I sold this NOS LS7 engine last year for $6500. It was new and perfect in everyway:

It sold fairly quickly and the guy I sold it to had it on Ebay not too long later for $8000. It may or may not have sold.
I thought this may help with the value. I imagine you could build a nicer engine for less but the history and mistique(Sp?) of a LS-7 engine carries a lot of weight.
