The Viper would have killed it in a stoplight match 385 tq on the Vette to 465 tq Viper, also the V10 starts hitting that peak torque at 3800 rpm while the hp keeps climbing up to 6,000 rpm.
On the track however the ZR1 might dance around the Viper! Though the Viper was made for the track the Corvette ZR1 was much more refined. I still would have loved to see them head to head! Both are amazing cars!
