General Motors has grown its E-Rod family by two, adding a 505-horsepower 7.0-liter LS7 and a 556-horsepower 6.2-liter LSA to its line of emissions-friendly V8s. The General chose to show off the new forced-induction engine by plopping the mill in a Superformance Grand Sport replica. With a feathery light curb weight of just 2,500 pounds and a potent 551 pound-feet of torque on tap, this machine should be an absolute tarmac terror. Behind that supercharged small block sits a Tremec six-speed manual transmission and a four-wheel disc brake system designed to bring the whole party to a stop in a hurry.
GM says that it is currently working closely with the California Air Resources Board to ensure that the E-Rod LSA can be used in pre-OBD-II vehicles, allowing specially constructed cars like the Superformance Grand Sport to receive CARB certification.
