4-71 detroit engine?

Looking at a 4-71 engine, and somebody mentioned that early models are not worth near what late model engines are that there would be different parts associated with each. So this got me to wondering - the only number that I can find is on the block, and is 5183376, and that is cast into it. I Have been search the web, but I have found no info on this motor, so any advice is appreciated.

There is a pad with the serial number, and model number on it you want to find that.
They are a very tough engine and can be rebuild multiple times. You want to remove the valve cover, and see if it is a 2 valve or 4, also is it a dry block, there is also an earlier version called a low block.
With the casting number a Detroit parts department can tell you that.
