well i opted for finding a used 5.3 or 6.0 rebuliding it and putting it back in my truck but my dad wants to just put a new crate motor 5.3 in which will be going in next week. My only deal is this motor is comming with a 3 yr 100k mile warrenty...is my modding time over for right now or will cam and other stuff void the warrenty?
