Modified Ford Model Bs – Bill Holder @EngineBuilder

Modified Ford Model Bs – Bill Holder @EngineBuilder


It was known as the Model B engine and was produced for only four years beginning in 1932. Sporting only four cylinders, it was basically an upgrade of the earlier Model A powerplant. The “B” engine sported an impressive 200 cubic inches of displacement. Its compression ratio was a super-low 4.9-1. The paltry 50 horses it produced came at about 2,200 RPMs. The engine certainly didn’t appear likely to be a candidate for upgrading, but that wouldn’t be the case.

It was known as the Model B engine and was produced for only four years beginning in 1932, hence the ‘Deuce’ for that number in its model year

In addition to its carburetors, Winfield also produced a B Block compatible head, shown here.

The “B” engine sported an impressive 200 cubic inches of displacement. Its compression ratio was a super-low 4.9-1.

The paltry 50 horses it produced came at about 2,200 RPMs. Its main components included an ignition system, which included a coil and a centrifugal distributor.

The engine certainly didn’t appear likely to be a candidate for upgrading, but that wouldn’t be the case.

Shortly after its introduction, there was a wave of professional upgrades that evolved making every stock Deuce a potential race engine.

And, single-car garage engine builders would find many different ways of devising methods to triple, and sometimes more, its horsepower with a multitude of aftermarket and homemade performance parts.

It was a favorite of two types of motorsports fans.

First, there was the type that looked at it for performance street. But the performance improvements that were possible also made it an excellent candidate for oval track racing with the sprint car (then called big cars).

There was one common component in a majority of the conversions, that being a pair of two-barrel carbs, usually Winfields.

All these conversions could run on either alcohol or high-test (then called ethyl) fuels, but for alcohol, it was necessary to open up the jets for more flow. The compression ratios were also higher for alcohol use.

Established B Block Aftermarket Conversions:

HAL B Block Conversion

This high performance head was licensed by Chrysler for use by Ford. On the head was the warning to use high-performance spark plugs.

The HAL conversion was a popular racing conversion for the Deuce. This conversion lasted into the 1950s where it was still competitive. On some occasions, the block was bored out to about 220 cid.

Besides the HAL cylinder head, there was also a balanced crank, and either a single or double overhead cam. The latter was the preferred system if the pocketbook would allow it.

It also used a pair of single-barrel carburetors. It’s compression ratio was about 7-1. It was reported that some of these set-ups were capable of producing one horsepower per cubic inch of displacement, which was a pretty heady accomplishment for the time period

In addition, the very early HAL engines had carburetors sitting on top of the engine instead of the normal side-draft position. Hal B Block conversions have been noted with different displacements, some bored out to 220 cubic inches and sporting a balanced crank.

One restored 1934 HAL sprinter had an illustrious history and carried Flynn carburetors along with magneto ignition.

It burned alcohol. During its racing days, it won the NARA Northeast series and was reportedly driven by Indy 500 driver, Bill Holland

Dreyer B Block Conversion

Pop Dreyer was one of the best-known engine builders of the period. His cast iron heads connected to the B Block provided one of the best sprint car powerplants during the 1930s. The engine also sported twin Winfield carbs, aluminum intake manifold and a SOHC cam set-up. It was reported that these engines could produce over 200 horsepower.

He later would build a block of his own which would incorporate a double overhead cam and five main bearings instead of the three on the standard B Block

RAMAR B Block Conversion

This RAMAR conversion features a steel head, a dry sump soiling system, and 1.25 inch Winfield Carburetors

More New Flatheads – The Re-Engineered Model A Engine


A couple of years ago I did a post on the re-engineering of the Model A Engine by Terry Burtz, you can find the article here

Since that time things have moved on massively and Terry is in full production and selling not only the engine to the public but also many other ancillaries to match.

The new “Burtz” Ford Model A engine block is now available!  It features a 5-main bearing design and includes a dynamically balanced crankshaft and set of connecting rods. 
All remaining components needed to complete the engine build are stock Model A Engine parts. 

These include flywheels, cylinder heads and camshafts with probably more to follow

Also on the very comprehensive site are all the technical data and ordering information for this excellent piece of engineering.

Hotrod 4-banger with Cyclone head, Stromberg 97 and a Scintilla Vertex magneto – Slowshop & Custom @YouTube


Yay! I´m working on the Tudor in this episode. Installing the Cyclone 7,5-1 high compression cylinder head, building the header, installing the Burns intake manifold, finding out my “restored” Stromberg 97 is crap but install it anyway… A lot of things happening so I had to split this one into two videos. Part deuce is coming next weekend. Thank you for watching!



Please take a look at Terry Burtz’s Model A engine project, potentially very exciting!

Automotive engine design and analyses has changed dramatically and is vastly improved since the Ford Model A engine was designed and analyzed in 1927. Have you ever wondered why even the best rebuilt or highly modified Model A engine has a useful life that is just a small fraction of the useful life of a modern engine? This article will attempt to answer that question and present an engineering design study that demonstrates what can be accomplished by substituting four redesigned parts into a Model A engine. By substituting these four redesigned parts, a stock appearing Model A engine can have the reliability and longer life of a modern engine, and a hot-rodded engine will have a much higher probability of staying together. Readers of this article will also learn about modern engineering methodology, understand the reasoning behind engineering design decisions, and learn how a collection of sand cores can come together to form the cavities of a complex casting. For additional information, readers are encouraged to do Internet searches on the words, phrases, and terminology used in this article.  This article presents a summary of what has been accomplished. And lastly, this article has been written to determine if there is enough interest for this engineering study to continue and become real hardware. I apologize for the length of this article, but there is a vast amount of information to present.

Removing Valves from a Ford Model B Engine


Removing Valves from a Ford Model B Engine

As part of the inspection of the Model B engine it was found that the valves were seized due to the amount of time that the engine has been laid up.

1 / 7

With a bit of a two man effort and the correct Ford valve spring compressor and valve guide “knocker” tool the valves and guides were extracted. The guides and followers are in really good shape. Will most likely replace at least the exhaust valves.

Hagerty Redline: Freshly rebuilt engine goes back into the Ford Model A


Freshly rebuilt engine goes back into the Ford Model A

In the leadup to the next Redline Rebuild video, the Hagerty video crew has released three videos documenting Davin Reckow’s rebuild of a Ford Model A four-cylinder. While Davin knows his way around a domestic V-8, each engine family tends to have its own quirks. These “banger” engines are a whole different animal entirely, since they predate most common pushrod V-8s by an entire generation.

The excellent Hagerty Redline engine rebuild series has arrived at the venerable Model A. As you’ll be able to see Davin highlights the differences between the Model A and modern engines.

The Model A section begins at 5:05 in the video

In the next video Davin takes a trip to get the Babbit bearings poured, interesting end to process.

Now the engine has been freshened up Davin starts to fully understand the difference between the older and modern engines

Assembly continues on our Model A Ford engine. Almost ready to run!

Model B Engine Inspection


Took a trip over to strip and inspect the Model B engine, on the whole it was very encouraging. Looking at the stamping on the block it looks as if it’s a 1939 build.

2 / 12

The engine looks in great shape and we think it was overhauled maybe back in the 1950’s and then just stored before changing hands a number of times. The white metal big ends and mains are in reall good shape as are the timing gears. The issue at hand is a number of stuck valves which means we can’t turn the engine fully at this point. So, more soaking in penetrating oil and get back to it in a week or so.

B is for Banger – David Conwill @Hemmings



For 1932, Ford introduced an improved version of the Model A four-cylinder to accompany the new V-8 in its cars and trucks. This 200.5-cu.in., 50-hp engine was known, appropriately enough, as the Model B.

The Model B shared many elements with its Model A predecessor, and the two had a great deal of physical interchangeability–attested by the fact that today, many updated Model A’s incorporate some or all of a Model B engine for improved driveability. A prominent change between the Model A and Model B engines was the addition of significantly more bearing area: Larger diameter bearings for both the connecting rods and mains meant better durability and more potential for power.
