340 camshaft question, yea another one.

Now I must be going crazy.
I am sure the original 69up 340 cam was a 268. How sloooow would the ramps be,for it to net 208 @050? Surely not (268-208)/2=30* per end. That's crazy slooooow, isn't it?
Most Mopar performance cams I have seen are in the low to mid 20s per end.
Shoot, I thought the 360 2bbl cam was bigger than that...............


The mopar cam should be around 228° @ .050" on the 268 lobe....
