I have a 99 5.3 with 80,000 miles on it, is it worth the time and money to put a 6.0L in it, or should I wait and spend a little more money and get an
LS1/LS6. The 5.3 in the truck now is ok, starting to hear rattles and some off noises. Let me know what you think. And is the swap over to a 6.0 hard.
This swap wouldnt be till the current motor goes out, but i just want to see what people are doing.
