First I want to say hi because im knew to this forum, and second i want some suggestions. I have an 06 Silverado 4.8 Vortec. reg cab, long bed. I have a K&N cold air intake and a flowmaster exhaust. I am happy with the low drown i have right now but i dont have the power and pep when i put the peddle down that i want. This is my second truck and i dropped my first one which was a ford and it looked good but i want to go big with this one. I have a 3in spindle lift and 1 1/2 lift blocks on the leafs in back. Any suggestions on more lift and more power would be awsome! thanks to all!
