    Default 5.3 to a 6.0 swap

    Im looking at putting a different motor in my truck right now i have to factory 5.3 in it but i was looking at putting a 6.0 in it. What would all have to be done would i have to buy a new computer or could i have my old one flashed. I know i would have to have it tuned and what not, but i'm just looking for a little input from everyone!
    Thanks

    should be a direct swap, then just have the tune updated for the 6.0. you might want to consider the 4l80e tranny if your truck doesn't have one already.

    Wouldnt putting in a bigger cam and crank push the displacement out??? sounds cheaper then a whole engine/ tranny swap....

    A cam has nothing to do with displacement.

    New heads and getting it bored out would make the difference up, I personally like the 6.0 way better and that's from personal experience. I would research parts interchangeability between those two motors, you would be surprised what GMPP has in there catalogs if you have the $$$$$

    He has another thread saying he's burning oil, so the motor is probably shot.

    I second the 4L80e.

    nope just drop in and tune.

    maybe a tranny.

    When you get your 6.0, swap in some cams and beef it up before dropping it in.

    Is the 6.0 overhead cam?

    Consider this. The 6.0 is capable of producing a little better torque numbers, but the 5.3 is a solid performer. I had a 2002 1500 with the 5.3 ltr. When I wanted more "go" and "tow" I opted for a whipple supercharger. I will tell you that thing hauled A$$ following the upgrade. In all, it ended up costing me about $2900 but I had a full size 4X4 that would easily run with most anything I came across on the roads. Any time you decide to swap an engine to a different config, there are a lot of little costs and changes that can really add up. Not sure what your state's emissions standards are, but with the heavily computer controlled engines of today, you need to be very careful that you don't end up screwed when it comes time to have it tested. The numbers are predetermined and your truck will need to meet the stardards for that model. The tester/computer won't care how much work you've put in. It's simply a pass/fail.
    I ended up moving to a diesel because my toys got bigger.
