This is worth mentioning again.
Lazy low revving, low(ish) compression engines will run forever.
The more tuned an engine is the more it needs maintenance and reduced life.
In the days before electronic engine management, it was important for a driver to remember that an engine could only survive a short period of time at various revs. I don't remember the exact numbers now, but it used to be you would get say 90 seconds at max revs, 10 minutes at 7k. ( I'll ask brother next time we're on the phone ).
The point was that the valve springs and valves could only live for a set time due to stress and wear. So you could 'blip' the red line a few times per stage, but do it all the time and you'd have no engine mid-rally ! Also, you knew to plan a rebuild if you spent a lot of time near peak revs
None of that with an equivalent powered V8 !!
Ferrari engine management records the engine revs and gears and they plan service and replacement based on those figures ( I know because my boss got rid of his after the first service and they basicly told him what he'd been doing almost every day for the previous 3 months !! ) THAT is what you should do with a highly-stressed engine.
Again, I'll bet it's a lot less stressed with bigger CCs and more pistons than a peak-tuned and blown I4 !!
