B"H The coffee cup on the engine story reminds me of a recent video on Jay Leno's Garage web site. His Chrysler Turbine Car engine idles at 22,000 RPM. A glass of water on top of the engine housing doesn't vibrate a bit. I doubt if any 1963 piston car could match that for smoothness!! Bill Hershkowitz 69 Monza 110 PG
