Camshaft characteristics?

I just picked up this cam from a friend who bought it a long time ago but never used it. New in the box. It is an SSI or Super Stock Industries Camshaft. Hydraulic flat tappet camshaft. What I am wanting to know since my looking at this cam spec card is a bit confusing, especially the numbers which I think stand for Intake and exhaust center lines being different. At least from my perception. Here is the cam spec card. Please help by enlightening me as to how the engine will behave...
