Thanks guys...okay - all good information! Didn't realize Blue Thunder made these! I bought it from a guy with a CSX22xx serial out of Colorado back in the early 2000s who passed the info to me. I have never installed or used it.
The "parallel" COBRA lettered intake drawing was dated October 2, 1963 but for some reason intakes did not seem to get to the Shelby race shop until maybe March 1964.
The H-M site offers this style advertised as made by Blue Thunder®.
http://www.holmanmoody.com/Intakes1.htmlThere are so many of this style intake sold by Ford, Shelby, and Dean Moon over the counter 1964-67ish it seems odd that there is a market for new made copies. There were a bunch of different in some way 4-2V intakes for the Weber two choke type downdraft carburetors between 1963 and 1970. This isn’t all the variants, just some interesting ones.
COBRA lettered “opposed” array with at least two different as cast port sizes for the cylinder heads
COBRA lettered “parallel” (lots of systems and bare intakes sold)
FAV (Ford Advanced Vehicles) lettered “parallel” in magnesium for Ford GT40s
SHELBY lettered “parallel”
COUGAR lettered “parallel”
Intakes for use with cylinder heads that had not been milled.
Intakes milled to fit when milled cylinder heads were to be used.
Reproductions of the COBRA “opposed” type intake were offered in mid 1982 magazine advertisements as part of new made aftermarket induction systems. A significant percentage of “opposed” type intakes I see offered for sale has been the 1982 and later copies.
