I FIGURE THAT THE BEST PERFORMANCE COMBO FOR A NEW DAKOTA WILL BE THE LIGHTEST TRUCK WITH THE MOST POSSIBLE GEAR AND POWER. STANDS TO REASON THAT THE R/T PACKAGE WITH NO AIR CONDITIONIG AND THE FEWEST POSSIBLE OPTIONS WILL GIVE THE BEST POWER-TO-WEIGHT RATIO. BUT---THE ONE THING THAT EVERYBODY FAILS TO TAKE INTO ACCOUNT IS THE TOTAL GEAR MULTIPLICATION. EVERYBODY THINKS THAT THE 5-SPEED IS THE QUICKEST TRUCK, BUT, THAT IS ONLY TRUE IF THE FIRST GEAR IN THE MANUAL TRANNY IS LOWER THAN THE FIRST GEAR IN THE AUTO TRANNY. I KNOW FOR A FACT THAT A AUTO Z28 IS QUICKER IN THE QUARTER MILE THAN A 6-SPEED BECAUSE THE AUTO HAS A 3.09 FIRST GEAR AND THE 6-SPEED HAS ONLY A 2.66 FIRST GEAR. SO---DOES ANYBODY KNOW THE FIRST GEAR RATIOS IN THE MOPAR TRANNYS? I AM GOING TO ORDER A NEW DAKOTA AND RIGHT NOW I AM TENDING TO BELIEVE THAT THE AUTO 5.9 R/T WILL BE QUICKER THAN THE MANUAL 4.7 SPORT UNLESS SOMEONE OUT THERE CAN INFORM ME DIFFERENTLY ABOUT THE TRANNY GEARS. PLUS, I AM FAIRLY SURE THAT THE AUTO WILL BE EASIER TO GET OUT OF THE HOLE. ANY INFORMATION WILL BE GREATLY APPRECIATED.

Don't know where you live but I would be "quick" to get out without A/C. Why don't you get the A/C and short belt it for track driving? BTW, here is the info I have: The 5 speed is the NV3500, don't know what the automatic nomenclature is.

Gearing has a lot to do with acceleration and top speed...but where the TQ and HP power comes in at (and where it peaks and holds) is also a consideration. Don't forget the differential gearing as well if you're going to use the gear-multiplication.
Haven't forgotten about it...but the variable for the high HP engines (400+) would require different gearing again since the TQ and HP is much higher and can move the vehicle easier and at a higher speed with taller gearing. (Exceptions...they're always with us.)

Well, having had an R/T, I say screw the 4.7 and go for the 360. You just cannot beat the torque and the fact that there are go fast parts for the 5.9. There is no replacement for displacement especially once you get the bug to make your Dak faster. The 5.9 is the long term choice for performance and upgrades. You can also get forged pistons and cranks to withstand some serious supercharger blow. The 4.7 is great for economy but since you are mentioning saving weight by not getting air, you seem like you want a majorly fast truck. Go 5.9 hands down. The auto works good and the 5 speeds are so slow to shift that they slow you down.
Just my $1.00 worth since I have now owned 2 5.9 dak's.

Lookiing forward to demolishing those 5.9's fairly soon with my 4.7 sport. The OHC will allow for very high rpms and great sprinting power down the track. I will let you know what I think once I get my truck. I test drove the R/T so will be able to make a comparision. The parts for the 4.7 are allready starting to come out so I am not worried about that.

I have a 5.9 and dont think it would beat a 4.7 dakota. The 5.9 weighs a lot more and it takes longer to rev up. I think its more reliable but it just doesnt want to build up speed past 75mph it still climes to about 120 but it takes for ever the 4.7 i find has a much stronger top end. Plus you lose HP when you buy a automatic. Plus if your racing unless you have a modified auto the manual will stand up better. And i think instead of talking about the gear ratios and stuff like that we should just look at the dodge tow rating were the 5 speed can tow up to 50 Lb more then the auto. I think that says it all. To end this story if you buy a auto 5.9 and someone comes beside you at a light in a 5 speed with 4.7 that knows how to shift you will be sorry.
Also can everyone stop talking about there 4.7 engines like there from the cart racing series. They red line just a little over the 5.9.

if you want to go fast just buy the low budget kota and throw in a 528 hemi (it WILL fit) backed by a lenco 5 speed, with a carbon fiber drive shaft (it weight only 7lbs) ditch the leaf springs and get a 4-link with coilovers and a narrowed ford 9" rearend with some 4.56 gears. It will go pretty good. good luck

I agree with Kota...sounds a little expensive, but thats what credit cards are for!!! But hey if you want actual drag strip racing, you can't beat an automatic for consistancy. If your a street racer, a manual trans is better for stoplight duels.

In reference to an above statement that a manual trans can tow more (if the 50 lbs in the post was accurate that is probably only do to the weight difference between the transmissions....not the trans ability....the truck can only tow itself and so much weight). Towing with either has problem potential......clutch burning (manual)/ overheating (auto).
This is alot like the Ford Mustang 5.0 vs 4.6......lots of parts for the old and not much for the new. But as stock engines they were neck in neck in power and 1/4 times. They just made their power differently... the 4.6 made it at higher rpm's and that made 5.0 folks think less of it. 5.9 vs 4.7 is apples vs oranges....they are both great, just different.

I bought a truck with a 5.9 to use it for towing a heavy boat. All I see is the 4.7 owners talking about blowing away the 5.9 after they get this mod or that mod on. If they want to compare them, they need to compare the same mods. Cat-back's on both. K&N on both. TB on both. Not boost up the 4.7 to run against a stock 5.9.

Sorry Brian crisman but I have to disagree. I think the diffrence in the towing is that there is one more gear but the high gear is the same as the autos high gear which means that gear 1 is lower or that there are more closly spaced. You can make more rw hp with manual thats proven. Plus the weight of two trannies makes no diffrence because the weight of the driver or passenger can easily beat the diffrence.

Nowadays, the efficiencies of automatics are pretty close. There is only 1-2% difference between the two. If one opted for a custom valve body on the auto and a custom torque converter there is no manual shifter, human or otherwise, out there that's going to beat that auto and that custom TC's torque factor will kick butt! ;-)

No, there are not. This one will be hard to mod, I believe. A lot of things are controlled by the TCM so the mods will probably be to that. I'm told the programs in the TCM are much more complex than the PCM so I'll bet it's going ot be a while.
