I may owe madmaxx an apology if he was referring to a small block and a big block of the same displacement. I took it that he was comparing a much smaller engine to a much larger engine.

As for rotating weights, momentums, inertias, etc., I think you guys are putting too much thought and concern into it.

Your typical 427SBF is based on a 4.125" x 4.000" combination. Your 428FE is based on a 4.130" x 3.980" combo. Essentially the same specs. Yes, the FE rotating assembly might weigh a little more, but when it comes down to it guys, both are going to make a buttload of power/torque and it will come down to traction and driver ability to see which car would cross the finish line first.
