Still looking for 262 twin h intake manifold.

Looking for a 262 Twin H intake manifold for a 53 SuperWasp.

Ol racer

FYI

I (think) the Intakes are identical just the carbs are little smaller...

Kerry, Sent you a PM.

I installed a standard Hornet Twin H and WA-1 carbs with no alterations on my '53 Super Wasp decades ago.  Made no changes other than jetting as the gasoline changed a little.   Back when we still had leaded fuel, that car had the prettiest light gray tail pipe residue - a sign of perfect fuel mixture.   There is no such thing as different Twin-H for the 262 to my knowledge.

WG- the shorthood 232/262 intakes are different. The carb base is smaller diameter than Hornet. Different Carbs used albeit Carters too. I too have Hornet Twin H on a 232. Use a Unisync to attain proper mixture.

The differences

Oldfarmer...  I appreciate your comments and the shadow in the "Hornet" pic is making it difficult, but aren't I looking at 2-3/4" measurement in both photos?   If not, what is the measurement difference?   And then what carb number would the 232-262 use if not the WA-1?  Can you supply both casting numbers?   Yes, a Uni-Syn is absolutely critical to making any small multi-carb engine run right.   

I'm still willing to learn in spite of my advancing age.  If I had the 'wrong' intake on that Super Wasp 40 years ago, I want to know about it!   Unfortunately when that car was sold it was sideswiped in Los Angeles with a very hard hit not long after the new owner got it.

You looked good 40 years ago ! LOL

very nice car.

I always thought the manifolds and carbs were the same , but metering rods and linkage and air cleaners were

different.

Hi:  The Senior or Hornet Twin H used the 968S or 2113S carb.  The Wasp Twin H used the 990S or 2114S there are different casting numbers as well as part numbers for the intake manifolds.  The Wasp carb stud spacing is 1/4 inch less stud center to center.    I have attached the Carter sheets for both carbs. Look at the carb base data as it identifies to differences.   As a note, I use the 968S carbs on the Hornet Twin H installed on a 232 engine. The metering rods have been changed to the middle lean rods.

FYI, It appears that the casting # for either 262 or 308 T/H manifold is the same (exc. Hash, of course) but the machine work & P/N aren't.
***346 is a 308 and ***347 is a 262 manifold, but both have the same casting #.

The point? If you are watching for one, the # that is cast into it won't tell the story.......you must do some measuring to confirm.

Explanations and details appreciated.  Old dog learned new tricks.   And yes, I did look good back then but gained some weight and a beard and I quit wearing dresses trying to fit in on the West Coast.  LOL   

That was one of the photos shot by photographer Glenn Embree using a professional model when he was under contract from NAPA stores for their old large format annual calendars.   Glenn is gone and my hunch would be that model doesn't look the same today EITHER.

Just to add a little more to all the great info above. I've got a 'Hash' style Twin H manifold on my '49 262, with the internal balance tube. This was also from a Hornet and has the wider carb mounting stud dimension. I have run a pair of 968's on there for many years, which like was stated above had to be leaned out quite a bit since they were designed to feed a 308.

Anyway, a few years ago a came across a pair of 990s carburetors, which was what Hudson put on the 262 Twin H set up. I had Walt Mordenti rebuild them last year, and have recently installed them on my later model manifold. It did require a bit of machining though. The cast base of the carb comes off easily with two screws and a linkage clip. Then I clamped these in a mill and made the round stud mounting holes slightly egg shaped to match the dimension on my manifold studs. Walt said that this has been done many times. By the way, the reason I wanted to install the 990s carbs was that I was never able to get my fuel mixture lean enough with the 968s carbs, and since I've got another cross country trip coming up this summer, I wanted to at least try to improve my gas mileage.

So I guess the point is that you can make pretty much ANY combination of carbs and manifolds work on either a 232, 262 or 308, but it might require a bit of tweaking.

Frank, thanks for the post.  I went to my storage today and confirmed the Wasp manifold I have set aside does indeed have the same casting number as the Hornet Twin H.

Hudson Guy... good information too.  I have wondered if the base off the 968 or 2113 could be interchanged.   Should have taken a look at the carbs too while examining the manifold. Made a note to look at that the next time.  Also, the Carter metering rods came in at least three sizes to vary the carb fuel management.  I settled on the leanest metering rods for the 968s and they allowed me eliminate the rich mixture of the standard rods.  

WG- Always liked your Wasp 2 dr and have kept a copy of that same picture in my files for years.

Back in 1971, I used a 262 manifold on a 308. I had rebuilt the Hornet carbs and restored the manifold, painted etc. When I assembled the parts I discovered it was a 262 manifold.  So rather than start all over.. I lock tighted studs into the original carb mounting holes. Sawed them off and drilled and tapped the manifold to the Hornet carb spacing. The bore ? I don't recall if I did anything about that. Ran just fine.  "still out there" I guess.

There are more differences than stud locations. You could (I think) interchange the base castings but venturi size, jets, metering rods, etc., are specific to the carb model and application. Sure, they run OK if not exactly correct, in fact, I'd make a small wager that a 308 would be fine.....maybe better, at low speeds with the 990S carbs but high speed performance would suffer with the smaller throat/venturi.
I once bought a "308" from a guy that had a Twin H set-up on it but I could see that something was amiss......A glance told me it was a 232 or 262. The latter turned out to be true and a very tired 232 it was. How an engine can run long enough to wear itself out that badly is a mystery to me. The Twin H was for a 308 but it was on a 232.....I can't imagine that it was a very hot performer. It had a '50 iron Pacemaker head on a wide block, as well. Needless to say, I didn't pay his asking price.
