I found a 5.3 from an 07 that was wrecked at 7k miles it does come complete with everything including the wiring harness. that is complete with everything except the ac compressor and the computer. I am not a carb guy at all and everything about a late model fuel injected motor is appealing to me. I just dont want to feel like i am being TAKEN. Ive seen other posts saying that the 5.3 is common enough at all the salvage yards that you can practically buy them for a song. there is a huge gap between a song and $2100. until i saw all these motors come up for 800-1200 bucks, I thought it seemed like a good deal with the complete motor and trans. I guess it is appealing that it only has 7k and the others ive seen selling for so cheap are 60-70k and up on the mileage.

So, I guess the question is whether or not $2100 is too steep of a price for a 07 5.3 with the 460LE, wiring harness, starter, alternator, water pump, etc. (all but the computer and ac compressor)

Thanks in advance for any help.
