I walked into a shop one time, about half an hour after a guy "popped" a Rat Roaster on a Hemi. He said "What?" a lot for another hour. Then there's the story Allyn Lee has told me, a few times, about how he wrecked an intake AND the hood on their 68 car at the Winters. He said it was a toss up if that scared him worse than the time they cut down the bump stops on the control arms only to find it makes the car really spooky when you drop the nose at a buck-forty.
