I picked up a super clean '05 AWD Silverado SS about a month ago and have been looking for a place with some good info about modding it. Hopefully I'll have it ripping low 12's or high 11's this time next year. I'm already starting with a fairly fast stock truck so 13's NA shouldn't be too far off and with a 100-150 shot I should hit my goal. I've already built my transmission with servos and the Transgo HD-2 kit and I have HP Tuners but I haven't done any tuning yet...you think this will get me to my goals of a mid 13 second NA truck?

Planned mods...
Headers (no cats)
Hooker Maxflow 2.5" true duals
TSP Torquer v.2 cam kit with 918 springs
roller rockers
roller lifters
CNC Ported LQ9 or LS6 heads
Victor jr Intake
100-150 shot N2O
