Is this engine a good deal?

[KellerRacing]

The seller bought a 351W SVO crate engine in 2001 (the 385HP version), but it has never been fired. It has been wrapped in plastic since being delivered.

I don't know if there is any reason not to buy an engine that has been sitting for five years. Is there?

My understanding is that these engines, new from Ford SVO, are going for $7,500. The seller is asking $4,500, delivered anywhere in the US. He might even take a little less.

I'm a few months away from building my car, but this seems like it might be a good chance to save a few bucks by buying the engine now. Is it?

Here is what the seller has to say about the engine:

This 385 bhp (when used with headers and a 780 cfm Holley carburetor - These Parts Not Included) engine is the fastest and easiest way to add performance and reduce weight in your project!
