i recently bought a tore down 03 400ex from my dads friend from work. its a rolling chassis and a box of motor parts. all it has towards motor is just top end with no gear box or bottom end. But what i was wondering was that on the cylinder head, where it typically says 397 cm (im thinking) this one says 432 cm, and it looks like its been grinded down and cut into it.... do you think that this motor is a 440 or bored out or something because of this? How could i tell if it was. thanks...
