duramax diesels

[HGM]

Basicly, what John said.

The 7.3L is a tried and true tank. When it was designed , it had marine aplications that were tuned for 600hp and 1000lb ft of tq. You most likely wont be able to blow one up with whatever modifications you add. It has approx 265hp in stock form, depending on the year.

The 6.0L was designed to meet upcoming emissions and deliver performance that the customers were looking for. There is a growing "Hot Rod Diesel" market. It is a higher reving(4000rpm vs 3200rpm), 4valve configuration with a variable turbo. In stock form, I belive the number are around 325hp and 500lb tq. It is built closer to its limits than the 7.3L. Both the 6.0 and the Duramax have had injector issues early on and head gasket issues when modified. If you leave them stock, they will hold thier own with most modified 7.3's. If you tow, you will be very impressed with the combination of the 6.0 with the Torqueshift trans. They really run good.

Just making sure you compare apples to apples. I dont think you'll go wrong with any of them as long as you take care of them.

The last couple of years, the Cummins has been quieted down; it is no noisier than the Duramax or Power Stroke. That is one nice thing about the intro of the Duramax; Ford and Dodge had to respond competitively to how quiet the Duramax is. My '01 Cummins, is loud. It is stock and you can not hear the exhaust over the noise of the engine itself...

All of the Big-3 had mediocre autos behind the diesels until recently. They were upgraded versions of gas engine autos. Funny to think about, since in the Dodge case, the 727 auto held up to 426 Hemi's and 440 six-packs, but just didn't like the grunt of the diesel... In the case of the Ford, the C6 held up to BOSS-429's and such too, but didn't like the diesel...

Dodge upgraded a couple years ago, although it's still a 4spd auto.
