Well, if you compare two different displacements, bores, strokes, etc., then it's really not a valid comparison. A 482ci FE has a longer stroke, larger bore, etc., than a 427SBF and it will also make a higher average horsepower/torque that you could feel across the whole curve.
As for even displacements across engine families, if they make the same horsepower and torque, I honestly don't think there would be enough difference between them to say that one car would walk off and leave the other because of rotating assembly weight.
Rod, Google "buttload".
