[GTO-relic]

I have this solid mechanical lifter cam, have a rough idea what it is, but not exactly.
box says:
Crane CC-290
with Crane part # 284691
(see pic attached below)
cam is stamped CC-290 on front face as well.
does anyone have an old Crane catalog that has it listed ?
I've found listings for BBC, SBC using the -4691 suffix, but they differ for every engine.
It's a used cam. I can measure .313" intake lobe lift, .329" exhaust lobe lift,
that would be .470" intake lift, .494" exhaust lift, with zero lash.
I'm assuming it's 290 degrees duration seat to seat, but may be slightly more.
it has a little wear on it, on the tips of lobes. but not a lot. good usable cam yet.
please post if you can, thanks.
