I have ported a 395, a portrd 390, and two portrd 372's. I use the 372's with 28" bars the most, by far, but they pull and oil a 36" respectfully.
I'm not that fond of the ported 390. Basically it's a lot heavier, less nimble, 372 with more grunt, however it does not cut faster for me at all.
The 395 even stock pulls like an old 6 cube 100cc saw with all the speed of a 372. After getting it ported, it pulls a long 50" + bar so well I sold my ported 880 & 088. If it will oil it, it has the grunt to pull a 72" bar, no doubt. The ported 395 will cut with a ported 120cc saw all while weighing 5 lbs less. It's as strong, dare I say, as a Mac 125, but with a ton more speed. Make of this what you will. But a 395 is in a class of its own period.
