But even while road racing...more torque down low makes up for the less shifting with a high rpm engine. Check out the Head-to-Head M6 v A10 ZL1 lap...the LT4 make so much torque, it could just run out the gears, even at lower rpms.
C7.R does damn well in competition with a 6000-some redline.
Typically, high torque engines are larger displacement, and have a lower relative redline. And a low-torque engine
needs to spin higher to make up the performance, like the Voodoo engine in Mustang.
The LS7 was that "sweet spot", balancing high RPMs, with high torque. There hasn't been an engine since then that could do the same sort of thing.
You'll rarely find both in the same package...would be wicked if this "Spin Tron" was reliable.
