LOL, now it getting absurd, 660, LOL, really, the guy cuts a little firewood, isn't likely to be a pro athlete, and therefore would cut more wood with a 70cc saw than with any 90cc saw given to him, due to the weight of the 660's, common sense here people. Hell I cut professionally, and have/had two modded 660's, they never get used, because there is zero increase in production for the effort of carrying a 90cc around and filling it up every 4th tree, cutting firewood would be an even worse showing for the 660, but you would have to have some wood cutting experience with both saws to know that kinda stuff, instead of letting your testicals get in the way of common sense, but this is a chainsaw forum so common sense isn't always to common, as there is always CAD to deal with, LOL.
I've got a modded 084 with a pretty good power to weight ratio, and I'd spank most anyone with a little 70cc saw cutting most anything with a 28" bar and less, what the heck does power to weight ratio have to do with cutting firewood if the saw weighs what a 660 does, thats just sure sign of lack of experience and ignorance to advise such a thing.
Do any of you even read the advice here by those with more saws and more experience???? Several "advisors" here actually have modded 660's, so there is way more power to be had with that choice than some little stock 460, yet the owners of those modded 660's that have modded 441's would rather run the modded 441 and know that they are going to cut more wood, than the modded 660, do you get it, we are way, way past the "traditional muscle" of a stock or modded 460 ......... whatever that is???? Traditional Muscle, LOL, the 441 M-Tronics has a much better powerband and fuel mileage, one operator here says a 441 is double the mileage and another is at a 2 to 3 ratio of the 460 (either way its pretty substantial), plus it has much better AV and air filtration, basically, as I have said many times the 460 wins cookie cutting competitions by seconds and loses real world cutting by minutes, therefore common sense would lead one to understand why a person could cut more with a 441, due to its several other benefits.
I just think its funny, how, praisers of the 460 love its suposively more powerful platform, yet you will not cut anymore wood with it, due to its, "traditional" poor fuel mileage, air filtration system and AV system, a comfortable operator will cut more, its just common sense ..................... plus the 460 costs a lot more than a 441 with all the bells and whistles, I've broken 460 mounts, I've never broken a 441 mount, ever and I'm hard on them when they get pinched.
My opinion and experience, have fun with that,
Sam
