340 Timing / CAM Issue

Thanks for all the info. Very helpful.
Today I pulled the intake and found 3 not-so-nice surprises...
1. The cam is wasted. Must not have been lubricated properly on startup. One of the lobes looks like someone took a grinder to it.
2. There is a significant chip in the manifold between cylinders. You can see on the gasket where it didn't seal.
3. This is the worst...I NEED YOUR OPINIONS on this. The block has been repaired with some type of epoxy.
Obviously i need a new cam and intake BUT, is the 340 block worth putting money into it or should I get another engine? It is a 73 340 block bored .30 over.

Hopefully photos loaded.
