lennyj, I have had some experience with the 585 cam. When I had my 95 Heritage I put an S&S 107 in it, and a 6 speed trans with a 31 tooth front pulley. My 107" came with the 585 cam and the smaller of the two S&S carbs, I think it was the Super G. It also had their IST ignition so I got a 3 year unlimited mileage warranty. No dyno needed. Great power from idle to top end although I don't think I ever saw the end of 5th gear. It is a great cam for your bike. Probably would be a little soft on the bottom end if it were installed in a bagger which weighs in at over 900 lbs. My friend also had one in his 2003 Dyna which he had punched out to 103 Cubes. His bike was light and ran great. Also on my Heritage I was just using SE mufflers with the crossover tube. They came off a 2002, but bolted directly on my 95 Heritage.( wish I wouldn't have sold it ) Congrats on your great tune. CAHDBIKER
