I have been seeing several 54 Corvettes being sold on line, some by big classic car dealers. They all keep saying orginal condition yet one even had a Chevrolet 350 small block in it. Is there any way of telling just how many of the near 5,000 cars actually survived? I don't recall ever seeing a 53-55 ever, only in pictures and I have been to a lot of car shows. I also noticed most of the car's that appear on video have a roaring exhaust sound. Were the mufflers on 53 -55 different then the Chevrolet passanger cars?
