Story:

Today, I am over at a friends house bench racing all things Corvette. As we are rummaging through his parts, I see this intake manifold. At first glance, it apprears to be nothing more than a Hilborn fuel injection manifold. Upon further review, this has casting dates and a casting firing order much like GM would have used. Can anyone give some input as to it's history. The manifold has bosses cast in for injectors in what seems to be the stock 63 F.I. location as well as bosses cast in right behind the throttle body. Given the 63 casting date, could this be a part of the original Grand Sport program? As you can see, the manifold did not receive it's final machine work.
In advance, thanks for your consideration
