2010 SEMA: 1963 Corvette Grand Sport Replica Featuring the New GMPP E-ROD LSA Crate Engine

Visitors to the 2010 SEMA show will see a replica of one of the most iconic sports cars ever made: The 1963 Corvette Grand Sport Coupe. Superformance LLC and Duntov Motors produce the GM Officially licensed recreation sports cars and the display model at SEMA features the new General Motors Performance Part’s E-ROD LSA crate engine package which packs 556 supercharged horsepower.

The E-ROD LSA brings a modern power plant to the classic Grand Sport Corvette. Complimented with other amenities including air condition and Tremec 6-speed manual transmission, the Corvette Grand Sport replica takes performance and comfort far beyond what Zora Arkus-Duntov and his team of engineers could ever have imagined in the early sixties.

“The Grand Sport Corvette is such an iconic vehicle, that it’s great to see Superformance bring back this classic as a kit car,” said Dr. Jamie Meyer, product integration manager for GM Performance Parts. “It offers the same styling and raw performance feeling as the original, and when outfitted with an E-ROD engine, the end consumer gets a much more modern ride. The performance of this car is amazing.”

Whereas the current Corvette touches the scales at around 3,300 lbs, the C2 Grand Sport replicas with the 556-hp LSA comes in at around 2,500 lbs, giving the car a power-to-weight ratio of only 4.5:1 – or, 1 horsepower for every 4.5 pounds of mass. That’s better than the Ferrari 599 GTO’s 5.3:1 ratio.

New 556 hp GMPP E-ROD LSA Crate Engine

The E-ROD LSA crate engine package will be available after first quarter of 2011. General Motors Performance Parts is currently negotiating with the California Air Resources Board (CARB) to allow the LSA to be used in pre-OBD-II vehicles (1995 and earlier) as well as for specially constructed vehicles like the Superformance Grand Sport in California.

Highlights of the Superformance SEMA Corvette Grand Sport Coupe include:

  • GMPP E-ROD LSA supercharged 6.2L engine rated at 556 hp and 551 lb-ft of torque
  • Tremec six-speed manual transmission
  • Custom rear axle housing, with Dana 3.36:1 gears
  • Ceramic-coated custom headers and side pipes
  • Four-wheel disc brake system, with four-piston calipers at all corners
  • Period-correct Grand Sport racing wheels
  • Exterior paint in Admiral Blue, with bright white stripes
  • GM gauge cluster with 200-mph speedometer
  • Leather-appointed seating.

In addition to the E-ROD LSA, two other E-Rod engines will be available from GM Perfomance Parts. The E-ROD 5.3L is the most affordable and is based durable workhorse engine in the Chevrolet Silverado. The E-ROD LS7 has the largest displacement of the E-ROD lineup and is rated at 505 hp like the one used in the Corvette Z06.
