I have a print out of both Crane & CD lobes which I believe is complete.
- R284. 338 adv @ 003; 284 @ 050; 191 @ 200; 0.308" lobe lift. Stocker series, dwell at max lift. This is a hyd roller.
- R286/500. 326 adv @ 0.0162"; 286 @ 050; 200 @ .200"; 500 lobe lift; lash 0.026".
- R296/4778-10. 328 adv @ 0.0225"; 296 @ 050; 209* @ 200; 0.4778" lobe lift; lash 0.028"; 110 LSA.
Good lesson to learned from these old profiles. A lot of nonsense from cam companies & a particular cam grinder who posts on another website. Listening to him you would he has invented many new designs.
Here, amongst these decades old lobes are sym & asym lobes, pages of Inverse Radius lobes, constant dwell, 0.640" lobe lifts, low harmonic lobes for increased valve spring life in circle track, etc.
