No on the Vette and No on the Hemi.. My Hemi was under 500 cubes and went 9's in FAST trim, big cubes, balls to the wall the Hemi will rule. IMHO. Pure Stock racing might be a different story because of the reasons Joel pointed. Give the Vette a better exhaust, bigger tires, superior ignition than what the factory supplied it's hard to beat. All the cars would suffer but the Vette would suffer enough to make this class a race, maybe..
