not a great power-to-weight ratio on the GTO. also depends on the year, some of the first gen GTO's had only 350hp, until the 400hp engine was introduced. 2004 models do a 14second quarter mile, and 2005+ 13.6...

i pulled hard on a fully modded 2005 (bolt-ons) GTO this fall with no contest. GREAT-sounding exhaust though! i love the rumble of those LS-V8's!
