I read on another thread here, that someone who was running 3.31 final drives loved them. His only complaint was it was a little difficult trying to idle through parking lots and heavy traffic. I am going to run the CR toploader in the new car when it arrives, but I have decided to go with the 3.54 final drive. I don't feel I need a top end greater than 160 mph!

A decent 427 - not the worst, not the best, will go from zero to 100 mph and back down again to zero in less than 14 seconds. All thing considered, you can put together a pretty good argument that the 427 Cobra is the ultimate performance car, judged on any basis you want to name."
