'69 340 Questions

Com'on guys, It's going way off track. Lets stay on target :elmer:
The question was not about selling it, whether it was a good buy, or how to do make power on a fixed budget like Lemons race or Grassroots challenge.

Yes. Open it up. Check condition, and also a measure the distance in the hole or out of the pistons and CC the heads.
For a long lasting street engine, a 340 cam is decent choice.
Also see if the heads were ported. Someone putting a high lift cam in may have done some porting. If there isn't, even less point in going with cam lift resulting in something over .5"
