Dumbest newbie thing,you did at the drag strip.....

We had a cable drive rev limiter. (Early 70's) I had it off and working on it and when i put it back on, didn't notice the cable slipped out. Well you can guess the rest. Driver usually left with a popping of the limiter, but this time he left with a rod thru the block and 9 quarts of pennzoil on the track. Dont remember the time but he went all the way to the end. ET was slow by 2 or 3 seconds. Took an hour to clean up at Rockingham, N C. Worst part was had to be in San Francisco racing the next week end but that week is a long story.
