Need advice on 1st engine build - cam bearing damage

I guess something else I should add is that this is just supposed to be a temporary engine of sorts. I was a little surprised to see how much it costs to convert one of these cars from /6 to V8. All new exhaust, all new cooling system, new fuel system, new trans. My plan is to (at first anyway) put in a fairly mild V8 so I can keep the 7 1/4 rear and 14" wheels/tires I'm running for the time being. Then I'll upgrade the rear, wheels, and trans as a next step. Putting in a stroker will come last. That's why I don't want to go crazy with dumping money into this engine, so I'm hoping to reuse as much as possible, like the stock cam.

Here's a picture of the crank. I can't catch a nail on anything, but I haven't mic'd it yet.
