Thanks For The Input. I Wanna Hang With F-bodies. I Raced A 2000 Z-28 And He Could Not Pull Me Much If I Was At 4500 Rpm Or Higher But His Car Pulled Me Bad At Lower Rpm. I Have 17" Rims Off Of Avalanche With 275/60/17 Falken Tires. 373 With G80, If I Go With The Ts224 Cam, Lt, Nelson Tune And Cai Along With No Cats And Duals With Super 40 Three Inch What Kinda Gains Am I Looking At Over Stock, I Just Installed Some Ngk Iridium Plugs And Taylor 10.4 Mm Wires Tonight And It Seem To Run A Lil Smoother...

i have a 5.3L avalanche and bought the same package from tsp except the tr224r. havent put it in yet. also bought a 3200 stall. i would recommend a transgo hd-2 shift kit to help the tranny last a little longer
