I don't understand but admit no first hand experience with the 583 in a 110". By the specs it looks to be challenged to run at anywhere close to 10:1 with the 203° degrees intake duration and intake closing of 18° ATDC. The only experience I have had with the 583 is guys pulling them when they realize they are not related and in between the 570 and 585 and their bikes ran poorly because they set them up at 10:1 and expected more. S&S has an interesting line of cams and with some understanding some can work well but I would say the same about the Screaming Eagle cams.
we`ve had very good results with them in touring builds.set them at 9.8-1 and they make very nice power down low,but carry a bit higher than the .551 or 255.if guys are installing them thinking they will be a "in between" cam for the 570 to 585,i can see why they`de be disappointed,completly different profile
