Hot Rods DeSoto Hemi intake query...

Don’t bother upgrading to the modern four barrel however given the opportunity to use multiple carburetors for no apparent reason I’m all in on that!!

I’m currently really resisting the urge to buy a dual quad intake for the small block in my truck

 

Agreed! And that is the reason (for a guy that polishes nearly everything) I painted it black. I wanted it to go away. If I was running an open hood car I would not have used it.

 

Or run a stock iron 4 bbl. Great for a stock motor.

 

Yeah, but finding a 4-bbl oem is not an easy task nor a cheap one. The usual problem then is using too large of 4bbl. Ya gotta remember that 276 inches, 7.5:1 c/r and crazy mild cam spec really prefer a small 2-bbl.

 

It sure is tough to find the OEM four barrel. Best to regularly check the classifieds here, as well as the Hot Heads swap site, if it's still going.

As for over carburetion, I bet the stock four barrel carb on the stock four barrel intake would work pretty slick...

 

We call it the "S.W.A.T. Team".

(So What's Another Thousand)

 

More carbs, more air, equals better fuel milage. At least that's how I explained it to my wife. 6 94s on my 276 Desoto

 

Its on a 2dr '56 Windsor V-250. Hemi motor with the Poly heads. Not many of these were made.

 

My friend has this manifold from a DeSoto, I’m sure he would sell it fairly if you’re interested.

 

That would work. Also, millions of 2 bl engines from the Big 3 have had 4 bl swapped on w/o ant other changes (cam, C/R, ect.)

 

Git off before she bucks. Or paint the 2bbl intake silver and be happy.

 

I’m pretty sure he has the carb also.

 

^^^^^^
That manifold has the exact same casting # as my avatar,,,,it’s genuine .
1955 291 .

Snap that carb and manifold up!
Is the goofy carb gasket original to the Desoto?

 

No self respecting hot rodder would stick with the stock 2 bbl if there was any other option. In the old days, guys even bought kits and made their own. I’d grab that 4 bbl and rebuild yourself a WCFB for now and keep my eye out for 2x2 or a 3x2 intake. JMHO, of course….

 

I have a Pete Williamson hi rise Dual Quad for my 330, here's what it looks like. Should make good N/A with the cam I'm going to run with Dual early Carter carbs.

Note the dual pop off valves; I was going to run it as a blown engine but changed direction and swapped out the blower plate for a dual quad plate with Pete in NZ.

Reckon it looks OK despite it being a modern casting. FWIW, sadly I don't believe Pete in NZ is making them anymore. Its a super nice casting indeed !

 

Maybe your wife will be happy.
Or..... she could say you shouldn't have.

 

The "goofy carb gasket" is unique to the 1957~1961 Chevy 283 2x4; one of several modifications Carter made to try to get a grossly over-carbed engine to idle.

Get the intake, the HH squeeze plate, probably a phenolic spacer, longer carb mounting studs & a 500 Edelbrock....

 

If the engine is truly a 276, consider:

DeSoto used no 4-barrel on the 276 (at least, I have no record of one).
DeSoto used a four-barrel of approximately 375 CFM on their 291.
DeSoto used a four-barrel of approximately 475 CFM on their 330.
Plymouth did use a four-barrel of approximately 375 CFM on the 276.

The Plymouth 4-barrel would be an excellent choice unless you plan to spend weekends at the drag-strip. (Then it would still be an excellent choice).

Years ago I saw a roadster with a Desoto engine running a modified Chevy aluminum 4 barrel
manifold. Don't know what size engine.

 

Jon ,
You are right,,,,,276 was 2 barrel only .
The 291 was in 1955 and it came with a 2 barrel,,or 4 barrel depending on the setup .
If I remember correctly the 4 barrel application was only approximately 10 % of the total production in 1955,,,,,so those intakes are sort of scarce .
But,,,I’m sure it would work alright on a 276 ,,,with the correct carb size .

Perhaps it was a SBC with Desoto Valve covers They are always trying to disguise those things.

 

Low deck DeSoto is low deck DeSoto....

 

Using the 291 four barrel intake on the 271 should work fine, with a small carb.

I installed a Ford 289-4V intake on a 260 with great success. After a couple trials, I found that a Holley 370cfm (sic) carb gave much better low to mid range power than a bigger carb. I couldn't notice a difference at high rpm.

 

The big frigging problem is that it isn't easy to find a 330 Desoto 4 barrel intake of any kind and stock ones with a cruddy core carb command 500 bucks. I've had the 330 I have since the late 80's and looked for an intake back then drawing a blank. Then life got in the way and it has been sitting in the shed since then. 2000 bucks for a rebuld kit, 500 + for an intake and probably another 2 K spent to have it ready to drop in a chassis is beyond my stack of coins limitation.

 

I guess it's just luck - I picked up a very clean 330 4bbl intake, heads and rods at a scrap metal dealer a couple years ago for $100, and sold the works off for $150 to a friend.
If I hadn't spotted them, I'm pretty sure they would have been sent out in the next load or two of scrap.

It's tough to tell these early hemi parts apart, I thought I was buying another 330 4bbl intake at a Washington state tractor swap, but it turned out to be the common 354 (Chrysler) unit. I was able to recover my money selling it to another Hamber, though.

 

Well, I am a self respecting hot rodder, and, I'm leaving it alone. I decided not to fix it until it's broke. I'm making a hood top for the car anyway, out of sight, out of mind.

 

I would buy the manifold and hang it on the wall. Don,t know how many times I passed on something and later regretted it. Some of those time I was told it ain't going anywhere unless you get it, only to find out they sold it to someone else because they were offered enough to make them sell it.

 

If it was closer I would love to have one! Mostly because I like to be different and Desoto hemis are different
