The following cams came on my evo x, they have a k stamped with a green stripe on the side can someone tell me what ones these may be...... kelfords?

 

This screams for a picture.

 

Absent a picture, I vote they are K-Mart cams of limited manufacture, made entirely of ABS plastic and from the Cindy Crawford design catalog. Walmart has since bought the build rights. You sir, have something special, don't take them over 2150 rpm.

 

Totally disagree. I believe that the K is for K-tel, the infamous, as-seen-on-TV seller of compilation records. Here's a link to the best song they ever sold: K-tel's best song
