If, for the sake of discussion, one were to claim that the 3.0L OHV is more reliable than the 4.0L OHV, then IMO it would have to be because over the years the 4.0L has been somewhat more prone to (1) failed intake gaskets and (2) cracked heads, than the Vulcan has been.
On the other hand, though, the 4.0L Cologne doesn't have nearly the reputation for failed camshaft sensors & synchronizers that the Vulcan does. The 3.0L synchro shaft failures are even known to occasionally cause the oil pump drive shaft to stop spinning, cutting off oil flow and seizing the motor.
