I know that for all fbodies, the limiter is 162mph, unless they come with the non z-rated tires. I would imagine the drag limit on all the LS1 fbodies is pretty similar. What I am trying to find out is the name of the magazine or article that had a Firehawk in particular doing flatout 171mph using instrumention other than the speedo around a top speed track. There was also a Lightning involved in this, if that jogs anyone's memory.
