    Default Camshaft Install

    So I've been lookin all over town trying to find guys who will do a camshaft install on my 03 Silverado with a 5.3L LS engine, and I can't find anyone who does much work on trucks. The one place that says they can tune and install the cam is a import place, and the computer program they have told them its a 12 hour job, and even at a pretty reasonable rate (90 bucks is good here, thats Hawaii for you) I'm lookin at $1,100 bucks w/o parts. So I was wondering if any of you knew where there might be a installation guide that is specific to my truck? I know someone made one for the F-body with a LS engine, but they had to take the radiator off, and I've heard for ours you don't need to do that.

    Any help is appreciated!

    Trucks and F-body's share the same motor, just different displacement, as far as a cam swap the are exactly the same, the only difference is the intake manifolds and the accessory drives.

    So would I have to pull the radiator to switch the cams on my 03 Silverado?

    Wow...looks like it might be worth it to have the truck down for a weekend to do this. Do I need to change the valvesprings and pushrods, or is that something that is just a extra mod? Is it worth it?

    Thanks for the videos, they make it look a lot less intimidating!

    I would recommend springs at the minimum, pushrods definitely don't hurt, but depends on your cam.

    Correct me if wrong, but if you go with a big enough cam you will want to upgrade your valvetrain. If not, you will end up hitting a valve on a piston.... and you will then be replacing your bottom end :(
