99 with 3.9, I personally like the style of them better not to mention the 3.9L is a better motor, not quicker but more reliable.
Look at it as this 3.9L = 318 - 2cyl
The 318 is one of the best engines chrysler has.

I just traded my 2003 SXT with a manual 3.9L V6 for a 2004 SXT with a manual 3.7L V6. Before I test drove the '04, I hadn't noticed the change in engines on the window sticker, but when I drove it I knew something was up. Dodge did a nice job with the 3.7. Being old school and believing bigger is better... Now I think maybe that isn't always the way to go. In this case I'm definitly happy with the smaller engine. It has more power (you can feel the difference when driving) and gets better gas mileage.

I would definately consider the 3.7L. I love mine. I've had two 3.9L Dakotas and I think the 3.7L is a very good improvement. It has really good power and pulls very nicely.

Come on, the 3.9 only pulls 175HP while the 3.7 is like 210.
whats to argue? Smaller engine, more HP, better mileage.....wish i had a 3.7!

something you all have to take into consideration with the 3.7 vs the 3.9 in power aspects is that the 3.9 were made well and reliable. the new 3.7 has more performance items on it than our older motors. so while the 3.7 comes with 210 hp from the factory and teh 3.9 had 170, it will be much easier to bump the 3.9 up to about 250 hp than it would be to do the 3.7 to the same numbers. there are just many improvement to do to these new motors that the OEMs have not already done.

good and bad things about what you said steve. sure you can upgrade the 3.9 more but the good thing about the 3.7 is you dont need to. you wanna ad power, supercharge it, goes both ways, why waste your time trying to add miniscule power by rocker ratios, no point in throwing money away.

so again what are the improvements i can make on the 3.9L to make 250 hp that would be a substatial gain. i was thinkin of edlebrooke headers and a jet chip for it but that would only put me at about 200-210.what else can i do???

ok don, this is what i have in mind for my 3.9. some kind of cowl induction, v6 performance tb, tb spacer, perf. intake manifold, perf. cam, lifters, pushrods, roller rockers, vavles, valve springs, port and polish my heads with a 3 angle valve job, pistons and rods, msd 6-offroad box, 45k volt coil, headers and exhaust, underdrive pulleys, remove a/c, injectors, and maybe a chip, module or a vemon 400 module. i figure that will put me up there in power.
if you want more info on this, most of it is available thru hughes engines or krc performance. Steve

Yeh you can get up to 300 + hp out of the 3.9's, but your looking at spending $7000... That's if you replace all sensors, and put high quality non performance parts in there to back up the actual performance one's...
The 3.7 is a more modern motor as in over head cams and so forth... Can be modded on up into 300 hp with bolt on's...
But the 3.9 can be worked on very easily and when taken care of can last up to 300,000 miles or so...
But I think I would still rather have the 3.7's simply because they start out with more power = not as much will have to be done to them to get some real power out of them...

well, i dont have one on my truck yet, but my brother has one on his 97 neon ACR, that is definately worth it. he has 127k on his DOHC and it is strong with it off, but when he turns it on, it is nuts. i also like it how it only turns on when you smash the gas, saving some change at the pump.
i just put an electric fan on my truck last week, that is a good mod it gave more power and it stopped my belt squeal. plus, now my truck stays really cool even with the fan off. by the way, i have a single 16 inch derale cooling fan with adjustable control and i cut off switch i ran to my cab. good luck, Steve

ok greg, i just added up everything i wrote down and for it all it is 3700. if you take out the high compresion pistons, h beam rods and headers, it is only 2500. that is not very much at all. most of it is from hughes engines. Steve

I was referring to major engine work such as stroking, head work, cam, rockers, lifters, intakes, injectors, intake, tb, ignition, touch up work for looks "valve covers", all new sensors, exhaust, roller timing chain, and so on...
Now if you start adding up all of that up you will find out that it gets very exspensive... I know because I put a little over 6 grand into mine and most of that was just the necessity stuff to go along with the horse power stuff...
