New Corvette C8 Radiator Considered the best and cheapest modification for Camaro or Corvette C7 LT1 engines, providing excellent horsepower for the price, approximately 25-30 horsepower difference. The radiator comes with all its accessories, including gaskets, sensors, and wire extensions, meaning it's a complete A-Z project. Just remove and install, you won't need anything else. It's a standard and original GM system. What's special is that the radiator is ready and pre-drilled on the back and bottom as well, to save your time and mine.
