499 performance center thoughts ?

A couple of questions you may want to ask.......
-when was it built?
-were all the parts brand new when it was built?

The reason for the second question is....... there are a few items listed that haven’t been available in quite a while......like the Crane rockers and the M1 manifold.
Also, I haven’t seen Indy valve covers like that in a very long time.

The main reason it would matter is in establishing the value.
If everything was new when built it would be worth more in my mind than if some of the parts in it were used.
