Does anyone have the specs on a stock 305 cam

Does anyone have the specs on a stock 305 cam. I'd like to experiment with a few options on my dyno software.

The stock TBI cam is listed in the camshaft tech article on this website. Its at the bottom of the page, listed as the 87 305 cam. I think its like 179/192 , and .373" lift or so.

GM Roller cam P/N 10088155

LIFT: .350 .384

I know that in Desktop Dyno they want the opening and closing points. I'm (hopefully) about to have the stock cam out of the car and in my hands. Is there a relatively easy way to get those numbers? Might be useful for anyone who likes to play with Desktop Dyno around here.
