I don't mean to sound stupid,but I have questions before I try to sell a 6.0 engine. I got it last year to put in my 2000 Silverado, but have since change my mind (keeping the 5.3). It's a iron block with aluminum heads. I'm guessing it came out of a HD truck or something like that. Am I correct?? It needs rebuilding not sure whats wrong with it. Question is how much is it worth as it needs rebuilding? Let me know, thanks in advance

 

6.0L LQ4s are $600-$1000 right now from what ive been seeing.
