Comp Cam Pro Magnum Rocker Arms - 02/01/10 04:54 PM
Anyone using the big block Comp Cam Pro Magnum rocker arms with a hyd roller cam? Their website about the pro mags has a statement that the arms are recommended for 350 open lbs of spring pressure or less. I would think a hyd roller cam around .560 lift would go beyond the open pressure of 350lbs. Strength of the arms should not be an issue since they are made of chromemoly steel.
Also have they changed the design of the rockers (#1321-16). The old rockers had a teapot curved arm design where the roller is located. Now the website picture has a more straight roller arm design and a more open area in the bridge location.
