462 is 72 cc. My 460 and the 461 are 77cc which evolved into the 462. They discontinued the 441 which was 70cc if im not mistaken. My 460 mostly wears the 28" bar. Came with two 20" chains so i got a 20" bar as well. Also bought a 36" bar thats fun to use on the rare occasion i need it.. Talk about feeling like a professional lumberjack! Ill run the 361 with the Carlton bar for now. Had considered a 25" for it. I go back and forth about porting my 261 (50cc pro saw). Member here wants $380 inc shipping. Several FHC members have said to do it.
