Yes, well to me
my engine never sees the under side of 3200rpm, except when idling. Howmuch torque does it have at 7500 rpm? If it had that much then it would be making serious power... or is that when it goes bang, from such a long stroke and such heavy (but robust) engine componets.
Anyway as Tim said, they are great for just driving around slowly, give great fuel consumption if driven sedately. Diesel engines have loads of torque low down, but because of the long stroke required to get such high combustion pressures, their ability to revv is far less, due to being so far over square. The piston speed is too high.
They are also great, when designed to operate at a fixed speed, like generators.
Me personally, i love the feeling and sound of a engine going up to and past 7000 rpm
