Got the cam degreed. I checked it at a lot of different points to get a good picture of the lobe profiles.
The dial indicator we have for degreeing the cam has a .750" ball on it. The roller wheel on the lifter is only .710" or so. Because of this, the cam checks 4° bigger than it really is. I have confirmed this before by degreeing with this, and re-checking with the actual lifter, and a dial indicator on it, which is much harder to do, so I use this setup, and degree by the ICL method, rather than opening and closing points. I wanted this cam installed at a 104° intake centerline. Using the "0" marks on the crank gear, it came out at 105.25°. I used the +2° key, and what do you know, it moved it exactly 2° to 103.25°[I've seen these 2° keyways change the timing anywhere from only .5°, to 1°, to 2°. You just never know what they will do until you check them]. I settled for this as it will loosen up some. I have found before that these cams like to be 6°-7° advanced anyway. Installed here, the intake lifter has .034" more rise than the exhaust at TDC, during overlap. I find these cams like this number to be .035"-.040", so it's pretty much perfect here. When it was installed at 105.25°, there was only a .020" difference. Just not enough.

All in all, here is what I found out about this cam[using the .750 ball on the dial indicator]:

It has 287°/294.5° duration @ .006" lift.
It has 235°/243° duration @ .050" lift.
It has 211°/212.5° duration @ .100" lift.
It has 157°/165° duration @ .200" lift.
It has 95°/105.5° duration @ .300" lift.
It has .357"/.366" lobe lift.
At TDC the intake valve is open .162" with 1.65 rockers, and exhaust valve is open .106" with 1.65 rocker, when installed at 103.25° ICL.
Intake opens 14° before TDC, and closes at 40.5° ABDC, @ .050" lift.
Exhaust opens 58° BBDC, and closes at 5° ATDC, @ .050" lift.

Here is side one of the cam card with my notes on it.



Here is side two.



By studying the notes on side two, you can get an idea of what the lobe is doing.
If we look at the exhaust lobe for example[footnotes on upper right]you can see that from .006" to .050" lift, it took 24° of movement to go .044" of lift.
From .050"-.100" lift, it only took 15° of movement to get .050" worth of lift.[It's getting faster]
From .100" -.200" lift it only took 24° of movement to lift the lifter another .100".[getting even faster].
From .200"-.300" lift it 30° of movement to lift another .100". [Starting to slow down, and hold the valve open].
From .300", to full lift of .366", then back to .300" it took 105.5° of movement to move the lifter .132".[Holding the valve open for a long time]
From .300"-.200" on the closing side, it takes 29.5° of movement to get .100" lifter movement.[Continuing to hang the valve open for lots of high lift area].
From .200"-.100" it took 23.5°.[Starting to speed back up a little].
From .100"-.050" it took 15.5° of movement.[slowing back down now].
From .050"-.006" lift, it took 27.5° of movement.[Really slowing down now]
From .006" to fully closed it took 26.5° of movement.{setting the valve down nice and easy for a quiet valve train, and easy on the valve train also.
