Internally vs. externally balanced
Engine gurus -- what are the practical application differences between an externally balanced engine and an internally balanced one? For example, besides the bore and stroke, how much difference is there between a 390 and a 428? (Yes, I know -- 38 cu in....). The 428 is known for lots of torque, right? But I don't think of the 390 as a high horsepower (again, relative to the displacement), higher revving engine. BTW, I'm intentionally leaving the 427 out of the equation for this scenario...
What's the scoop?
