Im new to the newer vortec trucks! I was looking thru upgrades or small Swiss here and there to create more hp/tq. Would say, the ls1 intake bolt up and work properly? Small ideas like that have came to mind....any idea, cheap and/or expensive would be awesome!

Well I researched it all. Found a few cool things I could do. Just didn't know if there may has been easier routes or cheaper upgrade/swaps. But I'm pumped!
