whoever reads this can you give me suggestions for what performance parts I should put on my 4.8 Li engine in my 2000 silverado. I want to go from 270 HP to 300+++. any suggestions welcome.

 

There's a HUGE amount of discussion on this board regarding air-intakes, headers, exhaust options, cams, new heads, gears, torque converters, forced induction (turbo & superchargers), etc. Just hang out and 'listen' to the discussion threads, read some of the older conversations that have pretty much ended, and search on stuff you don't understand. Like some of us, you'll learn a LOT!

And welcome to the board!
