65 chevy 250 engine question

[kblake53]

New member with a couple of engine questions.
I recently bought a 65 chevy truck like the one I had back in the 70's.
It had a slight engine miss when I bought it and I thought I could tune it out. As it turns out I believe it has some worn down cam lobes from what I mearsured on the cam lifts. From the cassing numbers the engine is from the 66-72 time frame and I would like to keep it and get someone to rebuilt (long block) it.
It's a chevy 6 cylinder inline 250 engine.
Questions:
1. What should I expect this to cost?
2. Were could I find a new replacement oil pan?
3. Is having it shipped to an out of state builder a good option????
4. Any tips are very much appreciated.

Thanks,
