Well, I got a slightly bigger 6.0l cam for my 4.8 and am going to swap it myself that way it will be worth it for the little gain I will get. My question is this, my truck has about 44,000 on it with some occasional towing on it. I plan on keeping it for a while and don't really want to have to dig into it again at least for a while, (until 100,000 or so) Now, is it worth it for me to go ahead and change the timing chain and gear set now or do I really not need to worry about it? Could there be that much wear on it now? And waiting to see how much slack is in it when it is torn apart is not an option, I need to order the parts now if I'm going to do it.
Thanks
