I found this cam on the online NAPA page. I believe this is the stock or real close to the stock 188/188 cam.
NAPA part number They use to sell this 194/204 cam that I believe may be the same cam Whitney had. I scanned this from a printout I had fortunately saved..

I agree with DeuceCoupe that your rise and descent notation is a little hard to interpret.
When I dropped the engine with this cam back in my '67 3/4 GMC, I changed the 4.56 gears for 3.54 and it seemed to wake up and pull harder. Pulls strongest from 1500 to 2800.
