Anybody following the Twin-H setup on E-Bay? Item #180126019157, looks to be pretty good shape. No bids--- a little over one day left--is everyone waiting to "snipe" this item?

Is that the one that has a "welded repair" on it that appears to be JB Weld?

hudsonkid

It looks like it was welded, brazzed (spelling...) perhaps a nicer clean-up would make it less offensive, grind the weld down, paint it, you would never know. I personally feel it is pretty well represented, and a fair price. Unusual aircleaners.

I saw it but wasn't clear if it is for a 308 or a Wasp or Jet. They aren't interchangeable are they?

I know the Jet Twin H is much smaller and different, but are there two "full size" units? Reason I ask is that I have a NOS Twin H intake, but the bolt spacing for the carbs seems a little smaller than most of the WA1 carbs I have picked up at swap meets. Was there a "Hornet Twin H" and a Wasp Twin H?

are you guys sure that linkage is complete? i dont think so. -john

The Twin H intake and exhaust manifolds were the same for all 262 & 308 engines '52 thru '54. The carbs were jetted differently for each engine.

The setup for the '55 & '56 AMC 308's were different, and not interchangable with the earlier Hudson built units.

Jerry -There was or is 2 Twin H setups. A 262 (somewhat smaller carbs) and a 308. I have had both on my 308. Norm

Yes Herm, that's what I said above. The carbs for the 262 were jetted differently, and I guess had a somewhat smaller bore in the base.

That equalizer tube (?) running on the mainfold (below and between the two carbs) looks a bit different/odd...

THEGREENHORNET

rick your right, it does look odd, but i have seen them like that and also cast into the manifold like mine. im still not sure about the linkage.

'55-56 AMC 308 Twin H with integral vacumn tube. Linkage NOT complete. Air Cleaners not correct. Ex cracked at #6. Need to see underside, esp with heat riser off, to be able to tell if intake is not junk. they crack in the bottom wall separating heat riser chamber from intake plenum.....When they do , if they run at all, they run with massive vacumn leak, actually exhaust blowing into intake. Also, there are like six small stamped steel plugs in bottom of intake manifold, just under the carb bases, these often rust thru or fall out. Have to see and inspect these manifolds before purchasing. Lots of them are junk. Caveat emptor!

Ken U-tx,

Are the problems you mentioned exclusive to the 55-56 AMC units or to all Twin-H set-ups?

Dave

All Twin H manifolds have this as a potential symptom. you have to be particularly careful.

tristansdaz

Yep, this is a later manifold with the cast equalizer. Air cleaners are early 60s Chrysler of some sort. Buyer beware on this one!

I had the seller send me some additional closeup pictures of the Twin H setup which I then forwarded to my Hudson Guru. My guy was emphatic that this setup is for a 55 & 56 Hornet. If you try to put this on a 54 or earlier, you are going to have find a different pipe that runs from the manifold to the exhaust pipe. In my guru's word's the pipe is like looking for hens teeth. If anyone is interested send me your email and I will forward his response and pictures.

That manifold is for the 55 and 56 Hornets. The intake and exhaust manifolds will not work with the 51 to 54 set up. The equilerzer tube is part on the intake where 51 to 54 it bolts to the intake. Those are 2 expansion plugs that let you clean out the intake. Now here is the problem, the 51 to 54 exhaust flange will not bolt to this unit. You must have the correct flange and the correct front exhaust pipe. It has 968 carbs which fit the 52 to 54 cars and 55 and 56 take 2113. It will bolt to 48 to 54 engines but must change the exhaust route. Do not buy this unit before you can locate the flange. Walt Mordenti.

Walt's right! I ran into this the hard way. I knew I had a 55 Twin -H by the equalizer tube but didn't know about the different exhaust elbow. I did once I had it in my 54 then found out my elbow wouldn't fit. The later elbow will fit in the early car but it is not an easy part to find.
