i have a 2000 chevy ex cab with a 5.3 w/3'' cat back k&n fipk and bully dog programer. over the weekend i aquired the following parts;
98 f-body ls1 cam lifters and springs
98 f-body intake and throttle body
ls1 f-body fans
which of these parts can i use on my truck? what kind of performance gains can i expect? i'm sure a nelson tune would follow after any of these parts

thanks for any help!!!
