Longevity and HP are inversely related on any engine. So any of the older diesels from dodge or ford will last a long time. They both get better fuel milage.

I would say that's only true to an extent. Yea a stock chevy 350 is going to outlast one putting down 500+hp in a drag car, but stock v. stock a newer, more modern vortec 350 is going to outlast and outperform an old 350 by a long ways. The same goes for modern diesels. The reliability seems to be more related to the electronics involved in running a newer diesel being more complicated (and thus more difficult and expensive to fix) versus the simpler almost entirely mechanical design of the older diesels. If you gave me a choice between a 1995 F350 7.3 Powerstroke, a 2005 6.0 Powerstroke and a 2011 6.7 Powerstroke my order of preference would be '11, '05 then the '95

There are a lot of old chevy 350s running around. Newer or not when you increase HP you decrease the life of the engine. Those complicated electronics have caused more repairs for newer diesels.

On the same platform yes, but to say that the new 6.7 PS is less reliable solely because it makes more power than the 7.3 PS is BS

Good choice. I had a 93 club cab before I bought my 96. If it is a 3 speed auto it is an old school 727 torqueflight and you should be fine if you keep the power close to stock. Put in a full set of gauges on it and enjoy life.

Here is the new money pit, I mean tow rig for the Jeep. Its a 1990 Dodge D250. New trans (a built 727), rebuilt motor, new brakes,hoses etc. It has some rust on the roof, but its clean otherwise. I plan on doing a resto sometime in the future. It runs great and gets 20mpg.

Only time will tell. However that CGI blocks they use on it will be a huge help.

Have a 92 5.9 Cummins, over 750,000 miles, and always had a heavy trailer. Not one problem.

Nice choice I like the old 1st gens. Im not sure if the 90s got an intercooler though I think they got them in 91.5. You can get upwards of 350hp out of that VE injection pump it has if you need a little more grunt.

I have had a 91 ford 7.3 idi a 95 ford 7.3 powerstroke and a couple of 24v cummins and got rid of them all. Ill stick with my 97 12 valve now as you just cant kill them and their stupid reliable

Here in Indiana we have a very highly respected mechanic/ offroader in nappanee named Barney. His shop is called Barney's 4x4. He's got a 1st gen too with 500,000 and it's all stock with a trans rebuild at 175,000. It has a 4 link rear with air bags because t pulled hog trailers all it's life. He said trucks will go forever if you keep them stock. Just some heads up. This guy is the best of the best a

Good looking truck, congrats!

I love watching the debate about which truck is better. Kinda like asking of someone prefers blonds or redheads. There's no "right" answer, but you'd sure swear there was by some of the responses.
