Well despite my protests, my parents purchased a 2005 6.0L powerjoke F250 superduty with a 3.73 gear. Im used to driving both the 12valve cummins with a 3.5 gear and the chevy 6.5LTD with a 4.10....

I must say im impressed with the Found On Road Dead, from 2000rpm on up its WAAAAAAY ballsier than either the dodge or chevy. Under 2000 it's all chevy.

Now we are keeping the chevy for a while. *whew* But should I be expecting performance out of the chevy after a 4" straight exhuast, opened up intake plenum, loose air filter, and 15psi MAP/Baro hack to match that of this stock powerjoke? Im thinking no, but the gear ratios are a good bit off so that could make up a big difference...

f-250 superdutys are nice trucks but if i was gonna spend that much money i woulda deifntely went with the dmax

Hm, I would want a sturdy truck with solid axles front and rear with sufficient ground clearing and a purely mechnical engine and eventually a manual tranny.

What would I have to buy to get that?

That 6.0L should put out a 1000 ft lb with tweaks. a 6.5L can't even dream that big.

Here we go again. Why compare a Ford 6.0 to a Chevy 6.5? That is like comparing a cruise ship to a lifeboat. I owned a 1996 F-250 Powerstroke and it was 10 times the diesel the 6.5 will ever be. But then again, even used they cost twice as much, and buying parts for those things will make you go broke in a hurry.

a mid 90's dodge 12 valve cummins with a stick would fit your criteria. plenty of ground clearance, straight axle in the front.

my grandpa has a "95 powerstroke, and yeah they sound powerful and will lay you back in the seat unloaded, but other than it being a dually, in my opinion my 6.5 will hang around with it in the towing. and hes had a lot more trouble out of it than we have the 6.5 other than our crappy fuel system

The one issue with the chevy was first, the LB7 (is that the latest motor out or the LLY?) is having serious injector issues as well is economy issues, all of chevy's current gassers consume oil faster than my 265,000+ mile toyota does, and the cummins 600 was having serious issues with economy as well.... Secondarily NO chevy dealer we went to would deal....Ford however did, so we got it.

The turbo whine from the 6.0L is damn near deafening, and easily overpowers the sound from the diesel engine. Turbo whine is cool however! :D:D You can even hear it spool down. It's still a Fuggin Old Rebuilt Dodge though :( lol

Right now I think the Ford will do 0-60 in about 8 to 9 seconds, I was wondering is there any way I can make the 6.5L do that with the mods I listed. Obviously after some tweaks to the 6.0L there is no hope for the 6.5 to keep up at all...lol

Steiner, thx! That would be a Dodge Ram 3500 with a 5.9l Cummins, for example? I think I could like it :)

the lly is the latest engine, the injectors on the lly are made for easy removal and repalcement, so if injectors go out take it to the dealer and get it back very quickly, have u heard all the trouble ford is havin with the computers o the 6.0's, ford dealers will go down on their price a lot though

I bought my wife a 2004.5 Dodge 600 cummins 4x4 auto 3500 quad. 325 horse and
600 foot pounds torque... And a 7-year warranntee......(the deal cincher) So far no major issues tons of power decent economy for a 7000lb truck on short hauls, school, supermarket etc. I still love my GMC daily driver at 300,000 km. Technology in diesels has skyrocketed in the last 5-7 years. Hi horsepower/torque, High price as well....

Been doing some research on the 6.0L - it appears they have issues in general up until about 2004.5 and later. Maybe that's because the 2004.5's and later haven't actually broken in yet. But thus far there's no coolant spewing out the overflow bottle, etc.... Our 2005 runs strong and good. *knocking on wood realizing he's talking about a Fix Or Repair Daily*

all of chevy's current gassers consume oil faster than my 265,000+ mile toyota does,Not true,My gasser dont use any oil.I change it every 6000 miles,and change the oil filter every 3000 miles. And Im running 14's in the 1/4 mile with just a few bolt on's.. ):h

I'm still in the market for a good diesel truck, and have looking for older PSDs, when a few guys told me the Chev wasn't worth it. I'll tell ya what after pricing the used fords and comparing them with the Chevy for the same year I would have to say the ford is twice as much. For instance 1998 K2500 HD 6.5 131,000 mi $8300 1999 F250 PSD 115,000 mi $17,500. I could restore the Chevy for that difference in price. I'm not worried about getting blowen away by a PSD or cummins, I just want a good truck for a good price.

Dave the 6.5 has gotten a bad rep from early fails, right about time GM got the 6.5 fixed they shifted to DMAX, a 6.5 can be modded to make same power or maybe a little more than the stock offerings of the others, once you start modding the others because of inherent design differences of injection, higher boost pressures, lower CRs they will be capabale of much more than the 6.5.

But you already did the math take a 6.5 in good health put in $5K or less and you will have enough power to pull an 18K load if the need arises, so 8.5K plus another 5 you are still only $13.5 K into the vehicle tweaked to give 200-240 Hp at the wheel depending how far your need for power takes you; find a later model GM 6.5 and mod as you can afford it and you won't be disappointed.

Dave,

I wanted a good occasional work truck / commuter without paying a fortune. Bought my '93 two years ago, put a few thousand in for upgrades and am happy. Don't need major size, speed or hauling capacity. A few times a year I tow 8-9,000 lbs., otherwise use it for light hauling. The GMs ride well, parts are fairly cheap, and the transmissions hold up well. It's been a good value. Plus: I just like the truck's feel & personality. Sometimes I dream of a newer, faster truck - then smile when I think of the money I've saved....

On this forum (+ a couple of others), you'll get good info and backup as well. Good luck in your choosing your truck. Keep us posted.

Hi,

I would take an LLY used or noew, no problem, and no fear, No Worries!! Just because of the changes they made to make injector service easier!!

Take care

WIll

There is one thing I REALLY dont like about the PSD 6.0....only 10 headbolts per bank and they are TTY bolts!!! : pissed beyond belief smiley :

DMAX uses 22head bolts per bank at least and the dummins uses head studs I think....someone smak whoever did that at Ferd....

You mean smack whoever at Navistar decided to use 10 head bolts, and praise Isuzu for making such a nice diesel motor for GM. With aluminum heads no less. By the way, that is why you need 22 head bolts.

My old 6.5 did 0-60 in 8.5 seconds last winter. Once summer hit it went up to 12 seconds. It's not a bad motor, but it is a light duty diesel. Use it for commuting and light hauling all the time and you're not likely to have problems. Do non-stop towing with it and that's another story, as I found. Trying to compare it to my new Cummins? No contest...

That said, I do miss my old truck, and sometimes second guess my decision as the old truck was a lot of fun. Then I remember that now I have a quad cab and a manual transmission, things that I had always regretted not getting with the old truck, as well as the peace of mind on my long trips (which I take a lot of). The peace of mind was something the 6.5 never gave me.

I am 80% sure that the navistar 6.0's also use aluminum heads too....

Good thing you live in Florida. The Powerjokes are all on tow trucks around here when the mercury falls. Seems they really don't like the cold! Other than that, they seem like a pretty good truck. Look really good with a 6" lift and 37" tires too!:p

Nope, the 6.0's do not have aluminum heads.

I built a 300+ hp 6.5 complete with mechanical 4911 injection pump wide open, 18:1 pistons and a short 3 inch straight pipe. It hauled ass and towed well, except for cooling issues in hot weather. Then about 2 years ago I was pulling a hill towing a 7500lb camp trailer and a buddy of mine passed me with his stock 97 cummins towing a 4 horse trailer. We were about the same weight. When we got to our destination I asked him what gear he was in and he said 5th, I was in 4th with egt's at 1200 and not much pedal left. He said he still had more and his truck has 3.55 gears and my equivilant would be 3.73 due to my larger tires. Two months later and my cummins was in and currently puts about 400hp to the wheels and usually never sees the need to shift out of 5th gear until the water temp climbs too high. He says I don't play fair, I say he will never pass me again!

I like 6.2's and 6.5's but they are not in the same league as the heavier duty engines. Plus when I found that my last spare 6.5 block had the dreaded main web cracks, I decided to try something else for a while.:rolleyes:

DC - Do you have pics of that Cummins powered 'Burban?

I, too, would be interested in seeing pictures and getting details of how you did the swap. My friend may be interested in doing something similar. Plus you said you almost never shift out of 5th gear... I'm assuming that means you also put in a manual transmission. I'm impressed! :)

I will have to take some more pictures since my photo album crashed.Censored

I found my original pictures that I posted on the Dodge TDR hope this works:http://www.turbodieselregister.com/forums/showthread.php?t=95125&page=1&pp=15:ro) ):h

I am suitably impressed. You do good work! I always thought that a Suburban with a Cummins would be the ultimate SUV. Very nice work, indeed. I'm kinda surprised you aren't getting better mileage, but I'm guessing that has to do with the fact that you're pushing a giant brick wall aerodynamically.

It looks like, from looking at the tach, that the 6.0 redlines at 4250rpm. My old 95' 454 redlined at 4000rpm. If this is right, correct my if I'm wrong, I don't want a diesel that runs faster than a gas engine.
