Looks to be pretty much stock, I restored a 73 a couple years ago for someone. It had sat a very long time and not long after I got it running something let go in the engine and it locked up. He didn't want to spend any more on it so I never figured out what it was.

I learned all I need to know about life by killing smart people and eating their brains.
