I have the 5.3 H.O. motor that I have added CAI, LT headers, and a 93 oct. Blackbear tune to. It has woken up quite a bit. I have also added a vette servo, and 456 gears to my truck aswell. Now what would be the next big improvement I could do to my truck, since Im now getting used to the gains I have added? Cam, built trans? What do you guys think?
