Pardon my ignorance, but I am wondering if anyone has tried to adapt the earlier 55-56 T-Bird aircleaner (or a dry-element repro) to the later wide pattern Holley/Autolite carb?  Would it be too tall to clear the hood, or are there other features that preclude?
Also, while totally eliminating the manifold exhaust heat (Mummert manifold, block-off plates, etc.) would undoubtedly increase hot weather performance (cooler mixture), I wonder if that might lead to carb icing/stalling in sub-freezing winter driving conditions, or has ethanol fuel possibly eliminated that issue?

Daniel, I've got the dry type repo on an AFB style, same throat size as a Holley. Send me a pm with your email, I'll send the pictures and a brief explaination.

Any 57 TBird air cleaner will fit a later Holley, Edelbrock or Autolite carb.  The top part is similar to the 55/56 style.  It is a low profile air cleaner so you shouldn't have any clearance problems.

As far as the heat passage in the intake, there is an intake  gasket with a smaller hole it it.  This reduces the heat.

Not really to my point.  Anyone out there with a Mummert intake or block-off plates who drives in sub-freezing weather using gasohol with no stalling issues?

I'm running a couple of Blue Thunder manifolds blocked off. Never had an icing problem, but I'm not often out in cold weather. Really cold isn't the problem, it's a factor of temp and relative humidity. Since alcohol or ethanol has a higher evap rate than gasoline, my guess it's worse, but I don't know.

Here's an aviation chart, icing being a serious concern, and carb heat being manually controlled in light aircraft.

Guess I should just accept that manifold heat appears to be an obsolete concept (?). It's only that I like having an all weather (excepting deep snow, of course) backup vehicle. The small amount of exhaust heat that enters the tiny hole in my truck-type intake gasket may or may not be effecting the Bird's cold weather reliability. I just hate to gamble with changing what works.
This issue only came up because I occasionally see good 'B' iron manifolds for sale cheap. I had always planned to install an aluminum Mummert when completing my backup motor, but if the lack of carb. heat limits me to warm weather driving, I might decide to save a few bucks and tolerate the extra weight.

Blue thunder is still an option if you want to retain that feature and have a very good, light, aftermarket manifold.

I also would like to know if anyone has a Mummert or original blocked off and drives year round, in all conditions.  I might try blocked off gaskets one day, but it probably won't be any time soon.

Hi Daniel
 
Forgive my ignorance  but is this a water heated spacer?

Yes, but that model won't work on a Y block due to the open area for the PCV port. I don't know of any way to seal it against the manifold..

I have a B manifold with the heat passage completely blocked.I drive the car year-around,as long as the roads are not snow covered.This is in temperatures ranging from low teens to low 100s.I've never had any problem with icing(or overheating either).I've driven it this way for almost 20 years.It's a bone stock 292 in a 56 Fairlane.
