Looks like a spammer attack...lol

It did cross my mind to get a junkyard 6.0 and toss on a pair of new l92 heads and a different cam. How strong are the bottom ends on the stock 6.0s? Should I look for a lq4 or lq9 and how will I know the difference? I want to keep within the 03-05 model year so theres no additional hiccups.
