LS6 454 teardown - need help identifying cam

[dhardison]

Tonight I started tearing down my old 454, mainly to get ready for a rebuild, but also to finally find out what's inside. I'm unable to determine the cam model/brand also whether it's a hydraulic or flat tappet cam. Any help would be appreciated. Some numbers on the cam were:
15 48 - cast markings
CWC I5 - cast markings
3143 - stamped in to rear of cam

Here are some pics of the cam lifters:

From all the casting numbers I was able to tell that it's a LS6 block, with 11.25:1 forged pistons and 118cc, rectangular port, open-chamber heads. Some more pics:
