09 Motor in 08 frame?

[Tim Kington]

I guess the title speaks for itself .. destroyed the motor in my 08 YZ450F, so am tossing up between fixing the old motor ( going to need new bottom end, and complete replacement of top end) or just getting a new motor .. havent found an 08 motor yet, but have found an 09 motor

was just curious as to whether the 09 will fit the 08 frame?

'06 - '09 are interchangeable
