4.8 pistons

I'm working on a 99 4.8 vortec and I want to replace my pistons but I'm having a hard time finding pistons for it. Can anyone point me in the right direction?

dealer item more or less. Scrap it out and buy a good used engine. Get a 5.3 or 6.0.

you cna also have the block bored out to a 3.905 and use LS1 pistons, and an LS1 crank and have a 5.7, or use a 4in stroke crank and have a 383. A stock LS1 crank will hold 500+ HP and can be had pretty cheap, a 6.0L crank or 5.3 crank is the same stroke.

At that price, you're better off just spending $1k on a good used 5.7 long block or a 6L.
