    7.3. The 6.0 can put down some nubers but it has a ton of issues. I would NEVER buy a 6.0l no matter how cheap it is. its not worth the hassle

    depends on what you do to it... they're all pretty reliable, until you mod them... simple exhaust and intake will suffice

    personally id rather have a 7.3L but if you got a newer 6.0 you'll be fine... my cousin has one of the frist two 6.0s to hit las vegas and to date has 2 trannies, 32 injectors, 8 pistons, one cylinder head and one turbo replaced on it. theres nothing really wrong with the newer 6.0s like 04 and up. i personally prefer the 7.3L because its been used in international medium duty trucks under the title DT444E for years. where the 6.0 was designed to be put into a pickup. the 7.3 is just a little overkill for a pickup and i like that about it. the 6.0 builds more boost and builds it at lower RPMs it also seems to heat the EGTs up a little faster from what ive seen in person. but all in ll the 6.0 is a good motor i'd own one in a heartbeat. hell next year i plan on buying one because 7.3s are getting harder to find without ungodly miles on them...

    exhaust, intake, turbo parts and computer... and try to keep the computer tuning somewhat mild. you'll get tons of power and a looooong life out of them. ive seen 7.3s in the 400k range before needing a reman but it was ALL highway and very well kept... ive seen 6.0s with almost 300k on them too.

    You should be able to get a half mill. out of a 7.3 if you do good oil service. The 7.3 is a better engine than the 6.0, later 6.0's aren't bad but I'd stay away from first year 2003's.

    I third a Dodge Cummins.... got two of them sittin' in the driveway. Nothing beats a Ram Cummins that sounds like a 14litre N14 with nothing more than 5" sewer pipe and plenty of fuel....

    The 6.0 is a pos. The 7.3 is a pretty decent engine but I like the 6.5td a lot better which is what I bought and have been totally happy with it. Parts are a lot cheaper for the Chevy too.

    The 7.3 is a good engine, the SD trucks have a factory intercooler and a bit more power than the earlier models, but that's nothing that a little money won't fix. The 6.0 is a good engine too, but I would avoid the first year or so of production. The 6.0 also doesn't like big power being added, over 150HP or so according to what I've read. That being said, I've put somewhere between 30-50K on a 04 6.0/torqshift rig, a CC DRW, and it ran really well and never gave the owner any major problems. He still has it, I'd imagine it has around 100K on it now, a large percentage of that loaded and towing. I've pulled 7-10K worth of enclosed trailer up 4-6% grades at 80-90mph all day long with that truck.

    No offence, but the 6.5TD is not in the same class as the 7.3 PSD. When the 6.5TD was still in production, along with the PSD from Ford and the Cummins from Dodge, there were TWO options for a diesel pickup at that time.:wink1:

    Not saying the 6.5 is a turd, it just isn't built like the other engines talked about in this thread. the 6.5 is a great engine for what it's designed for,like the 6.2.

    If you like your 6.5, and are GM loyal, you'd die happy owning a Dmax.

    your point is?? my truck has it from the factory.... hmm oh well

    guess the fact it isnt available from the factory should stop it from happening, attention everyone with fuel injection on a chevy truck older than 87, please remove your efi and return to carburetors...:wink1: :D
