buying an engine, advice needed

[JohnC]

Hello all,
First time posting here.
I was a WRX owner untill now but came back to experience some RWD bliss.
I own a 1995 EU spec s14 (200sx as it is know here). The car
has an sr20det, AT, LSD. not staying AT 4 long.
The engine is OK and was overhauld a few months b4 I bought it but the guy that did the work, well I don't trust his work at all. There is the chain rattle, compression is OK but I do not feel good about the engine.
Now for my question.
The dealership here has a NEW, yes NEW, complete longblock including sensors
pumps etc... and for a VERY good price.
The only dilema I have is this:
The engine has been sitting in the warehouse for the past 9 years.
Should I be wooried about buying an engine this "old" that has been sitting for so long? Is there anything I should look for?
btw, money is not an issue, just to avoid the cost considerations in your replies.
Any advice will be much appreciated.

Thanks in advance.

John
