New to 340 so I have questions

Which leads to more questions. The car does sound healthy and looks well cared for. Nick is this a low mileage car with the original 340? I'm wondering if it has the original bottom end, cam and heads with a swapped intake and carb. Inquiring minds. :)

good question, I am still trying to figure that out too.
The odometer reads around 64k, but that still doesn't mean anything.
The heads are X heads, that's for sure, I spotted the X immediately.
I want to check the block, I was told to check it like a big block at the pan rail, but I can't get on the ground to check it because of my bad hip and knees, (Replaced) it's too painful and I can't get up.
I was told to check the casting number, but I can't seem to find it because of the header in the way.
