My first line was actually a form of irony, i was kidding.... everyone knows that diesels can be fast... My 7.3 off the line is a dog.... but once its above 35-40, very impressive, and yeah your right about the mods, but the damn thing runs so good, i dont want to take any chances with my daily driver with any mods... maybe later down the road!!! By the way, there are heavily modded dodge cummins diesels in the 10's.... fast enough?

 

I dont believe any of the cummins trucks that make all that power are actually the CRD common rail type cummins trucks... i believe they are all like the older 24 and 12 valve engines.. There are from what i know however, quite a few diesel f series pickups in the 11s with a 7.3... i wish the 6.0 wasnt such a questionable motor, it revs a good amount, and when it runs right rides the hell out for a stock truck!

 

yes your right, those cummins diesels are the older ones. but still, diesels in 10's?? that was unheard of up until 5-10 yrs ago......

 

The older 7.3 turbo diesels (stock) are complete dogs next to the 6.0s. I have a 2003 6.0 5 speed automatic 4x4 with 48k miles and it has had no problems to speak of. I also just got a 1995 tahoe 4x4 with a 6.5 turbo diesel.

 

dont forget the advancements that the 6.0's had, the 7.3 was still a pretty basic design.. for longetivity, i would definitely put the 7.3 against the 6.0 its known fact that the 7.3's are just a tougher longer running engine, with little mechanical problems...

 

i dont know if your still looking but i would get a durmax the cummins is a awsome engine but its wrapped with dodge..the powerstroke burns up to easy with upgrade the new 6.0's and there also wrapped with furd and i think duramax and chevy is a great set up my dad and i own 6 of them and there all running strong some in the 500k miles range and no problems all have tuner chips and lifts and tire....

Just my 0.02

 

I change vehicles like underwear and after driving/towing with my Duramax/Allison truck around for the last 4 months I'd have to agree it's the best overall compromise between chassis/drivetrain. I love the Ford chassis but the 6.0 is not so great, and the new 6.4 dosent look much better..

 

I think i have a comparison for you guys.... check out the domestic companies making the most money in the open markets these days. It IS DC and Cummins. I like all the trucks for different reasons, and i have seen quite a few HIGH powered trucks that are modified all to hell. However, the most industrial based setup, and the only one that is used for medium duty, as well as has the longest service life, is the cummins. It gets a 50k mile longer rating, and makes nearly the most power WITHOUT .7 liters on the Duramax, AND it is lacking all the aid of the gadgetry on the 6.0 and LLY/LBZ d-max. No VG turbo, and it doesnt have the HEUI/cat( i think) style injectors that international uses in the powerstroke, which in the 6.0 worked so well they melted a piston and popped a hole in another piston I guess when i hop on dodge websites and see 1/2 as many people bitch about nearly as much crap, i will venture elsewhere... for now, im getting rid of my f-250 for a dodge!
