I was looking around and these are the prototype numbers for the new 5.7L V8.....HMMM this would be nice in a DAK!
A prototype 353 cubic inch (5.7-liter) pushrod V-8 engine featuring hemispherical combustion chambers and two spark plugs per cylinder powers the Dodge Super8 Hemi concept. Its estimated 353 horsepower (263 kW) and 395 lb.-ft. (536 Nm) of torque are delivered to the rear wheels via a four-speed AutoStick® manumatic transmission, allowing the vehicle to reach 60 mph (97 kph) in less than six seconds and clock a top speed of 154 mph (248 kph).
HMMM... What do you guys think??

Off of Dodges North American Auto Show Page. I don't remember the exact address, but theres a link on there main homepage. The numbers are for the Super8 Hemi Prototype but i assume if the engine goes into production that the numbers would be close to the same.

I am just dying to know why do people on this furom keep relating the 4.7 to the new 5.7 hemi,they have nothing in common,and a 4.7 is not a hemi,seen that a couple of times on here.I have read and seen alot on this new engine and that is exactly what it is,"a brand new engine",not related at all to any of Chryslers current engines.Here is a little know secret.when Chrysler was designing this motor they actually got a few pointers from GM and their kickass LS1 engine.The intake manifold,exhaust manifolds,and even the runners in the heads were all designed using LS1 technology.And there is nothing wrong with that,I am a die hard Mopar Guy but you most give credit where credit is due,GM LT1,LS1 and LS6 smallblocks are outstanding engines.Any way I just wanted those to know who have a 4.7 OHC that it is not a baby HEMI,ok.About the 5.7,bad ass motor but with the way Chrysler is going,that motor will be in a new Dakota R/T 5.7,but I bet they will make the truck ugly,and make it more girly,look what they did to the Ram for 2002,and the 2001 Dak dash,GM is doing the same,look at the Pontiac Aztec and the Avalance,whats the world coming to?

More BS from BH, What makes the 4.7L not a HEMI ?? What makes the 5.7L a HEMI ???? lets see if you really know what you're talking about. The 4.7L is as close to a HEMI as you can get, closest thing since '71, OK, they made that little K car in the 80's they called a HEMI.....
Yea, GM gave pointers to Chryslers, ok, this sounds like the same BS that was spread about Mercedes designing the 4.7L.
I totally agree the 4.7L has nothing to do with the 5.7L.

Spark plug location actually has nothing to do with what makes it a HEMI. 4.7L has plugs right down the middle also, basically between the valves, just to the right or the intake valve. Valves oppose each other top and bottom, with a slight skew left to right, rather than side by side. HEMI only refers to cumbustion chamber shape. A TRUE HEMI, has cumbustion chambers that are HEMISPHERICAL "Half a Sphere", or Half of a ball. Most heads are not exactly half a sphere, however starting in 1951 Chrysler designed a cylinder head, which had a cumbustion chamber that was "a ball sliced in half", exactly Hemispherical, thus the HEMI. If you look at the 4.7L head, and compare it to the LA engine you'll see the HEMI design influence, as I've said many times before, the 4.7L head is not a HEMI, to the true sense of the word, however it is very close. if you compare the LA head/4.7L head/ to the Old style HEMI head you'll see what i mean. I have pictures if you're interested. Here's a link to a GREAT picture of a TRUE HEMI head http://www.hothemiheads.com/hotheads1.html
check it out, and compare to other heads....

The 4.7 is not a hemi and wont be close to the 5.7. For one its not a pushrod engine and like mensioned before the spark plugs must be top dead center for it to work. Honda has hemi heads in all there engines but they have dual overhead cams allowing the sparkplugs to go inbetween. The 4.7 has the camshaft right where the plugs should go to make it a hemi.
All heads have a slight rounding but that doesnt make it a hemi. I am not sure but i think a hemi requires 180 deg heads.

You state that your 4.7l pulled more Hp than the 5.9L? Your tranny did, not the engine. Remove your 5-speed and throw on a 45RE then you'll can compare the two engines. Hell just throw on a 5-speed to the old 360 and see how bad it's will hurt your 4.7L.

Even more of a reason to not buy an automatic.
Can't argue the parasitic loss for a 5spd (15% +/-) is less than the auto (20% +/-woulda, coulda, shoulda put a 5spd behind that 360, but guess what, THEY DID"NT! And that was DC's fault, because now you have a situation where another Dakota is available for thousands less ($15,800) that's just as quick, if not quicker than the RT (Stock vs stock).
The RT was supposed to be the "bad boy" truck of Dodge, untouchable, and now look, you can get a 4.7L with 235 hp, and a 5spd to boot. once they get rid of the 360 for good, then you'll see a real RT, one with real HP from the factory!
Maybe Dodge can win some respect back for a real V-8, just like the Chevy and Ford have already done.
I really think you'll see the Dakota RT discontinued, just my opinion, I have no evidence of this, I think Dodge will introduce some type of RT Ram, to compete with the lightning, and it will have the 5.7L Hemi, and HOPEFULLY a Manual trans option, but don't hold your breath. If this happens in 2003, I'll be the first in line, Auto or Manual.

2000dak4.7 put a websight with a magazine article. In it, it said that the 4.7 heads were almost hemispherical BUT NOT A HEMI. So what it sounds like is that all you 4.7 owners that say its a hemi dont even know what you have under the hood. GM and ford owners have nothing but respect for the 5.9 because it doesnt come apart like there engines.
A couple of 4.7 owners her sound like tree huggers.

DC had a few obstacles like emissions and a good 5-speed to handle the 5.9L
I agree that 250hp is not a "bad boy image or untouchable" I wouldn't hold my breathe on the 5.7L dropping into our current Dakota frame. I like the R/T mainly for it's extra goodies it comes with. I drive my R/T daily, a 5-speed can get somewhat tiresome for every day use. I plan on having my R/T for quite some time an getting it into the 13's or low 14's is quite fine with me. But I do hope that Dodge will keep the Dakota R/T with whatever engine that may be, 4.7L HO 270hp or better. I just don't like how everything is almost front wheel drive, 4 cylinders, and maybe even electric.

It already doesn't look good for Dodge! First this 5.7L was thought to have 350hp 400tq. Now it's down to 330hp 350tq (Mopar Mag) That's already 50HP! less than the Ford Lighting! Ok maybe the smaller truck body will make up for the lost hp, hmm needs to be around 500lbs lighter. But with added hp always comes heavier cars and trucks! Another draw back to this new engine will be how hard will it be to modify?

That Hemi requires exactly 1/2 a sphere statment wouldn't hold true for a 426 hemi. If you had say a 4.25" bore of a 426 hemi, which means the circle has about a 5 cm radius. The sphere created would be 523 cc's, 1/2 of which would give a cumbustion chamber volume of over 260 cc's. I can't find a stock hemi's exact cc volume but it's a safe bet to be well under 100 cc's (a low compression 440 has a 83cc head). So Matt you seem to be throwing back some pretty brutal responses about knowing the facts. People who live in glass houses shouldn't throw stones (or clutch plates for that matter).

Great post. I found some latest Hemi news that said the 5.7L V8 would find its first home in a new sedan in 2004 & then would migrate to the Ram. The way they are designing the Ram with 4 doors & all it looks like the Dakota would be the one to get eliminated. Just throwing a wrench to the speculation pool. I gues its hard to argue with a sales rep though.

Have you seen a head from a 4.7 theres a flat side that takes up at least 25% of the combustion chamber. How the hell can that be a hemi. Even the artical that 2000dak4.7 put up said it wasnt a hemi it SAID THAT. So it think that the last time you quoted on "I am not sure but i think a hemi requires 180 deg heads" Just proves that even when im not thinking i still know more then you.
So stop being so damm arrogent and just be happy with the small crammer engine that you got. Even though when you want to show your friend your engine they got to use a microscope.

First the 4.7 liter is awful close to to being a truly hemisperical head. It is not truely a hemi but it is very close. Second their is nothing high tech about the LS1.Third the new hemi from Crysler is not based on the 4.7L. The new hemi has over head valve design with lifters and push rods. The 4.7 liter could be stroked for additonal cubic inches but not enough to allow it to replace the current large small and big blocks and deffinatly not practical for a V-10 set up. I am guessing that DC will have the 3.7 V6, 4.7V8. I have not done the math but I doubt that you could squeze much more then about5.3-5.7 out of the 4.7's block.I think that the new hemi will be used for 360 cubic inchs or more. It will also make an excellent design for a truck v10. These are just guess's.

Look, you all claim to know what a hemi head is but the head is only half of the equation boys. The other half is the top of the piston which actually moves up into the combustion chamber, above the top of the block deck. Hemispherical combustion chamber refers to the fact that piston top is also "half ball shaped" and not flat. I personally have never taken apart a 4.7 but I believe it has flat top pistons. So your arguements about the 4.7 being "hemi-like" could only ever be 50% or less truthful. As far as I am concerned the 4.7 was created to fill in the demand for the 5.2 and 5.9 as they could not build them fast enough and to try and help on fuel mileage accross the entire DC line.
Check your facts and don't sound stupid folks.
Just my $0.02 that equates to $5 of your money.

According to www.car-truck.com they say the 5.7 was supposed to show up in the 2002 ram at introduction but was delayed until late in the year. They also say the 5.7 will end up in the dakota but probably not until the second year of it's redesign, or 2004. They may no do any special versions of the Dakota in 2003 as it will be a complete redesign, and they probably won't have trouble selling a bunch of high priced SLT+ quad cab 4x4's. It's like why bother working on a turbo PT cruiser when they sell every one 6 months in advance just the way it is. So hope the new Dakota is ulgy, then it wont sell, and maybe they'll put together some kind of 5.7 Hemi R/T to boost sales. As far as 2004 goes, that seems soon enough for me, as long as it's not ulgy (some of the drawings look ulgy to me) I think I'll be down for one either used or after they offer at least a $1000 rebate.

In the top fuel cars.... the fuel charge is so dense that it takes both spark plugs to ignite it. Generally, if one of the plugs misfires, it blows the blower right off the car.
On the new 5.7, it's probably more emissions related than power.
