Not trying to start a battle here, just looking for a reality check. This weekend I went to look and test drive a 2001 7.3 2500 crew cab long bed 4x4 6 speed with a friend who is interestd in buying it. Driving the Ford compared to driving my 05 quad cab long bed 4x4 Dodge was very dissapointing. The ford had some aftermarket stuff like cold air intake and 4" exhaust, and supposedly a chip, but I can't verify that. It made a bunch of noise and I could hear the turbo spool up but there sure wasn't any pushing you into the back of the seat feel. My cummins lags until 1600 rpm and then the turbo lights and your off. Is there really that much difference in the 4 years between 01 - 05 or should the 7.3 be more like my cummins in feel? I know theres tire size and ratio's that play a part here, but there was a huge difference. At this point I can't suggest to my friend that its a good buy, but maybe if I drove an 01 ram it would be the same feel as the 01 ford????

any stock tuned 7.3 will not feel like your dodge
but a custom tuned 7.3 will roll down the road & hold its own but not a can hand held tuner but a PHP tuner , DP tuner , swamp tuner or any other coustom tuner is the only way to go
& a 05 dodge cummins is a common rail & has i think around 70 hp more than a 7.3 powerstroke
but a tuned cummins will out do a tuned ford 7.3
hope this helps
 
the 7.3 was/is never a beast.
their allure is in their reliability, mainly because they arent turned up and dont have enough power to break...

Now a 7.3 can be made to scream, but like for like a 6.0/6.4/6.7/or any of the CTDs and most of the Duramax's will outpull a 7.3
 
My 02...which BrownsXJ has now was a total turd in stock form. These trucks were built to be a workhorse. Even the stock Superchips which it came with and then the TS chip I got left a lot to be desired. BHAF, Wicked Wheel, 4" MBRP with no muffler and some tunes from PHP and it would roll. Not as fast as my friends dodge's and chevy's, but it would hold its own. You want a race truck or a tow rig? Want both, Get an LBZ Duramax and throw EFI Live or PPE on it.
 
I've noticed it too. Even the first gen Cummins in my K30 feels way stronger (and is :D ) than the DP Tuned 7.3 in my supervisor's F350 SRW. Comparable trucks as well, both are reg cab, long bed, 4x4, srw. Don't get me wrong, his does just fine...I guess I just prefer a Cummins.
 
Determine its power under load. Throw 15k behind it and see how it pulls.


This.
Hopefully this isn't taken as adding fuel to the fire, but pulling to Windrock last month with ~7k, I witnessed an '07 cummins get left by my powerstroke, another '00 F250, a Duramax & finally a 1/2 ton Chevy gasser.
 
Just like most people said a 7.3 is never gonna touch a common rail cummins i dont care how built it is. Even if it does keep up with it, the 7.3 will never touch the cummins reliability. 2 extra cylinders, hpop, electronic injectors, weak connecting rods, the list goes on. I will say im very brand loyal when it comes to a cummins, but its because ive owned countless cummins and ALL have been awesome vehicles. Ive also been doing the diesel thing long before anyone knew what a 12v with a fuel plate was, ive been around and worked on every diesel and ill stick with the most reliable, and the easiest and cheapest to work on. Want proof go look under the hood of 20 random road tractors (sorry big trucks, im a truck driver), tell me how many are v8's, none, its just not a practical choice. Even the so called "big brother" of the 7.3 is a deserter, its an I6 like the rest not a v8!

I know this will piss off v8 diesel owners (well powerjoke owners, cause the duramax is actually a decent v8 diesel) but i really dont care, be mad and come back all you want, you cant argue with pure facts.

I know of an 07 cummins right now that the owner will hook to his heavy gooseneck and take on any 7.3 unloaded and walk off from it, and its on 37's with nothing but a smarty sr and sb dual disc. Ive seen it flat murder a 2wd 7.3 with a box and he had the gosseneck hooked to the cummins at the time. I'll be glad to put my 1st gen cummins on 37's against a 7.3 even with the little mods i have cause ive rode in and drove many 7.3's and know what they will do, they do not impress me at all.

so you are saying that a diesel V engine is "not a practical choice "
then why does so many companies use a cat 3412 V engine in there backup generator & it has hpop, electronic injectors
or what about the old relable cat 3408 it is a V8 they are in cab over road trucks
awww.hankstruckpictures.com_pix_trucks_bc_trucks_langley_mclellan_cat_3408c.jpg
also how do you get that the 7.3 has weak connecting rods they are Forged all the way up until late 01
& lets hear about " the list goes on "

not trying to make you mad but just listing the facts
& no i am not mad :D

7k doesn't count as towing.
 
I'm guessing you are having trouble reading because I thought the topic was on v8 diesels that are in vehicles, I may be wrong but that was what I was reading. Either way so when is the last time you saw a 3408 put in a new truck? The early 90's that's when. They also weren't only in a cab over, I drove a l9000 tri axle dump for many years with one in it. I'm guessing you have never drive one either cause you would know they suck on power compared to a comparable 6. Point being the v8 diesel in a road tractor has gone the way of the dinosaur because they aren't practical. By the way I'm by no means brand loyal when it comes to an engine in a road tractor, but I've drove many different ones and know what I think works better.

Now for the weak connecting rods, I thought we were speaking on the 01 and up powerstroke and that's what I'm quoting on. So if I've misread on the year I'm sorry, if not I made my point.
 
An inline motor will be more durable that a V configuration if it is forced to fit in a comparable space. The bearings are smaller on a V motor. Its really that simple. By putting the pistons side by side, you leave space between the rods for bearing surface. With a V motor, you are trying to fit twice the amount of rods/bearings in the same space. Thats also why you can get more power from a V motor with a smaller package. But once you introduce turbos, everything changes, and compression and boost pressure come into play, bringing durability back into the ballgame (more boost=more pressure=more stress=need for more bearings).

i am not having trouble reading you just forgot what you said
you started with the "Want proof go look under the hood of 20 random road tractors (sorry big trucks, im a truck driver), tell me how many are v8's, none, its just not a practical choice. Even the so called "big brother" of the 7.3 is a deserter, its an I6 like the rest not a v8!"

i was just saying there are some & they are still alot out there with alot of miles & i never said they were only in a cab over
so if you drove one with a 3408 for years why did you say "tell me how many are v8's, none " ??:confused:

sorry for making you mad
 
Comparing a 7.3 to an 05 common rail is like comparing apples to oranges. It's just not even the same.

With that said I love fords, especially the new 6.7s but I can't afford one. I plan to buy a truck next year and I'm pretty much stuck buying a dodge so I can have a reliable truck. I think fords look better, ride better, and sound better but I can't argue with the facts. I need a truck to tow and I want it to last me 10+ years and have a manual transmission while getting acceptable mileage so that makes me stuck with an ugly horrible sounding dodge. Oh well. Lol
 
I'm agree with Shawn, my trailer weighs 6,400 pounds empty. I'll easily max out my 26k tag and not have any issues keeping the speed limit with my cummins. Sure I've had guys pass me with their powerstrokes or duramax rigs and I've passed them too. I'm not usually in a hurry when I'm pulling heavy and I'm certainly not going to be hot rodding around the highway driving reckless just to prove a point. I'm betting on my bone stock 325 HP 610 ft-lbs cummins draggin my stuff anywhere I need to drag it, doing it in comfort, and for several hundred thousand miles. Sure I could juice it and spend thousands on it to push the limit, but then I would probably have more noise to deal with, more things to maintain / inspect all the time, have to constantly monitor tempts and such because face it, we all start adding crazy power to the engine and think I'll just take it easy on the trans until I can afford to build that too, and then its the egts are getting out of hand, and the pinion gets sloppy quick, etc... And help the poor guy who borrows said truck and gets a dissertation on what he has to do with the programmer and what to watch, and what to do if this gauge reads over this... yada yada yada. I'll throw my money at the toys I'm dragging around on the gooseneck and let my tow rig be a get in and drive reliable truck. Don't get me wrong I monitor my temps and pressures and have the gauges and all too, but when its said and done, I need at least one stock truck that does everything well, not just one or two things.

The reason I started this thread was because I've heard such great things about the 7.3 and was very dissapointed with the power of this supposedly chipped, exhaust, and intake modified 7.3 as compared to my stock cummins that I couldn't tell my buddy it was a good buy because I thought something must be wrong with it. Turns out according to the postings here, what I experienced was normal... And yes I know that the new powerstrokes in stock form have more power than my 05 cummins, and next year the duramax will out do the other two, then the cummins will be on top again and so on. Good for them that way the consumer wins, it would be boring if everyone ran a cummins since competition keeps the engine manufacturer's turning screws. Just us cummins guys only need 6 cylinders to keep up with the other guys 8...
 
There is alot e-penis in this thread. :eek:

Fords sound like stopped up vacuum cleaners. Dodges sound like trucks. Maybe your problem is that you've been spending too much time doing housework.
 
So it sounds like i want a common rail cummins with a new allison in ford chassis???? Wait that is what i want in the Excurison......

yes i have a 2013 f650 with a common rail cummins with a new allison in ford chassis
it my DD company truck
 
This thread sucks.

sorry for making you mad
Never said I was mad just trying to make sure my words and info are on point and not turned around so I can have a competent argument. I just don't need a lesson in big trucks, your talking to someone who has logged damn near 800,000 miles in many different trucks and motor and trans combinations. Has nothing to do with penis size, since we're are all white I'm sure no one has anything to brag about. Just trying to keep this from turning into a Obama/Biden debate where everything gets so off debate we have no clue what the heck anyone's talking about.

Like I always tell those proud powerjoke owners, we all make big mistakes in life, it's whether we learn from them or not. I just got lucky enough to learn before I made that mistake.
