Over revving is not good for it, and.......
Some people are also of the opinion that excessive lugging of an engine
is not good for it. If you are lugging it to get better gas mileage,
I install 4" Vacuum Gauges, (looks like a Tach) so people can featherfoot it away from the red lights, without lugging it.....and also so they
can featherfoot it instead of flooring the gas..... -Bob
