All very true.
The good ol' boys at NASCAR turn their 358 cu in pushrod V8s to 9300 rpm on the big ovals. With a 3.35 (85.1mm) inch stroke they create piston speeds around 5200 fpm, higher than that of F1.
And they crank them at 8000-9000 rpm for hours on end (ever sit and watch an entire NASCAR race? I can't say I've ever made it through one). They are designed to last a little over 800 miles
