Engine measurements?

[rearlockup]

Hi! I'm new here; I don't currently own an FZ-07 but I'm strongly considering using an FZ-07 engine in another frame (I have some sort of weird obsession with engine swaps, even in my cars).  I really like twins & this seems like the one of the strongest current middleweight twins.  

Now before you beat me senseless for a silly idea, is there anyone who would be able to do me a huge favor and do a quick, rough (+/- 5mm OK) measurement on the width of the engine between the head mounts?  I'll probably have to fab up rear mounts but knowing the front mounting width helps greatly with identifying frame options!
