I'm curious about the Z06 and the 5.5 L flat plane DOH with a rpm of 8000+. Possibly a lighter car, less gadgets, more track car, maybe a quicker 0-60. Will GM modify the gears to compensate for the lower torque with the smaller displacement and what about mileage? I understand that the higher revving engine uses more fuel to get to the same output as the 6.2 L.
Interesting times ahead.
