Good Morning/Afternoon/Evening GMTC Members, So as you can tell from my signature, I'm compiling a rather lengthly list of things I want to do to my truck including modding the engine to a degree. My plan is to keep my truck and hand it down to my 7 and 4 year old when they're all licensed and legal to start driving. Therefore, I have no plans of getting rid of it anytime soon, if ever. That also means that whatever mods I do to it, I don't want to have a severely negatively impact longevity. As I began listing the things I want to do to the engine, intake, exhaust, etc.. I began thinking.... Should I mod the 5.3 or upgrade to the 6.2? I'm planning to have my current truck paid off in the next 2-3 months and I've considered upgrading when I get back in Country whether that be during my vacation in December or when I'm back for good in early 2013. I figure I could get a 2010 or so used Silverado/Sierra and could probably get a pretty decent deal since I'd be paying cash. If it helps your decision at all, I'm hoping to buy a couple family offroad and water toys in the next year or two so I'll be doing some towing, but nothing that either engine couldn't handle. I really just want increased performance and capability. I also figured that if I get the 6.2, if I decided to still mod it, the mods would just add that much more. On the other hand, the 90 extra hp might stave off the desire to mod much for a while. Therefore, my question is, given the parameters, would you go ahead and start modding the 5.3 for the long haul? Or would you upgrade to the 6.2 and use that as the base for the next 10-12 years? As always, thank you for your inputs and opinions.
