i have the motor to an ls1 that came out of a 2002 ss aniversary camaro. i am going to put it in my 2001 silverado which has the 4.8 as of right now. I am using my intake and all of my other accessories and of course need a retune. Is there any information that I need to know so that i don't run into some problems? And also I am looking to put a cam in it but not sure which one would be right. any information would help, thanks
