have seen a T with the intake turned downside up with an NH carb with a home made header. Has anyone run turn the T exhaust upside down?
Tyrone the orange car in this thread has the stock intake turned upside down and is running and NH carb.
Yes, run upside down. Yes, upside down and split.
What does an upside down intake manifold gain?
It would let you run a custom exhaust manifold a lot easier.
It's easier to use a vaporizer exhaust manifold. You can then use any kind of downdraft intake you like.
I don't own the car referenced in the link above (nicknamed Orange Crush by the owner) but was present when the intake manifold was modified.
Harry removed just over an inch of the manifold just above the 90 degree bend. That takes out much of the original constriction and allows the builder to further open up the passageway. It was then carefully welded back together and ground down to hide the modification.
You can see it in the picture that Robb Wolff posted in the link above. If I can find a close up picture, I will post it.
Hope this helps.
T exhaust manifolds are turned upside down in some marine applications. It is easier to direct the exhaust straight up if desired.
I would be concerned about running the intake manifold upside down as it could allow gas to leak down and onto a hot exhaust manifold. Of course, model T carburetors don't ever leak.
How would you get the gas way up there? Unless you got a 26-27, you'll need some good walking shoes.
