These 286/300 tight lash flat tappet cams are specifically designed for use in 305 c.i. sprint car classes.

Lifters

With the increased rpm, additional spring pressure and aggressive cam designs of today’s performance engines, premature cam wear is a major problem. COMP Cams has answered the challenge with the new Oil Injection solid mechanical lifters that feature a precision 0.012” oil feed hole in the cam face. The added oiling capacity creates a boundary layer that protects both the lifter and cam lobe from excessive wear.  

COMP Cams lifters are manufactured to the highest standards and when used with their oil additive, will give you the best results.
