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.

From:
http://www.chevroletperformance.com/...2397&engCat=ls

"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
Yes 470 TQ! I believe the intake and exhaust have been modified for the Z/28, so the comment of over 500 is possible.
