I never claimed the 7910 (or even a 7900) was 6.5HP. without going back and re-reading what I posted....it could have been a typo.
Again, I have been out of the saw market for ~8 years, so dont know what the EPA has done to the main stream pro saws.
But back then, a Dolmar 7900 was 6.3HP. A husky 372xp was 5.3.....at the same weight and for $100 more.
Huskys next jump was the 385xp which cost a few pounds and same power as 7900.
So the Dolmar was the sweet spot for power/weight/price.
But all in good fun. Im not hating on the 372xp. So dont take it seriously. I like saws in general. Just a preference for dolmar. And in the 65-80cc range....I think they have the best bang for the buck in terms of power and weight.
