I just bought a used motor out of a 2000 silverado. i am planning on building up as much as possible, going to run a single turbo on the intake side, i am having trouble picking parts, im going by the moto, 'Do it right the first time'. so price isn't too much of a worry as it will be going into a show truck. I would like to see 700 whp so 8-850 hp at the crank. i see there is alot of controversy on what kind of heads are best. and i have decided i am going to run a dual intake manifold. and insight on heads, brands, cams, bottom end would be great.even though i would prefer to leave the bottom end as is. i would change things if i need to, to get the power. it is a efi. Im not sure if i need to delete the AFM/dod, or what else that would change.

You will need better connecting rods no matter what. That power level is beyond what you should run on the smaller "I" beam connecting rods. Get some H beam rods from a newer engine or buy some aftermarket rods. I would upgrade the piston at the same time. Gap the rings properly and you'll have an engine that can make the power you want without issue.

Just about any camshaft is a turbo camshaft. Pick yours based on how you want it to behave during normal driving and what kind of stall converter you think you want to run. Brian Tooley Racing has a few to pick from, even the Isky Triple 12 camshaft or the "Sloppy stage 2" camshaft from Elgin. You'll want a strong transmission to handle this power too. Th400 or 4L80e is what I would do.

There is no AFM on that year engine.

Heads and pistons should be selected at the same time so that you can achieve your desired compression ratio

more compression means it's a better driver out of boost, at the expense of knock resistance and lower peak boost

staying stock, the heads is has are good. Staying OE, 243s are good

After that, the sky is the limit. Pick a number to spend and a chamber CC and have at it. With the 5.3 bore you have to stay cathedral

the heads that i currently have for it are the 706 heads. would i need to do anything with those? or use a different head?
I have never dealt with a turbo before. So would 12 psi get me to my power goal?

I wouldn't target a boost number, it's not about boost. You can put a tiny hair dryer on there that hits 30psi and make probably 400 before the thing chokes at 5500rpm

or you can put a monster ****** on there that hits 6lbs but doesn't spool until 4500 and makes 600

Im not a turbo sizing expert so im not even going to suggest anything other than HP is about flow, not PSI. Boost is just a measure of restriction in the system. 12psi at 1350cfm makes a lot more power than 15psi at 900cfm

edit: 706s will get you there, but they aren't the best flowing head so you will
see a lot more boost to make the same HP than say a 243

I know engines are basically air pumps. the faster you can get the air through it the more hp you'll get. though it took you saying that for me to get those dots connected so thank you!!! lol.
