Hello, guys I'm a newbie.
I have a 2003 Silverado Z71 with the 5.3 and 3.73's. I have installed a K&N FIPK and a Borla Cat-back exhaust. I want my truck to be a mid 14 in 1/4. I think i'm going to go with a torque converter and nelson tuning next. Will that be enough or should I add a Cam? Thanks for all the info and advice!
