A few things we will need to address your concern about your engine being the original:

Is the engine a 6 cylinder, V8 ?

V8 Casting number, normally found on the block behind the cylinder head on drivers side

Casting date, this is the date the block was made...it would be something like D 17 2

V8 - on the passenger side....front of engine there is a pad with the VIN stamped along with the actual date the engine was assembled...also, there would be a suffix after the date.

Take some pics, post them and we all can provide our expertise to answer the question.
