There seems to be so much controversy on lift and duration of this cam. They say a 318 mag cam is a little hotter than a 360 mag cam, but this is the LA 360 version. I can tell you this, though, that the LA has a 1.5 rocker ratio, and the magnum 1.6. This means whatever the lift is, I will gain approx. .030 more lift due to the rocker ratio.
