    I keep changing my mind on things but I think I finally have it narrowed down between two vehicles. The first is the 2000-2003 Ford F250 7.3 powerstroke ext. cab. And the other is a 2003-2005 Chevy 1500 5.3 v8 gaser ext. cab. I know that with the powerstroke, I won't really have to worry about trailers that are too heavy or not having enough power. But yet any repair will be pretty pricy. And with the 1500 I don't have the towing capacity of a diesel (not that I really tow too heavy of loads right now) but the repairs should be much cheaper than a diesel. I just don't know if I want to lose the capacities by stepping down to a 1/2 ton truck.

    What are you smoking dude. A 7.3 with CAI, tuner, and full exhaust won't be faster then a 6.0, 5.9, or a duramax.

    A decently set up 7.3 will no doubt outrun/outpull a stock 6.0 or 5.9....I've done it in both my 96 and 01. K&N intakes, edge evolution programmers, and turbo back straight pipes. I'm talking lightly modded 7.3 to stock 6.0/5.9's as I think the topic was mentioned.

    Out pull yes, but out run I doubt it. The 6.0 has such a nice curve compared to a tuned 7.3. Yes the 7.3 might make more power peak to peak with the 6.0 being stock, but the curve is so peaky and short it will not outrun the 6.0 stock. You may get one from a roll but not both trucks from a dig just because of the variable veins in the turbo on the 6.0. I have spent many hours at SCT, Superchips, diablo, and delta force as all of them are about 15 minutes from my house and they often need donor vehicles as I have donated 5 cars for almost each of them to tune.

    I'm not smoking anything I've personally raced them with my truck and beat them. my dad and two of my friends have duramaxs and i even beat my friends 06 duramax that had full turbo back exhaust and banks ram air intake but stock programing. and my other buddy has an 05 dodge ram cummins and my truck spanks it really bad...

    have you driven a 7.3 with a DP tuner? if not you have no idea what your talking about a stock 6.0 is like 3 truck lengths behind me at 90mph

    you guys can't compare a modified 7.3 to STOCK vehicles. :hammerhead: :hammerhead:

    for example, my 04 cummins with a smarty will outrun any 7.3 with a tuner. why? because a 7.3 can't make 430 rwhp with just a tuner. and a 6.0 with a good tuner will beat any 7.3 hands down. stock 7.3 powder rods can't reliably handle over 400 rear wheel horsepower anyways.

    i prefer cummins. easy to modify, has more longevity than the other motors. however, if you're not into hot rodding, find whatever you like and run it. they all have their own set of problems

    Yes I know a 7.3 will not beat tuned cummins or duramax that has nothing to do with this thread, the guy doesn't want to spend alot of money on a truck so for 10 to 12 grand you can get a pretty good superduty with a 7.3 and do those few mods to it and it will do anything a stock 40,000 dollar truck will do so thats what i'm trying to say here.

    That is my typical arguement, as mentioned above. I'm a Ford guy, but the 6.0 just scares me, I'm needing to get another truck, and there is an 06 with 25k miles at a dealership in town I would love to have. But as far as doing any tuning to them......I've always been told by a few guys that work on them, to keep em stock and service them regular if you want them to last...so until there is a compelling arguement the other way, 7.3's seem pretty good to me. Good tuning, upgraded hpop, injectors, turbo, you've got a truck capable a whole lot for not much money if you get the truck itself bought right.

    6.0's aren't bad, but they need help. the two biggest things are to put head studs in it and get rid of the EGR cooler system.

    this video will help http://www.youtube.com/watch?v=RW7JEHLYyJ4
    (i don't agree with the exhaust portion... you don't need a tuner to put on an exhaust)
