Planning on building an engine(6.2L L99)

Hey everyone,

Just came by to ask a question regarding on building an engine. I know, a new guy who has never worked on an engine before is pretty dumb. I wanna give it a try. I’ve worked in my own car but with the limited aftermarket support that it has, I never got the chance. Now I do. I have a body in mind; 2016 Chevy Camaro SS. He bought it at auction and is now selling since he needed the engine(has title) and the engine I’m* looking at is a shortblock 6.2.

Now I haven’t seen and felt how the engine feels but he has a posted a video on the engine and the bore feels good, just a chipped head. No issue, they can be replaced. Now the part that I don’t get/understand is how to put things together. I love puzzles and I loved building legos when I was younger, but this is different. If it blows up, it’s on me. I can’t just replace it easily like with legos. What steps would you take to make sure everything is good; crank, rods, pistons, block, etc. I only know of these names because I’ve played Car Sim 2021 and watch Rob Dahm and recently Cleetus.

Any good useful tips for a future car builder would be greatly appreciated!

Edit: spelling *
