Need help identifying camshaft etching

[TruckManiaMike]

Just bought a freshly built motor but the guy didn’t know what cam is in it. Here’s what I made of the hand etchings
BC
298/298
F7
T15707

If anybody has any info it would be greatly appreciated!!

On a 440 big block

sorry no idea,
numbers seem familiar,
but I looked & nowhere near the same I was thinking
in an old Lunati cam
solid flat tappit advertised' 298*/0.570" gross valve lift,

The guy thought it was a racer brown cam. He said he bought the short block built from a builder in Detroit.

Just a guess.
F= flat tappet [ solid lifter ]
7 = 107 LSA
298/298 adv duration.
