Body: Corvette Grand Sports are being built true to the original body shape and configuration. All new precise modern production molds have been produced to assure consistent and correct bodies. Chassis: Superformance built street cars feature the original Grand Sport round tube style frame. Modern Comforts: Superformance Street cars have power brakes, power windows and locks with all the amenities you would need in a modern high performance automobile. Trade name and badges: The trademarks for the 1963 Grand Sport body and the Corvette name, logo and badges belong to General Motors, and Superformance and Duntov have been granted permission to use them in an exclusive license agreement. This adds value and authenticity to your purchase. Engine recommendations: Engines are available from GM retail outlets or Duntov Motor Company. The closest thing to an original 1963 spec Grand Sport engine would be a 377 cu. in. aluminum small block with Weber carburetors. You might prefer a modern LS7, or one of the historic GM aluminum 427 big blocks. From Mild to Wild GM have an engine for you! Check back for updated news........
