Likely an OEM cam of some sort. Most aftermarket cams are marked differently.

Unless it's new, or you kept the lifters for it in order, it's junk anyway.

This is what I dug up doing a 3 minute google search:

Intake Lift = .390
Exhaust Lift = .410
Intake Duration = 310
Exhaust Duration = 320
LSA = 114
Rocker Ratio = 1.50
RPM Range: 2200-5200
Hydraulic Lifter

Part Number = 3896929
Casting Number = 3896930

Basically, like Cobalt said... It's junk.
