Question about putting a yz450 motor in YZ Laeger Frame??

[310r]

I am wondering if it is even possible to put a yz450 dirtbike motor in my yz laeger frame? How much of a difference is their going from the 426 to the 450? If it is possible to fit the 450 motor, then what has to be done?? Any help with this would be appreciated. Thanks guys

very mininal difference, the motor and most stuff should bolt up.
