Talked my buddy into an 8 pin sprocket and a 20 inch oregon bar and chain setup. He was running a 36 inch bar setup before. It's a screamer now. I'll get video of us running it next time we cut...
My 460 was quicker in a cut than my 660 both with 18" bars and 8 pin sprockets. Big bore 660 vs woods port and dual port muffler 460.
