My only consideration would be rotating assy weight, for a drag motor you want to be able to build rpm quickly and accelerate. Pullers leave the line and are at max rpm the whole time, so the added inertia of a heavier rotating assy or flywheel will benefit them by giving them a little more distance before the sled can slow them down...think of the big farm tractors and their huge flywheels - that is for inertia.
Also durability over power to a certain extent - Wider seat widths to displace those high egt's on pull motors, narrower seat widths make more power but do not transfer heat from the valve to the seat as well.
