You can find the old Ultradyne online cam catalog on the
internet archive site.

Many of the ultradyne grinds are also shiwn on the Lunati cams site as "New street strip". etc.
Bullet can make you a ultradyne cam.
measure the in and ex cam lobe lift.
The LSA is 110.
I'll take a stab at it and say
the intake lobe is #F12. ex is lobe #F13
You can find these on the Bullet/ Ultradyne cam lobe masterlist
