most would propably never make it 100000 miles they would never meet corprate cafe standards and insurance companys would not insure this car. HorsePower is not as useful as torque here in the U.S.A. . Why in the world would a midsie truck need 300hp? The key to getting more power out of the new engines is going to be in working around or with the OBDII ECM. All of the mods in the world are worthless if they do not adress the OBDII ECM!

My post should have read OBDII not "OBDEII". Under OBDII your ECM must be an Emissions polices as well as self diagnostic. The programing from the factory makes most modification ineffectice and any attempt to do any serious modification with out custom flashing your ECM/PCM will result in tripping trouple codes, and it will normaly force the system into a limp home mode. If it does not trip a fault then chances are it not a worth while modification. With the right equipment flash rom rocks because you can easily reprogram. All of your new vechiles have very narrow operateing parameters.

Well, I'm going for 350+hp 450+tq someday! Here in Mid US their is no smog testing. Unlike the hell hole in Houston. Boy I hated that stuff, every year I did my inspection. Paid my money an got my sticker, yet they had thousands of smoky smelling nasty crap cars and trucks killing the air! I maybe see one or two at most where I live now, an we don't even have inspections here!
I love my 5.9L hog. Their still isn't a replacement for displacement!
Sure 3.0L Supra can make 800hp, But I've seen too many granade them! They need all new stronger parts inside! Huge Twin Turbo's and lots of boost plus some add fuel mapping and other things.
Put that much effort into a 360 and compare the power then.

There is indeed a replacment for displacment. That's why engine are getting smaller and performing better producing more power.
