All right---things have changed, only a few items remain the same and a couple of them are constants, time, distance, gravity

A long time ago to put some things into a perseptive that a person could understand---1320 ft---time 6 seconds---rpm average of 10,000

Engine in 6 seconds 1/10 of minute would turn over only 1000 revolution , each spark plug would fire only 500 times---- a fuel burn of 6 gallons equalled 60 gallon per minute or 3600 gallons per hour or about the same as one/half of a tanker truck at a rate about egual to how fast the tanker could unload at a gas station!!!The time was early 70s and 6 seconds was a medium et and was more easily understood as you could just move decimal points for calculations.
