I still cant figure if they all had .525 gross / .500 net lift or if some had .500 gross / .480 net lift but it makes little difference, 3-4hp on top maybe.
Could be that the early ones used .480 net lift as valve springs were still not that great in the early 1960s.
In either case, near as I can figure the .050 durations are
228-228
LSA is 114.0 to 114.5 for all, straight up or close to it ie zero advance.
The old crane 294 I think is an exact clone.
I like the Comp 270s at 224-224-110 and 4 advance, it sounds & idles just like the Ford cam, peaks a few 100 rpm lower, but pulls stronger in between.
Here is a good thread from Dennis:
