One way to increase power is to increase lift. That’s what makes Elgin roller tipped steel rocker arms so popular. They’re one of the highest lift rockers you can get outside of racing. And, along with the lift, you also get a ball pivot roller tip to prevent valve stem and guide wear.

The rocker arm ratio is 1.6. If you were to install 1.6-ratio rocker arms, the valve lift would increase to .512 inches (.320 inches x 1.6 = .512 inches). The engine will respond as if a slightly larger lift cam had been installed. In essence, increasing the rocker arm ratio is an easy way to improve the performance of an existing cam.
