Yes, and yes -- they are not too big, nor is the engine compartment too small. The heat is readily dissipated with the proper radiator, fan, and shroud combination. That said, higher horsepower FEs do tend to produce more heat than lower horsepower FEs -- but really, on the street, there's not much difference between 475HP and 575HP because you can't use either safely for more than a couple of seconds, if that.
