Wr400 to Wr426 Motor Swap

Long story short I seized the motor on my 98 wr400 and came across a good deal on a complete 2002 wr426 motor. My question is will the 426 motor easily drop into my 98 frame and if so what if any modifications need to be done? Such as newer carb, jetting, different spacers, etc.

bump ......................anyone?
