Generally my '01 Silverado with 6.0L has a cold start knock as well. I'm about to break 160K on my truck, and I'm not a bit concerned for that knocking noise. As far as I know, all the LSX truck motors do it pretty much. I wouldnt pay no mind to it, if you have good oil pressure, leave it be. I've heard its something to do with the intake, I've heard piston slap. Either way, it aint hurting my truck.
