S&S 550 build
I just recently had my 2018 Street Glide Special built by a reputable shop, we did a 550 cam, 114” pistons / cylinders, I’m running a D&D Billet Cat. The bike literally has power at anytime that you wouldn’t believe, my numbers are 116 hp and 123 tq, the power curve is amazing and it’s useable power, you don’t need 120 CI if you know what parts you need

550c
Just built 2018 m8. Stage 3 se but used the s&s 550 c , pushrods, and springs instead of se . V&h short shots and extreem flow ac powervision tune . 127 hp and 124 lbs tq . Very impressed. The throttle response is crazy from 2800 rpm and up and anywhere past 3500 is just plain nasty . Idle is awesome very lumpy . Best sounding m8 cam I've heard so far . This cam wants to be riddin 3 g and up its deff not for luggers .
