CCS is correct. 112-114 lobe seperation is what your looking for, but remember when talking to cam tech reps don't let them steer you toward the biggest cam you can get keep it a level lower.
I have a 388 blown sbc utilizing a cam with approximately 660 lift & 114 lobe sep.
My heads are set up to accept a larger cam but I kinda like the low maintenance of this cam shaft. I have not broken anythind and I don't have to pull my valve covers off every couple runs to check lash settings.
