ENGLE CAM – FK-7
The Engle FK7 is a classic VW Cam for milder engines. It is designed for 1.4-1.5 rockers, and it’s specs are .357″ Cam Lift, .500″ Valve Lift (1.4 Rockers) 288 degrees of advertised duration, and 244 degrees of duration at .050″, on a 108 Lobe Center. This is a much milder behaving cam than many people think it is, because it lifts .500″. If you want a lopey idle, get the FK8 or bigger!This is a good cam for engines up to 5k RPM max, it will idle like a stock engine with dual 2bbl carburetors, but will idle a little rougher with dual 1bbls. This is a great cam for someone that is not going to rev over 5500 RPMs (yes we know it will go higher, but the power is already falling off rapidly so there’s little point), and has some head work to support .500″ lift. Especially since lifting .500″ with 1.1s or 1.25s is hard on parts!
For reference this is like an Engle 110 for Ratio Rockers. It has mild ramps so it’s quiet and you can get over 100k miles of engine life from this cam. Dual springs are REQUIRED. Works best with Compression from 8-8.5:1.
