Crane cam #.

crane, 198131, Mech. Roller, 4200-7500, 0.608, 0.608, 268º, 268º, 300º, 300º, 106º, Competition only, good mid and upper RPM torque and HP, oval track,

Not familiar with 198121 but I know they made a 580 lift roller that was 262 duration @ .050. Maybe your numbers aren't clear. There should be some other numbers like RFOR***/r8. The grind number.
