That Vett is set up for the 1/4 mile better than most cars from the beginning, sense it does have the lower 3.4 Gear ratio. The Vetts engine only being 1.ltr away from the Viper’s, topped with extremely high compression ratio, and multiple engine changes over the past 5 years in order to get there after playing catch up for the past 10… Id say a super prepped LS7 Z06 that has those tires should be able to run that time at that particular elevation.
I guess what Im saying is that, if you design your vehicle to do one thing its going to do it better than it did stock. In 1997 The a Viper GTS made an 11.7 pass completely stock. It must have been a prepped car, but the current Viper has trouble doing any better than that, I think because as the engine has been upgraded it is more of a top end engine now thus taking it a while to reach the popper RPMs causes but such a high gear ratio. But its torque is still amazing compared to all other engines, its simply geared to high for traction or consumer purposes.
