Has anyone used the Rex headers in a 56 F100. Just wondering about clearance from the firewall on the left side. It looks from 
measurements it will clear my steering shaft. How good is the ceramic coating?  Thanks

i used the right single manifold on the drivers side,this makes a nice curved pipe that mines oil filter and steering .pasenger side used  the tulip with centre exit

Thanks for your idea, i was really looking for a header setup.

The collector, right where the 4 tubes fit together will be about 4" diagonally, between tubes and the 2 1/2" flange will be considerably larger than the stock car manifolds.  Since stock manifolds don't work, unless you do what meteor said, these most likely will not either, because they are larger

There are lot's of options for truck headers, Reds, Sanderson, Patriot (which is rebranded by Speedway Motors, and others).

Thanks for the info.  My second choice was the reds headers. I will check with them for some measurements.  Thanks

I carry these in my 56f100 and they fit without any problem

Here’s a picture of the Sanderson headers for the pickup applications.  This particular set was used in dyno tests comparing the various Y headers and manifolds as well as an extensive cylinder head dyno test.  This particular set was donated to the cause by Charlie Burns.  Thanks again Charlie.

And here’s the link to the thread showing the dyno test results for the various exhaust manifolds and headers.

Those headers would be a good option, but when  i installed the automatic  AOD transmission i needed  to install side engine mounts at the 
middle of the engine, because the bellhousing did the rear support.  So i will need something that routes over the top and down.  I have seen a large 
front engine mount on some other engines, but the only other support i would have would be at the tail shaft of the transmission. 
That looks a little to unsecure for me.  I thought about fender well headers but not a big fan of cutting the fender liners.  Any other ideas would be great.

If I'm understanding, you're looking for passenger car headers (to clear the side motor mounts) that clear everything else in a truck. No clutch linkage, since it's an AOD, do you still have the column shift for the auto?

I had a set of Red's tri-Y' on my bird, and currently a set of FPA's. I know those won't clear the side mounts. None of the truck headers will. So your looking for a solution not many people need.

I understand on the fenderwell's. My best guess is maybe Red's current Tbird headers. The birds are tighter at the drivers side, just as the factory cast manifold is, and the flange is right off the tubes. That gives you more leeway on running the down pipe. I'm guessing the passenger side won't be a problem, but I'm not familiar with trucks.

Take a look at the factory cast manifolds for cars or birds. If you think you can work with that, then those headers (high and short vertically) will probably work if you can deal with the down pipe. Look at Ted's exhaust test, it might or might not be worth the effort from a performance standpoint from a cast manifold.

Otherwise it's going to be a custom build. If you go that route, post back. I know who builds the SS flanges that FPA uses and he used to sell them.

FWIW, the workmanship and coating on the Red's tri-Y's was top notch. 15 or so years ago.

Thanks for the ideas. I am using a floor shift for the automatic. I emailed Reds asking for dimensions on the F100 header for the volare 
front end, even though i am using a straight front axle.  I will look into the tbird headers but i did not see them on the site. Right side exhaust wont be a problem,  if  that works ok i still need to get around the brake booster under the floor and the inside the frame rail gas tank on the left side  for the panel truck. If you have a contact for the ss flanges  i would be interested.  Thanks again.

I think (but don't know) that Stan's builds the FPA headers I've got on the bird. When I enquired about flanges FPA sent me to Stan's, and I used those for the headers on my F code roadster clone motor. Stan does a lot of hot rod stuff, including the exhaust from the Sanderson headers back on my buddy's Nomad and numerous other acquaintances. They don't show on the site, so you'll have to call and ask. They're less than 15 minutes from me, and I drive by them once a week.

Thanks for the information.  I will definitely get in touch with them, looks promising.

What about Truck Rams Horn's, would that work for your setup?  Ted our moderator, tested them some time ago, & found them to be quite effecient. And a likely a lot less noisey... 
By panel driver - 4 Years Ago
I think they exhaust in the center of the engine.  Anything at the center of the block on the sides won't work. Thanks for the idea.

I have been thinking about using the red's dual tube headers for either a passenger car or a t bird. I was wondering if anyone has 
either one of these on their cars.  I was hoping i could get some pictures with measurements to see if i can fit these on the truck. 
I spoke to victor at red's headers and said he did not have a set in stock to measure. I can't use the standard truck headers,  unless
i remake and reposition the side engine mounts, because of the AOD automatic setup.  Thanks.

Panel Driver:  In Teds tests of exhaust setups, the Reds 2 Tube Headers, compared to regular 1957 exhaust manifolds, were a waste of time & money   installing  .The only thing they ad is noise & heat.. In fact the '57 exhaust manifolds were slightly better performers..
By panel driver - 3 Years Ago
I may have described them incorrectly. I was thinking about the Red's 4 tube headers for 55/56 cars. 
But i would be open to the 57 dual exhaust manifolds, if  someone would have a set for sale 
and they would have a chance of fitting.

Repo manifolds can be bought new from TBird suppliers.
By panel driver - 3 Years Ago
I was looking at the ones from Casco, are they the same measurements as the original 57 manifolds?  
Do you know how good the quality is? I need to call them but i  have been sidetracked lately.  Just
wondering if you have purchased from them in the past. Thanks

Casco is a well respected supplier to the restoration market. Everything I've had from them has been fine. But the driver side manifold is different for the bird, and that's reflected in the pricing. A good used set off a passenger car would probably work and be more reasonable price wise. Just watch for broken ears from over tightening and using gaskets.

If i use the 57 manifolds, i will probably use a new set.  Thanks for the info on the quality.

I'm posting an update for the Rex headers in a 56 F100. I've been working on a project over the winter.
Installing the Rex headers and independent front suspension.  
To make a long story short. I moved the engine forward to make the headers 
clear the firewall.  Here's a couple pictures.  http://forums.y-blocksforever.com/uploads/images/6dfafd45-239b-4f16-bce8-7891.jpghttp://forums.y-blocksforever.com/uploads/images/1ada5206-13ca-4ee4-9d19-f8a6.jpg
