The Engle FK-89 is a racing cam intended for large engines with lots of head work. It is intended to be used with high ratio rockers only. A very good cam for top end performance. It has been used for decades as a standard drag racing staple. Lift with 1.4 rockers would be .582″. We recommend using genuine Engle lifters with this camshaft.
