63 Dated Intake Manifold Mystery
 

--------------------------------------------------------------------------------

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

-----Looks a lot like the Grand Sport side-draft Weber manifold but its been awhile since I have seen one. Hard to tell what modifications have been done to facilitate the injection, but a rare manifold all the same. Just looked again and it has never been drilled for the intake bolts. Wonder if this was somehow a bad casting and thrown out, and then retreaved by an employee or something.....Bill S

x2 looks like the Gran Sport intake manifold. Awesome piece!

There is a photo of the GS intake on page 245 of the book Chevrolet=Racing? Sure looks the same to me.

Perhaps Augie Pabst was somehow involved. He was a racer and insider at Chevy in those days-he owned the "Cherokee" '67 Camaro show car for years. And he lives in Oconomowoc, just down 94 a bit.

Unbelievable what pops up on this site... wow wow wow.
Few people even realize the 63 GS had a 377 cui all aluminum small block with huge side draft webbers...
Is there not a 0 (zero) part number anywhere on it?

curiously, the GS heads have a part munber, but do not have a 0- part number...maybe that system started later?? the earliest o- part ive seen was 1965...not that there are not any earlier

Just to clarify, I own &quot;0-&quot; parts from 1961.
