The S&S 520 cam is a great choice if you want to add some serious torque and throttle response to your Evo engine without having to do a full rebuild.

The 520 Cam from S&S Cycle gives my Evolution engine better throttle response and more torque down low without hurting reliability, though shipping was slow. For the price, this cam adds noticeable power and seems well-made from my experience so far.

The S&S cam provides a nice bump in midrange power and acceleration compared to the stock cam. After installing the cam, I noticed stronger torque and acceleration right away.

Wow, the new 520 Cam from S&S Cams is just amazing, I’m thrilled they tested it extensively before selling it, the limitations are no big deal for an enthusiast like me, and their customer service resolved my issues promptly, this cam is better than the competition as long as your motor is the right size.
