When I first started looking at these cars seriously last fall I told one of the Cobra guys at our weekly get together I was looking at a 521ci/600 hp cobra. He asked me why I thought I needed that much power and other than making a joke there really wasn't any reason I could think of. He said stick to a small block and you will be much happier. The small block cars are much easier to drive in my opinion and he was right at 450 hp this car is no slouch. It does fly. Wife and I took it out after dinner for a spin around the block and got into it a bit in second. I pushes you back in the seat. In 30 degree weather our ride didn't last too long.
