Hi guys, a friend who sells me a 6.0 bored to 4.065 "(3 Gen) with 243 heads ported. I will put this combo on a 2003 Silverado with 5.3 RCSB (I will put all the accessories from the 5.3 to the 6.2) as you see it is an improvement somewhat cheap but I have some questions.

The goal of this project is to get you to do 12 seconds or less in 1/4 mile 1900 meters (AMSL). The truck currently has a 60e stage2, 4.10 gears with locker, stock torque converted

1- I know that I will have a lot of compression, does anyone know an approximate of it and what gasket heads should I use?

2- What camshaft and torque converter kit do you recommend?

3- Will the fuel pump and the stock injectors be enough for that 6.2s?

I'm good? Or do I withdraw from this expensive hobby lol

Any good or bad tip is welcome. Thank you!

We need more information. What is the main use of this truck? Daily driver? Will you tow anything and what would you be towing? Is it going to be a street/strip brawler?
What is the rpm red line you will run the engine up to? Are the pistons flat top? What is the compression height of the pistons?
This info will be a good starting point for some of the info you are asking for and it is needed to answer your other questions
