RC (Russ Collins) Engineering Cam specs?

I've attached a jpeg of the RC catalog page with cam specs . . .

Got the Russ Collins catalog today. It appears I have the Stage III package on my 1000, which means bored to 1176, not 1173. I feel like a better man . . .

The RC515 Pro Stock Special cam:

Total duration: 310 degrees

Lobe centers: 108 degrees

Lift: .424 in. intake; 424 in. exhaust

Lash: .004 in. intake; .006 in. exhaust.

Thanks! I don't see your scan image, but that's the info I was looking for. Too lumpy for me, I'm afraid.

Oh, if someone wants the RC515s, I can put you in touch with the seller. He was asking for offers.
