I'm practicing porting a 365 cylinder and are planing on using these numbers, ex 100, trans 120 and intake 80. Would those numbers be good running a short bar? Suggestions from anyone with experience porting the 365 would be appreciated.

I should add that I've already widen the exhaust to 68% of the bore and set it at 100. I've also cut the base for .020 squish, removed the skirt at the transfers and gasket matched them.
18"to 20"
I just looked in my black book of port size differance and exaust I have done and dyno mite numbers you will be satisfied with these as long as you advance timing 2° on keyway it's a easy process and put the muffler mod with gutted can in this configuration like I did on a 575 you will be more then ahead the game and have a saw that makes u smile ear to ear run 40:1 either Lucas or royal purple two stroke synthetic also make the exaust ports as flat as possible and intake for less spit back rebound loss also mine loved a hotter plug one number hotter if I can remember correct it was a odd plug hard to find been a while since I built and sold those saws keep a post on your progression

That's good to hear, thanks. I'm going to advance the timing little by little and see what it likes best.
I already have a muffler I made for another saw and didn't use, but thanks for the suggestion.Like this it does put exaust back In operator area at times and can burn extreme dry wood i never had problems or exc
