I have a 2000 GMC Sierra 4x4 with a LR4 4.8. My 8th letter in my vin is V. When looking at 5.3 crate engines for that year specific application almost all companies i've seen specify their engines will only work with vin's with the letters t and z. Can someone please explain what the difference is as I know the blocks are the same from the 4.8, 5.3 and 6.0. Thank you.
