    Im trying to get some input on these. Which is better or they about the same? Id like to put a 7.5 blade on, and will be towing a boat trailer and snowmobile trailer. What do you guys recommend? Ive read that a lot of people say that a 4.8L will do just fine, but if you ahve the money get the 5.3L.

    both will do the job, but the 5.3 will get better milage in the long run, not working as hard.
    depending on the year you also have the 6 speed auto with the 5.3.
    My truck just rolled 10,000km's recently which im told is when the fuel milage numbers should start to get better, on an 80/20 highway to city tank recently i got 740km's on 88L of fuel which i don't figure is too bad all things considered.
    My dad has a same year 4.8 and they don't tow anything with it, just quad or sled in the back, he gets pretty decent milage comparable to me which brings in the driving habit aspect into the milage. I will tell you tho that the 5.3 will hold a gear on cruse control longer than the 4.8.

    Neither one of us has ever kept one long enough to tell you about longevity of either.

    Both motors are almost identical. The 5.3L will pull a little better when it comes to climbing a hill. Go with whichever one that comes with a better truck (less miles, no rust, better options, your favorite color, etc).

    mines a 4.8 and it pushes fine still with 126xxx miles beyond that i dont know but still sounds like any new truck i go near. had a small problem with power steer pumps at 110xxx but i blame it on a junk part from autozone / delco

    I have the 4.8 in my 2002 Chevy 1500. It has realy good power and is pretty "peppy." I have only driven a truck with a 5.3 a few times so, I can't realy compare the two. Both are great engines and you can't go wrong with either one.
