I recently tried to install what I thought was the correct air cleaner to manifold heat shroud for my '66. This is a '66 289 Mustang, built in December 1965 at Dearborn. While my car still had the original air cleaner and snorkel when I bought it in 2008, the heat shroud pipe was missing (as most probably are now). In fact, I didn't even know anything was missing until I looked at Bob Mannel's book. Guess that explains why so many passenger side exhaust manifolds had that mysterious threaded stud installed!
I sandblasted and restored what I thought was the correct heat shroud for a '66 289, but something is wrong. Though the shroud will slide physically into the air cleaner snorkel, it's almost as if the heat shroud pipe is too long, and it makes the air cleaner sit up too high. I checked at NPD, and the heat shroud they show has a substantial curve to it, whereas mine is straight. I'm thinking I have a heat shroud off of another mid-sixties Ford.
Here's what I have. Oddly enough, my air cleaner snorkel doesn't have that notch cut out of the bottom (for reference, there's a corresponding locator hole cut into the heat shroud pipe, almost like a locator hole). Does this mean my air cleaner snorkel has been changed at some point?
And finally, is this the correct air cleaner snorkel?
