I have read up on a LOT of lititure on the 6.0 and the motor is not that much more impressive than the Duramax Reasons:1 i found a graph showing all torque is up high.for a diesel it cant be good to have the #$%@ wound out of it just to keep a 8,000 pund trailer moving. 2 it is rated 100 pounds less than the current Powerstroke(7.3) and it is too small for a V8 to be competitive with other diesels.I am not BASHING or tring to offend. I just want to hear your opions on the 6.0 with a 2,000RPM torque peak and only 6 litres?I love the 7.3 and hate to see it leave.Now I would be considering a V10 and has a lot of power and a relatively flat torque curve and with a few mods will be conpetive in outpulling a duramax up a mountain.
Thanks,
Dusty
PS I will ask Ford why they derated the tow ratings and made the torque curve so high(for a diesel)and low end almost non existent!
The new engine produces quite a bit of low end torque. I don't know where you got your information, but it is wrong. The peak torque is at 2000 rpm's, but around 1600 rpm's it produces just as much torque as the current 7.3. The torque curve develops and maintains torque over a much broader curve than the 7.3.
As for the decreased towing capacity, it doesn't have to do with the engine, but the GCWR and GVWR. The new engine, from what I've heard, actually weighs more than the current 7.3 because of the design. That's the reason for the decreased towing capacity, not engine performance. This is also not a new engine, it has been used in other applications for something like 2 years now.
I think the new engine will be great. However, I just bought one of the last 7.3's.
I just felt like I prefered this engine, for its record. It can produce huge numbers and has been around for awhile now. I did not want to be a beta tester for ford. I figure after about 3 years if the new engine is showing good records then I may trade up for one.
My biggest concern with the new drivetrain would be the transmission. I think it is allnew and unproven. I hope it does great, but I just did not want to be testing it out for them.
Advertised horse power is 325 @ 3300 RPM and peak torque is 550 @ 2000 RPM. These engines have about 8 hours of green growth in them and once they are broken in they will typically run at about 340 H/P and 570 ft.lb. of torque with stock fuel maping.
I would advise anybody who is uncertain about the performance capabilities of this new engine to wait until there is one available for you to drive before making your decision. I really think you're going to like this new engine.

From what I've read and heard, the 6L is supposed to produce at least the same amount of low-end power as the 7.3L.
I'm not exactly sure why Navistar decided to use a smaller CID, however, the 6L is outperforming the Duramax is every way, and is pretty much better than the HO cummins.
I also read that 4:10 gears are available in every application, so that will also help some in low-end power.
The new 6.0 is also supposed to do 0-60 in 9 seconds. If you're looking for power and speed, this engine is it. The new 6.0 flat out beats the Cummins and Duramax.
[updated:LAST EDITED ON 10-Nov-02 AT 09:42 PM (EST)]Let me tell you that this engine is going to be great. I drove one about 3 weeks ago and was very impressed. It is very quiet and has tons of get up and go. We drove this and the 2003 duramax through the same courses and what a difference. The new diesel is just as quite as the duramax as well. One of the gentlemen that was with us was telling us the did a drag race between the truck that we were driving (Crew Cab dually 4x4) and a 4.6 litre mustang and the mustang won by 3 car lengths in the 1/4 mile. I think it was the 1.4 mile but not absolutely positive. They also did a test that we watched with a 3/4 ton super cab long box duramax 4x4 and the same crew cab dually 4x4 and towing 8000#'s the 6.0L power stroke won by about 2 truck and trailer lenghts in the 1/4 mile. I have no doubts that everyone that drives this will be more then impressed. This engine rocks.
FYI. The truck is rated at 550 lbs ft with the 6 speed and 560 lbs ft with the 5 speed auto.
It also offers 18% better mileage which will be great as well.
Dustin R -- I don't know if I would consider 2000 rpm "wound out of it". At freeway speeds with my current 7.3L and 4.10 rear I am hitting 2200 at about 65 mph to 70 mph. According to my latest dyno, my peak torque is actually 2200 rpm, but it pulls like a monster even below that...
[updated:LAST EDITED ON 12-Nov-02 AT 00:51 AM (EST)]Each production engine is a little different. That is also true of ECM's -- they may not all be flashed exactly the same and even if they were your engine may respond slightly different to the same ECM than the next engine. The torque curve is fairly flat from about 1300 or 1400 RPM to about 2200 or 2300 RPM. I've seen engines that peaked at 1600 and others that peaked at 2200. According to the 99 update manual, torque is at about 490 ft.lb. at 1500, 495 @ 1750, 500 @ 2000 and 495 @ 2250 -- I'd call that a flat torque curve.
The point is, the new 6.0L is in the same ball park. Torque peaks at the same RPM as the old Power stroke and horse power peaks at the same RPM as the old 6.9L/7.3L IDI engine, 3300 RPM and the earlier Power Strokes H/P peaked at 3000 RPM -- the change is not that great.

I was baseing that on the information I recieved from the factory. Theres obviously a mistake somewhere but I will let you know.

The information has just changed so many times. The 560 lb ft for both auto and manual is the most current information from the Ford website. The 7.3 had different ratings for the auto and manual, but the 6.0 will indeed be the same, 560. 550 was the old number that was put out there before they upped the torque.
