Pro stock engines sound so clean, they will rev 10,000+ and then drop back to an idle of 1100-1200 rpm. They are sweet close up in person. Many years ago, it was mentioned that Warren Johnson ( called the professor of pro stock ) would spend $ 400,000 on valve springs in a season. The engines go round after round with no real maintenance, other than to pull the valve covers and check the valve springs. Any dead springs are changed out, the covers are re-installed and out it goes again.
With the amount of energy they dissipate at those engine speeds, they glow red hot during a pass, despite having oilers spraying pressurized oil on them under the covers. The pushrods look more like telephone poles, they are 1/2 - 9/16" O.D. and .200 inch thick.
