What kind of carburetor does a Ford engine use?
Beginning in 1934 production, Ford started using the Stromberg dual carburetor commonly known as the “97” which referred to the nominal venturi size of 0.97″ diameter. Stromberg identified it as their Model EE-1. A slightly smaller version known as the “81” (Stromberg EE-7/8) was used on the smaller 60hp V8 engines from 1937 to 40.
How many water pumps does a Ford flathead have?
The flathead Ford has 2 water pumps. You could easily think of it as two completely separate cooling systems (except the radiator). Here is a diagram of part of the oil system on a military vehicle that has had the flathead engine modified for a full-flow oil filter.
What is the difference between a Holley and a flathead engine?
Whereas the Holley is vacuum operated. The Holley is designed to open at 7 inches Hg (mercury). Most flathead engines in good shape running a single carb may make 18 inches Hg at idle. Change to dual carbs and the vacuum is about 12 inches Hg… probably less if you’re running a cam.
How much HP does a flathead motor make at idle?
Most flathead engines in good shape running a single carb may make 18 inches Hg at idle. Change to dual carbs and the vacuum is about 12 inches Hg… probably less if you’re running a cam.

The flathead Ford has 2 water pumps. You could easily think of it as two completely separate cooling systems (except the radiator). Here is a diagram of part of the oil system on a military vehicle that has had the flathead engine modified for a full-flow oil filter. The view is from the rear of the engine.
What did flatheads use oil for?
Apparently pre-1948 flatheads, as originally built, used oil from the engine fed from the front of that main galley down to lubricate the water pumps.
What causes a cracked block on a Continental F140?
I would say you have a cracked block. The pressure of the oil pump pushes the oil into the coolant. This is a common problem on Continental F140 engines. An internal crack usually after over heating leads to frothy oil in the coolant.
Does the camshaft have water?
Nothing apears to touch water here. Below that galley is the camshaft (and below that, the crank), which it oils. There is no water around a camshaft. The area you are looking at around the valley is just open. This is a crankcase vapor and oil drainback area. Those small holes by the lifters are for oil excess oil (not under pressure) to drain back to the oil pan.
What size jet should I use for a 1932 Ford?
I had used "California Bill's Ford Speed Manual 1952 Edition" reprinted by Fisher Books as a guide to the jet size. He recommends .046 jets for 1932 to 1948 engines, but was probably talking about 239 or even 255 cubic inch engines. Our engine seems to be bored .050 over so it should be about 228 cubic inches. Red of Red's Headers told me that .042 would probably be better, but suggested see how it actually runs first. I may just take it to the local garage with a flathead expert since my house has too much 30 mph driving between here and the highway to get a good reading on the plugs at home.
When was the Stromberg 97 carburetor made?
This was an easy choice for us: Stromberg 97's, although it's perhaps hard to justify. One reason is that the Stromberg was the factory carburetor in 1935 (although the Stromberg 97 wasn't used until 1936). And since they're older and rarer, there is more of a mystique to them.
What are the choke and throttle links on an offenhauser?
The throttle and choke linkage are just the standard Offenhauser parts. They may look a little clunky with cotter pins everywhere holding things in place but they are functional. Most of the fancier linkages have progressive mechanisms for three carburetors and are a lot more expensive. There are also some fancy ball bearing plain linkages too. Maybe next time. Red at Red's Headers advised that the choke might not be needed with two carburetors, but this is New England, not California, and we wanted to be able to use the truck in early spring and late fall so we got the choke linkages installed on the carburetors and also a linkage to connect both chokes to the choke rod into the cab.
What is fuel line fitting?
Fuel line fitting for the fuel pump that works with the carburetor fittings
Which is better, Holley 94 or Stromberg 97?
The flow rates are better for the Holley 94's than for the Stromberg 97's and seem to be a better carburetor for a single carb setup: after all, Ford replaced the Strombergs with Chandler-Groves and then got Holley to manufacture the Chandler-Groves design. But for a smaller engine, the smaller flower rates aren't a problem.
Where is the generator mounted on a cylinder head?
Instead, the generator is mounted on a bracket attached to one of the cylinder heads . But some of the older intake manifolds (including the ones still manufactured by Offenhauser) also have an option where the carburetors are closer together, both towards the rear of the engine to leave room for a generator.
Can flatheads have more than one carburetor?
Pretty much all the books on flatheads don't recommend more than dual carburetors for street use, and many of the newer books recommend putting on a four barrel carburetor instead of two carburetors. At the same time, two, three or more carburetors were the only choices back in the 40's and early 50's. Plus the decorative possibilities for multiple carburetor setups are almost endless: air scoops, velocity stacks, various types of chromed and polished air cleaners...
What carburetor did Ford use for the V8 engine?
Home Troubleshooting the Stromberg carb. Ford used the Detroit Lubricator single barrel carburetor on the early V8 engines for 1932 and 1933. Beginning in 1934 production, Ford started using the Stromberg dual carburetor commonly known as the “97” which referred to the nominal venturi size of 0.97″ diameter.
How to check float level on carburetor?
You would bypass the mechanical fuel pump and run a line from a fuel tank directly to the carb inlet fitting. Make sure the engine’s ignition system is OFF. Power the electric fuel pump and check the fuel level with the top off the carb. Make sure to drain down the fuel level in the bowl to about half. This allows the pump to deliver fuel and see where the needle valve shuts it off.
How to check fuel level on a car?
Make sure the engine’s ignition system is OFF. Power the electric fuel pump and check the fuel level with the top off the carb. Make sure to drain down the fuel level in the bowl to about half. This allows the pump to deliver fuel and see where the needle valve shuts it off.
How to test fuel pressure?
To test for fuel pressure, attach a pressure gauge to the output side of the fuel pump. Start the motor without racing it, and observe the pressure at idle speed. Next, race the motor for a moment and again observe the pressure reading on the gauge.
Can you repair a Stromberg carburetor?
If your carburetor cannot be adjusted for proper operation, it may require a rebuild by a competent technician, who is experienced in repairing the Stromberg carburetor. A simple cleaning and re-gasketing may not correct a carburetor with these and other defects. Worn throttle shafts and butterflies, leaking fuel floats, worn needle valve, clogged passages, warped castings, and other internal problems can best be corrected by someone with the correct tools, replacement parts, and repair knowledge.
Does a wide spaced manifold increase HP?
A wide spaced manifold (Super type) will make a very noticeable increase in hp over a narrow spaced one.
Can you jet a Holley 94?
I would run Holley 94's, you will be able to jet them up or down easily as well as pay with the power valves.
Do you need to take carbs off each time you change the jet?
Something you should think about too, is how high you want the carbs, since you can't access the jets with the jetwrench when the carbs sit direct on the intake, so to change the jet's, you need the take them off each time. Also carb riser change the airspeed and caracteristics of performance.
Does a carb riser change airspeed?
Also carb riser change the airspeed and caracteristics of performance.

Can you run progressive linkage on a 2 carb manifold?
DO NOT try to run progressive linkage on a 2 carb manifold. It is against Boyle's laws of physics.
Can you install elec ignition on a 50 Ford?
I like the 2 carb set up. I ran it on my '50 Ford. Best thing you can do is install elec. ignition. Starts every time. Follow with w pr. of headers.
