Date code: B256 (I cannot recall how the B and the 2 are translated, but the 56 is pretty clear)
B = February (Month)
2 = Day
So though I cannot be sure, I would bet that the engine is the original one.
I agree and thanks for clearing up the numbers question for me. At first it sounded to me like the engine and chassis numbers were exactly the same and that would be of interest. It's always nice to find a vehicle that's never been molested with all of it's original equipment still in place...makes it rare and special!
