A few years back we took the Comet up to the chassis dyno shop in Watertown.... The car had sat the winter in my old shop out on the farm, brought it to town and put the freshened engine back in it. Engine had been on the engine dyno for run in and a few pulls before putting it in the car, so no reason to do anything but commence with the power pulls on the chassis dyno!!!!!! Headers were big tubes with 4 into 2 into 1 collectors and a booger to pull, so we always unbolted them from the heads and left them in the car for the winter... On the first pull, a giant glob of nest material came out the collectors!!!! Rodney and I spent about 2 hours cleaning up Andy's Dyno and shop!!!!!
