For those not familiar with it, the LSA was originally shoehorned under the hood of the 2009 Cadillac CTS-V. It's currently rated at 556 horsepower and 551 pound-feet of torque in that application. We have no clue what it will produce under the hood of the Z28, but it will most certainly be a hearty jump over the 425 hp produced in the Camaro SS.
Head over to the Camaro5.com forums to see more detail and gander at some high-res photos. A twirl o' the bow-tie to Jason!
