Installing Custom Roller Cam per FABO reccomendations

you are better off with a slow .904 lifter profile than a fast .842
are you looking at the online catalog
for comp you have to look at the so called jeep profiles- there are all 4 of them
remember crane advertised duration is at .004 and comp is at .006 so an identical crane using crane method shows longer duration- sometimes a lot on a slow lobe
unfortunately Hughes does not give seat timing
Cranes profiles date from the earlier valve spring era and do not pushthe envelope
they are smooth- Like Engles the .904 will have more area under the curve- it does not try for maximum lift which would take different springs
