I think there is a huge difference between a 4 banger and a big block spinning well over 3 grand for hours at a time.





Yes and no

Smaller engines usually have shorter strokes which is conducive to high rpm cruising. But, 3000 rpm is 3000 rpm... The piston sweeps the bore just as many times regardless of the bore/stroke, and rings/pistons sweeping up and down is what adds to engine wear.



Again, yes and no. With the smaller bores and stroke, there's less moving mass that doesn't move as far and that allows the engine to have a higher natural frequency (otherwise known as red line). But I don't really see a difference from a wear standpoint. Also, 4 bangers need to spin at a higher rpm at higher speeds in order to keep the car moving. It's actually a little wasteful for a v8 to be cruising at 3000 rpms (all depending on the vehicle's weight and aerodynamics).
