It is in this case. If you set out to build a 440 inch COMP engine you would use a different cam, manifold and port design to name a few changes. But for B/A with a 500 incher, the car would need to weigh over 2700 lbs. Larry has plenty of "old" stuff laying around so he orders a short stroke crank and builds a 440 for a 2370lb B/A
