I have a 2006 Silverado 1500 5.3 LM7 ,& im planning on going Turbo. Before going turboed I need to rebuild my motor ,but I'm on a budget. I know I'm going to have to spend money anyways . My question is if I rebuild my motor with a brand new crank shaft,& brand new pistons etc,etc. can/will my motor last a great while?? I don't plan on going crazy with boost. Maybe between 8-10 pounds of boost or somewhere safe.

The bottom end is fine, if anything just swap over to GEN 4 connecting rods as they way stronger than GEN 3 rods. If you plan to push past 500-550whp, you want the better rods.
The heads don't make noise, it's the lifters/valvetrain that tick/clatter in all these trucks.

bud, hotrod mag took a 160k junk yard 4.8, regapped the rings and set it up on a engine dyno with twin turbos, the bone stock junk yard motor spat out over 1k hp with over 50 dyno pulls.
They claimed after inspection it hard Zero damage and was confident it could take that abuse for quite some time.
