Guys with Crane Cams Book- Need Help

Crane #99835:
- 1.5" OD, 1.086 ID, has damper; Seat 113 @ 1.600". Open pressure 280 @ 1.15". Coil bind 1.000"". Rate 412 lb/in. Max net lift 0.565".

That is very high spring pressure for that size FT cam, not good for lobe/lifter life.
Might want to look at the Crower #68404.
