GMC 5.3 vs. 4.8L V8

Ok, any big difference between the 5.3L V8 and the
4.8L V8? I'm closing the deal on my truck
tomorrow and am curious why I'm choosing the 5.3L
V8? According to the specs in the GMC Book, the
4.8 gives 270 horsepower and the 5.3 gives 285.
Doesn't seem like that much of a difference. Do I
really need the larger engine? I dont plan on
towing anything, but you never know. Maybe in the
future tow a small boat, but would that make a

HELP! I don't know what to do.
(It's only $688 more money but, that's the $$ I
could use for my cover.)

    will you ever tow? the 5.3 has LOADS more low end torque than the 4.8 does. the 5.3 is basically a very peppy engine from stop, while the 4.8 is not.

    highway driving, you shouldn't notice too much difference, since the horsepower numbers are pretty close.

    The 4.8 will get a little--not much, just a little--better mileage.

    If you tow or haul heavy consistently, you will be very very thankful for the 5.3. otherwise, you probaby won't miss it too much

    Go with the 5.3

    Your spending 30K on a truck anyways whats another $700???

    Also reslae value will probabaly be higher on a 5.3 than a 4.8

    Milage from what i have heard is negligible.

    I agree with Ryan. If it were me, I would go for the bigger V8. $700 is not much more in payment for what you are getting in a more capable and satisfying truck.

    I think the 4.8 is still a great engine and has lots of power, especially when compared to the competition's specs. If you are only towing a light load, and you are not used to a bigger V8, you may never complain at all about the 4.8l. If you tow a lot, up hills, in high temp locations, etc., you owe it to yourself to consider the 5.3l.
    As CDean stated, you will see little difference, if any mpg advantage with the 4.8 anyway. Your only real higher cost is the initial $700. To me, when you consider tow ability, as well as resale value, which definitely will be better with the 5.3l, it is an easy decision.

    From what you stated you really don't require the 5.3L engine. I have drove trucks with both engines and you can't notice the difference. Yeah its only $700.00 for the larger engine or as I see it is $700.00 for a 6% increase in power. Its you money however and the final choice is up to you.

    ..the 4.8 will be useless towing....(at least if you want reserve power)...the 5.3 will hold up better....pass better..take off better..and MPG won't even be may not tow now...but the slightest load and you will be wishing you had got it..

    if not....A.M.T.!

    We are all gettting scammed. Everyone offers it but then when you hold em to that offer they back out WHY???

    1 Month and 2 Days you all can send me some beer ok???

  • swobigswobig Posts: 634
    both are close in size, power, mileage. $700 is a consideration. Of course you'll get more for a 5.3L, but you'll also pay more for it so it's probably a wash. Ford seems to sell more small V8's than GM does and it's the way it probably should be. I have the 5.3L, but wish I had the 4.8L for economy. Couldn't get the 4.8L with the LT package. Tell you what - get the 4.8L and give me a call and we'll swap engines - serious!

    I came up with a plan for someone to get a 2500 with the 6.0 and swap it into my 1500. Never found anyone to do that :(

  • mgdvhmanmgdvhman Posts: 4,162
    ..wonder why?

    and couldn't do the install....LOL
  • ryanbabryanbab Posts: 7,240
    yea dean. No I just got this plan to have the only 1500 Silverado with a 6.0 in it. Find someone that only wanted the 5.3 in a 2500 have em get the 6.0 and id trade em the 5.3 for the 6.0. Sounded good didnt it??? That plan died.

  • swobigswobig Posts: 634
    I wanted a 3/4 ton 4X4 with the 5.3L - wish I would have known sooner Ryan...
  • mgdvhmanmgdvhman Posts: 4,162
    already has the first and only 1500 6.0....

    your parents bought you a nice truck and now
    you're unhappy with it. what's up with that?

    Truckchic, the 5.3 is probably more motor than
    you'll ever need, but the one thing you can count
    on is that when you want it to go, and i mean go,
    it'll leave any 4.8 in the dust. i also agree
    with the others in that if you do decide to
    unload it, you'll get all your money back for the

    Adds about $500 to retail value over a 4.8L. According to Kelly Blue Book.

    So, it only costs a couple of hundred dollars and 1-2mpg for a little ego boosting power.

    The 4.8L engine is enough for me.
