99 Chevy 5.3 STS Turbo
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.

But if you are stuck on using the 5.3 block, I say get some forged Diamond blower pistons 3.905", Eagle H-beam connecting rods, Eagle 4.000" crank. That would give you a built 383 that should handle a bunch of boost. Futral Motorsports sells Melling stock replacement lifters and I don't know what rockers to go with, I've heard stock ones are pretty good. The cam would have to be more for low-end to mid-range torque because of the 5000+lb Z71. I'd say a 228/226-114 for the 383 and a 234/232-114 for the 408. I'm sure some will tell you to go bigger but those are some big tires and a heavy truck. Nice truck by the way!
