Correct, however with 12.5:1 compression, direct injection and cam profile similar to the C7 (450-hp, 450-tq estimated out of 6.2 L) it would be possible (particularly with long tube headers and 3" exhaust) at the flywheel.

No mention of this for 2014 however but for a 3,800-lb track car 500 lb-ft of torque is a useful target to have since that is what allows the ZL1 to have better lap times (most tracks) than the GT500 by using it's superior traction to lay down the torque to generate higher corner exist speeds.


"the LS7 uses a 7.0-liter aluminum dry-sump block, CNC-ported cylinder heads, and titanium rods and valves to pump out 505 hp and 470 lb.-ft. of torque."

30 lb-ft could be gained with CAI, low restriction exhaust and tuning
