| TORQUE-MASTER HYDRAULIC SERIES |
|
.842" minimum tappet diameter required |
| The Torque-Master Hydraulic Series is our most popular hydraulic profile series. They are versatile cam profiles that can be used for towing applications in the lower duration profile ranges and the higher duration lobes can be used as street performance, drag racing and oval track cams. This series is known for creating added torque throughout the RPM range. |

| BH HYDRAULIC SERIES |
|
.842" minimum tappet diameter required |
| The BH Hydraulic Series was designed to accommodate track rules where a .425" lift limit rule is placed. These profiles have very fast openings and work very well where the lift rule is an issue. Although the .425" lift is figured with a 1.5:1 rocker ratio, these profiles work well on Ford applications where valve lift is not limited. |
