That depends on which one you are talking about. The 6.9 had 310 lbs of torque at 1,600 rpm and 175 hp. That would put it on par with my stock 5.0 truck that makes 185 hp and 270 tq. The difference is, the 6.9 will do at 1,600 rpm what my 5.0 has to turn 4k rpm to do. The 7.3 had 185 hp and 360 tq, which would put it on par with a 5.8 that had 210 hp and 325 tq. It actually more low end torque and would do a better job cruising at 60 mph than the current 5.4. The 5.4 would run off and leave it once you downshifted though. Not exactly what I would call "boat anchorish", but not going to win many shoot outs.

Every time we came to a hill, the N/A Ford diesel was lagging behind, waaay behind. Can you imagine being slower uphill than an S10 Blazer with a 2.8 V6? I knew then and there I would never own a N/A diesel. I just don't see the point in it, I mean gas ain't THAT expensive!!
I have a 26' camper and I pulled it with my 5.0 a couple of times just to try it out. Going up this one hill I started out at 45 mph and before I got to the top(less than 1/8th mile) I was in 1st gear doing 15 mph with it wide open. I would expect about the same from a 6.9 since they have the about the same hp and tq. My 5.4 and 7.3 don't even know there is a hill there.

Sounds like you have a lot more experience than I do with N/A diesels, so I'll have to take your word for it. But another thing I remember is one trip back from the dunes around '89 or so. I had my S10 Blazer with the 2.8 V6, my Dad had his Dodge (what else would my Dad drive?) van with a 360 and our freind had a near-new Ford truck with an unblown diesel. Dad and our freind were pulling 24 ft trailers of near equal loads, while I had a trailer with mine and my wife's quads and some tent-campling stuff.

I have never driven an old blazer with the 2.8 in it, but I can't imagine anything being slower than my 2.9 Bronco II. They claim that is had 140 hp, but it struggled to even maintain 35 mph going up I-77 and got 10 mpg's in the process. It was about a 480 mile trip and I would have to fill up 3 times.

The 2.9s were held back by gearing in many Ranger's......a Ranger with a 2.9 and 3.45s were slugs, my carbed 2.8 Rangers with 3.73s and 4.10s were much quicker..........We were in a friends 85 2.8 Blazer, we were passed by a Pinto station wagon going up a 7% grade at 5,000ft!.........and he was floored in 2nd at 35-40 mph!

Crazy001, I have taken physics, done research, and know what I am talking about. Here is a basic article that is one of many sources that back up my statements. HowStuffWorks "For towing, what's more important, horsepower or torque?" Fishin76 & Mountaineer your arguments are right on.

Wow.
I don't even know what to say after that mental image.
Is there a pic?

Of a V10? I know sevral stock pulls, one super charged driving on the street and one very modded V10 pulling, not sure what was done.
I can link them tonight if you want.

I know we have some pics of it somewhere, but I will have to find one and scan it. My scanner is at work, so it will be at least Monday before I can get it posted.

I saw all of them, I was looking for A turbo'd or supercharged truck on the track or hooked up to the sled. if you any of those that would be sweet if you linked them.

IThat is a test the v10 will win every time. In the real world (or a shoot out from a dead stop) you have to use ALL rpm's and not just peak hp. If you took the hp ratings of each engine every 100 rpm's and averaged them, your PSD would have a higher average hp than the v10 even though it has less peak hp. The v10 you raced was a tuned 2v, so a little less hp than a 3v, but from a dead stop you beat it by 20 mph and you had to let off the gas because you were going too fast.

...you might want to re-read it. Tom did a power-brake launch (to bring up the turbo pressure) in 4x4. I didn't nothing but step on the gas in 4x2. In fact I slightly feathered the throttle initially to keep from breaking the rear tires loose (and I was worried about shooting Tom's MIL's SUV out the back of his trailer). If I had done a similar launch or Tom had done one similar to mine the results would have been different I am sure.
Also keep in mind Tom's truck has 5 speeds (Torqshift) and I only have 4 speeds (4R100).
I'll give you tuned since I was running a 5 Star 93 tow tune and headers but it's not in the same territory as the 3V. The tune was really the only "advantage" I had, other then being about 1400 lbs lighter, over Tom's truck. I would say it my truck did well for being 8 year old technology.

A shorter first gear would have allowed his V10 to climb up in the RPM range much faster so it would have held higher HP levels through the entire pull.
I really wish we had a stock 7.3 to compare Mike's V10 with. I'm guessing 7.3 with the same transmission wouldn't have come close to the V10 for speed at the top of the hill. The torque ratings of the two engines are close enough that I don't think either of them would hold 3rd gear, but the V10 would be able to rev much higher in 2nd gear and carry a higher speed with it.
And Mike, Matt(i eat hybrids) is trying to put together another one down in the General Diesel Discussion forum, you might want to take a look!
