1999 Crew cab OBS 5.3 Swap

I disagree. It depends on what you are going to use the truck for. If you are planning to do alot of hauling/towing then def track down a 6.0 but if not then just go with the 5.3 because it will already be a huge improvement over whatever you are taking out.

Of course you do.

Back when I had a stock 6.0 I was making more power then cammed 5.3 L and making better MPG, now I am cammed I make even better MPG and more power. Why would someone want that lol.... Just sayin
