Here are some pictures of a intake that I recently acquired, I compared it to a 1969 Z28 #3932472 and it is identical, With the 0-casting it is factory experimental aluminum Z28, Any idea how many of these GM may have cast for testing?. If John Z reads this maybe he would know being a former GM engineer. Thanks

The intake cast # is 0 322673
The intake date # is 1.3.69

69 Z-28: Fathom Green, X33, DZ302, M21, 4.10 Posi, Chambered Exhaust.

Definitely an experimental casting; note oil fill tube (not used after '68, even though manifold was cast 1-3-69) and choke stove rotated 90 degrees from normal position. Have no idea how many of these were made - that kind of paperwork is long gone.

Thanks John.

These were probaly provided to racers etc. Could have been a lot of them or very few, who knows.

Is it worth anything, who knows?
