Nope its true. A base gp gxp with the 5.3 ls4 motor has 305 horsepower. I've seen consistent quarter mile times of 14.3-14.2 all day. My gtp has got a basic 3.4 setup and I'm only runnin 14.1. Ur car could hold its own against a lot of cars. Any ricer, pretty much any mustang v6 OR v8 except for the 05 and newer. U get the picture. Plus uve got a v8. I betcha a lot of us s/c v6 guys would love to have a v8 under the hood
