I've got a 2008 FLHX with AC, Rinehart true duals and race tuner. Want to go with some cams. Not sure I want to do much else at this time. Anyway, my dealer seems to like either SE or S&S cams. What would be the best for low end torque with the above options. What about other manufacturers if I can talk them into using them? Probably stick with chain drive. Thanks.
