On most ported saws most power is about 1500 to 2000 rpm more than stock recommendations from what I have found running mine
I did pick up a 346 killer on eBay, though. $91 shipped. Need to look at piston options and see what's available .
lol I have a few saws I want ported but it takes money lol I have at least 2 of the ones I want ported Cfb asked me how many 046/460/461 I had and right now I have 6. 4 of them are ported one is new in box and the other needs rebuilt
I need to send a few of my saws to Kevin. Going to need another big saw to buck with while the 441 is gone.
