All I need to do now is change the name plate from MS310 to MS290 and go torment some 346's,LOL
Both those saws had new chains on them, you can see the 3/8 chain on the Stihl really pulls more chips more aggressive than the .325 on the 346...
When I saw you start this thread, I was sure hoping you'd put a 390 topend on it There's not much difference in price if I recall.
