.550 is 249, .600 is 263, .650 is 267, .700 is 269. These are the entry level B1 small block heads. With porting the BAs will give the 300 numbers at .600 lift. But the real magic is the potential in the MC heads, and the chamber design which is fatr better than Edelbrocks.
I've run that same Crane cam. Crane is one of my favorites. That one's a great piece but it's still peaky and it's hydraulic which means more spring needed and less rpms because of the plunger. Depending on the piston and quench you might want to go a little bigger. I'd run a flat tappet in the 250-255 @ .050 and around .580 after lash. Simple, effective, almost bullet proof, and cheap. If you want more steam I'd bush the lifter bores and run a solid street roller with a little less duration at .050 and a little less lift. Something that will be easy on the springs.
