Let me be the first to apparently mention this:
The heart of the Z/28 is the 7.0L LS7 engine. The LS7 uses lightweight, racing-proven, high-performance components, such as titanium intake valves and connecting rods, CNC-ported aluminum cylinder heads and a forged-steel crankshaft to help produce an SAE-certified 505 horsepower (376 kW) and 481 lb-ft of torque (652 Nm).
That's 11 lb-ft improvement over the Corvette's version of the LS7 (rate 470)and, packaged in a 600+ pound heavier car, I'll thank Powertrain for finding that. That is very important for this car and it's intended usage, and far more significant than a few more horses...
