Waking Up a Turd

Here are a couple of pics of the mystery cam. There are no numbers on it that i can see.
I also slipped it back into the block to take some more measurements. I had a helper the last time we were taking measurements, and i didnt realize she was not writing stuff down, So now i dont know how to find any valve open / closing events without reassembling everything.
I come up with: Its a split duration cam. But the numbers don't match any MP cam on the list i have.
I took the duration events at .050 at the cam, Maybe this was wrong, Maybe i should have used .033, so it would be duration at the valve? Im sure someone can let me know... These duration numbers seem small for how lumpy the engine idled.
Inlet exhaust
Lift (cam) .313 .322
Lift Valve .469 .483
duration @.50 224 232
installed center 107.5 115.5 btdc These were taken before we dissembled everything

I'm actively researching what i think will be a great combo, I will post it up for the groups input when i have my numbers to together. I'm relying heavily on the "Max Performance small block" book by Larry Shepard, and the recommendations by this group to select parts.
