Hello, I am new here and just started working on the performance part of my turck. I have a 99 chevy Z71 5.3, We are going to get the Sts turbo and meth. injector for it along with high flow converters and headers. We are about to pull the engine out to get balanced but here is where it gets funky for us. We are wanting to pull the most power out of it as possable.
My question is that i need help with is
1. What heads will give us the most power
2. What pistons, rockers, lifters.
3. What cam.

I need as much help as possible that anyone can give me, we are building this engine to get as much out of it as we can. Please give sug. on products your rec. or that you have used. Thanks for the help in advanced.
I have attached a pic of the truck we are doing the work on

 

How big is your wallet? You might want to post in the Internal Engine section for better responses about building a motor. If you have money, buy a C5R block ($6k+ for the block only) and some C5R heads ($6k+ bare). It all depends on your goals: Daily Driver? Street/Strip? Strip Only?

Be ready to beef up everything in the driveline. I think W2W made 750hp and 900tq (on an engine dyno) with a turbo'd 6.0L.

 

Let's move this to a better section for FI

 

we bored a 5.3 out to put LS1 forged pistons in, so basically a 5.7.
With forged rods and pistons, LS6 cam, stock 6.0 heads with just ls6 springs, STS with GT-67 and fmic, we made 650 on one pass on the dyno. With the heads and the dish compression was about 8.8
