This is my Chevy Silverado Z71 Ext. Cab Short Bed. It has the stock 5.7 350 V8 but not stock. So far I have done a Helix Thottle Body Spacer, K&N Air Filter, MSD Ignition System,Granatelli Mass Air Flow Sensor, and TRUE Dual 40 Series Flowmaster Mufflers to make it Sound and Flow better. I have a 2 inch Torsion Bar lift that leveled it all out and clear 285/75/r16 BFG All-Terrains on ASA Racing Wheels. I have also added a SmittyBuilt Stainless Steel Brush Gaurd along with 55W Hella Black Magic Off-Road Lights,and Westin Stainless Steel Side Steps, I just added a Superchip and a Granatelli cold air intake around 5/1/05 making me now over 300 Horses
