Forgot I had a few more pictures on my phone.
I tried to get some shots of the cam where it broke.
This one is a shot of a lifter on its side wedged between a cam lobe and the block.
Here's the very rear part of the cam. You can see the "core" of the cam. It's the lighter gray. The cam lobe has the black on it next to the "core". You can also see that busted lifter above it and one that is still in one piece and in its bore below it in the pic.
Here's a shot of the other side of the cam where it broke. It looks like it broke flush with the cam bearing journal. Again you can see the light gray of the "core" and then the darker color is the part resting in the journal.
So maybe it's missing closer to 3" of cam. The width of two rods and a crank counterweight.
