alright first off i have a 2001 z71 5.3 auto, and i'm looking to do the ls1 swap

i know it's pretty expensive but i think i'm in love with ls1 engine(trans am's are badass )

my question is, do the ls1 engines lose some of their flavor with a 6+ inch lift? and i'll definately be offroading and want to know if i'll be happy with the purchase

also i'm in tyler so anyone know any good shops around dallas that wont charge a bundle for the swap would be appreciated

thanks in advance
