Fred - He's wrong. If two different engines have identical power and torque curves they will run exactly the same in the same car, PERIOD!!!! (as long as the engines weigh the same) Matters not if it's a Honda or a Hemi, high or low tech.
There is however intangables that make all the difference. Starting with costs, there is also durability factors, how a engine throttles up and down under load, V.E. factors that affect mileage, and how different engines react to heat to mention a few, and many, many other things.
In the real world it's these other intangables that dictate the choices we make with engines, or cars for that matter, or even toasters, blenders and t.v's.
Good luck with that 383,,,,,,,,,,,,,,,,,,
