SOLID FLAT TAPPET<br />
JF .330" LIFT SOLIDS<br />
The JF .330" Lift Solids are designed for use in lift rule classes that require higher rpm or lighter springs than<br />
needed with the Max Area Lift Rule Series. The JF designs are also good for use with very high rockers in more<br />
open applications. Can also be run in hydraulic lifter applications.<br />

MAX AREA (MA) SOLIDS<br />
The Max Area Series is designed for 2-barrel and stock intake applications, which are airflow limited. This series of<br />
lobes utilizes low seat timing with maximum area under the curve. These lobes perform best with a 1.7 or 1.8<br />
rocker ratio and can be used with an .842” lifter. Note: <strong>Cam</strong>s using these lobes should have provisions for<br />
increased oiling. Please consult with our tech representative.<br />
