The 112 is the LSA... lobe separation angle. There is normally another number after that for ICL which for these cams would typically be 108-ish, but that number is missing here.
I have the card that came with the cam i will dig it out and try to find the icl number. I am in southwest va
That last (missing) number is the ICL as the cam grinder grinds the cam relative to the standard sprockets and keys on cam and crank. A 108 ICL number would indicate that the cam is advanced 4 degrees if you installed it dot-to-dot. (112-108 = 4 degrees advance). So if you install it at ICL=104, then that is 4 more degrees advanced from the dot-to-dot installation, which would be at the +4 position for the crank sprocket of one of those settable cam timing chain sets.
BTW, where are you in VA?
