Although, this is obviously not as good as comparing dyno graphs, the Ferrari can clearly hold on to its torque for much longer than the Vette (3250 rpm vs. 1400 rpm) . It also doesn't peak at a very different rpm than the Vette, so its low-end torque probably won't be bad at all. All that technology in the Ferrari does replace displacement.

As far as I've heard, the Z06 gets a 3.42 rear axle with a 2.97 first gear. The Ferrari has a 4.30 rear with a 3.29 first gear. They both have essentially the same diameter tires

342*4.3*3.29=4800 ft-lb
475*3.42*2.97=4800 ft-lb

And the Ferrari's lower gearing means that its engine will reach 5200 rpm long before the Vette's reaches 4800 rpm. I don't think that the (probably) slightly better torque curve in the Vette off-idle is going to make a difference.

In any case, I'd take either of them .
