More power for my 440e mark2

[Robert Small]

I was wondering if I can use the top end from a 445 or 450 on my 440e Mark II?

Not a Husqvarna expert , but I have owned a few including a 440, mine was old , I am going to say probably not , buy a 445 or a 450 if you want more , i loved my 440 for its nimble lightweight attributes of limbing and bucking smaller stuff , lugging it around in the mountains was a joy compared to my other saws and it was powerful enough for a 40 cc saw .
