7.3L vs 6.0L

I have owned both motors (see signature). You cannot compare the off the line power and acceleration, the 6.0 kicks butt. I get the same mileage w/ both motors. I liked towing @ 70 w/ the 7.3, it didn't down shift as much. I plan on using a programmer (and exhaust) soon, which will eliminate my tranny complaints. I just love the 6.0, the power, the sound...... did I mention the power, wow the power, I just can't beleive the power, its so much fun to replace tires...... I mean to drive.

By what you posted my peak horsepower should be lower because I have a higher torque number then stock, so my peak horsepower should be lower then it is for stock(if I understand you correctly, please correct me if I'm wrong).
Horsepower is just a measurement, really, but it is a great indicator of how much work an engine can do. The full formula is:
HP = (RPM x ft.lbs.)/5252
So, in a hypothetical example, a motor making 525 ft.lb. at 2000 RPM is making 200 HP. Another motor, if it only made 300 ft.lbs., would have to be turning 3500 RPM to make the same 200 HP.
If you could gear them both to be running at their 200 horsepower peak, they would both be capable of moving the same load at the same speed up the same hill. But it is easy to see which would be the most comfortable and economical, and would last the longest.

The powder coated rods were installed in 2001 the same year of the mechanical diode failure. 400 hp is realisticaly the limit for the powder coated rods.
2000 was the last full year with the forged rods. The 6.0's have powder coated rods. The 6.0 has more hp and tq than the 7.3 but the 7.3 is more reliable hands down.
Even most Cummins and Duramax owners agree that the 7.3 is a great motor and the same can't be said about the 6.0. Some people call them the six point oh no. All the people I know with the 6.0 have had major issues. One guy has two 04's both with a list of repairs longer than most gangsters rap sheats. Another guy I know had a motor replaced on a 05 at 35K miles. Another one with a 04 had the head gaskets fail at 14K miles.

i think youll find mixed opinions with the 6.0 vs. the 7.3
i love my 02' 7.3. my dad has a 04' with the 6.0 and hes had it in the shop a few times. i know a couple people that love there 6.0's. one told me he misses the mileage with his 7.3. its wierd cause it seems some people get great mileage with the 6.0 and some people it sucks.
and i know people who dont like the 6.0. i think its just an opinon issue.
as for me, i wouldnt buy a 6.0l. nor a 6.4. at least not right now.

I have an '04 6.0 and have not had any issues with the engine(which is stock). I have approx 80,000km on it (55-60k miles I believe). Have had no engine issues other than noisy belt, which turns out to be moisture in cool temps and goes away when weather is warmer or truck warms up. I have had the tranny replaced under a recall when it only had 14,000 Km. The truck has been fantastic. When on the highway empty I have gotten a best fuel millage of about 21 mpg (imperial) and mixed driving of about 18.5 to 19.5mpg (imperial). When pulling my 32' fiver I get about 12.5 mpg (imperial). All of these are hand calculated, not of the trip computer. I think the torqueshift tranny is a fantastic tranny and love it for pulling through the Alberta/B.C. Rockies. Never have issues with having enough go power or stoping power. My father inlaw has an '02 7.3 and has also never had any issues, not even the dreaded cps problem which is now an official recall. He does fall a little behind on steep climbs with his trailer which is about the same weight as mine (11,500lbs) but not enough to make an issue of it. As with anny used truck get an Oassis report and if you purchase a 6.0 be very religous on oil and fuel/oil filter changes. This will help in giving you many trouble free miles. Enjoy

Does anyone know the production numbers. I thought Ford was still number one in the diesel market.

The diesel market was Ford's to lose in the early 2000's which they did by having to rush the 6.0 into service because of the EPA. Maybe if they would of had more time things would have been different!!! I remember Gm guys used to think that my 7.3 would blow there early D/A's away when they first came out because of the reputation the 7.3 had eating 6.5's and stock CTD's all day long without breaking a sweat. When the 6.0 first came out it sounded great tons of power, variable geometry turbo, and the like, but then came the roumors of all these problems and the recalls. It was the nail in the coffin of Ford's diesel supremacy! That is a title that will never be won back since GM now has a diesel worth putting fuel in! Now in the 6.0's defense, there are good ones in the 03' and 04' years that have never had a problem. My cousin bought one of the first 03's with the 6.0 in our area, and it has never been back to the dealer! Any 6.0 can be made into a reliable engine by removing the emissions stuff and installing head studs, as well as staying up on oil changes like a hawk.
