Suspension? Most in this group will accept a modified flathead as long as it is period-correct, with no obvious modern technology visible. French blocks are about 30 pounds heavier than a standard flathead, which is a good indication of better metal and thicker walls. Let's go over what it takes to put a Flathead v8 into a stock model a Ford! Using a 3D-printed model of a Flathead V8, Engineering Explained's Jason Fenske goes through why this engine was perfect for its day, and what led to its downfall. The rumored new aluminum Flathead blocks are in fact a reality and are undergoing rigorous testing as this is being written. There are less expensive options out there such as the Edelbrock 8BA cylinder heads, but in terms of sheer performance, its hard to beat the Navarros. Blocks from 1932-42 use the same cam in terms of the lobe centers, while 1946-53 blocks use another (1949-53 cams have a gear on the nose to drive the distributor, thereby using a different front cover). Reputedly, they are cast with 10 percent higher nickel content, and the quality of the modern castings is a lot smoother with much less core shift. This was the legendary 3/8-by-3/8 Flathead, and it referred to the stroke being 3/8-inch longer than stock and the bore diameter of 3 3/8 inches. Younger guys yearned for a simpler, back to basics approach. A wide variety of headers are available for flathead engines, which certainly should not retain the restrictive stock exhaust manifolds. In 1948, the Ford 239 flathead V8 was given a 4-inch-stroke crank which increased displacement to 255 cid. Research has shown there's relatively little air movement over the base of the block. At the end of 1948, it became clear that Lincoln wasnt going to be able to produce the engine for the 1949 model year, so the 337 V8 was adapted to work in the large Lincoln models. Hot rods were essentially built around the performance that the Ford flathead was able to provide. While the flathead Ford eventually became antiquated by the rise of the overhead valve V8, it still lives on in the hearts of many due to its major impact on the history of high-horsepower motoring. Finally, there are brand-new aluminum blocks and Ardun OHV conversion heads and valvetrains. The V8-60, as it would be called, provided significantly better fuel economy than the larger 221 V8 which was meant to compensate for a lack of V6 options in the Ford catalog. The French flathead block is preferable due to its more modern casting, resilience to block cracking, thicker decks, and larger main bearing caps. Flatheads were now more reliable, and, more importantly from a hot rodder's perspective, they were better able to withstand hopping up. With its debut to the displacement-crazed American public, the Flathead was in constant production for 21-years ending in 1953. Plan on spending about $5K. Still not enough? By boring the block to 3 3/8-inch, a 296-inch Flathead was created. The redesigned cast-iron heads now had centered coolant outlets, and the combustion chambers were reshaped to accommodate domed pistons. Engine Facts has information on the 239 V8 by Ford and many other motors. Thread Starter. It's been over 50 years since the last Ford flathead V-8 was commercially produced in the U.S. BenLeBlanc, Aug 28, 2015. Our picks for the best Ford flathead V8 modifications include: Since the flathead has such poor airflow in factory form, one of the most common modifications is porting the block. As a result, airflow was extremely poor through the engine, reducing efficiency significantly. This time at the Quick Speed Shop I'm going to do a comparison test of two Ford flathead V8 engines. Currently the most popular approach is running a big popup piston, but with a scallop on the side adjacent to the valves to keep the transfer area clear between the valves and the cylinder bore. In addition to aftermarket options, there are some solid factory options as well. Manufacturing flathead heads since the 1950s, Navarro is known for build quality and high flow figures. By 1942, the V8-29A 238 flathead V8 received a compression bump to 6.4:1 and horsepower subsequently rose to 100 horsepower. Then, about 20 years ago, traditional street rods suddenly became cool again. Relieving is one of the most involved modifications to a Flathead. Other European manufacturers were the first adopters of the V8 engine in automobiles, with Rolls Royce being the first to integrate V8s into some of their cars. Keep it under 8.0:1.
Five Quirky Features of the Ford Flathead V8 - Mac's Motor City Garage Not much changed in 1935 except the material of which the pistons were made; some engines had steel slugs, others had aluminum, but a significant improvement came about in 1936. Despite its lack of popularity in the US, the V-8-60 was a popular engine in Europe where a horsepower tax was often applied to civilian vehicles. The physical limit of a flathead Ford is really dictated by airflow limitations and the fact that they are three-bolt main rather than five-bolt main engines. Up until 1942, valves were 52 degrees from vertical on the left side and 49 1/2 degrees on the right for an included angle of 101.5. It spawned the modern aftermarket speed-equipment industry and became a favorite of bootleggers, dry-lakes racers, dirt trackers, street racers, and a whole generation that just wanted a fast car. The 208-page softcover book has 531 color and 8 b/w photos, and is available from Motorbooks ( motorbooks.com ). By placing the valves next to the cylinder, air has to make two 90-degree turns in a complete cycle. Custom billets stretch all the way to 4.5-inch stroke. Flat-O Products sells well-designed, complete kits to install the Ford C4 automatic and T5 manual behind either 8BA or 59A engines. However, ever-frugal Ford used up the supply of babbit bearing blocks before installing the improved version. The current incarnation is 3 inches taller than the originals and has smaller 1 1/2-inch ports (vintage versions had 1 3/4 ports, but the new casting is thick enough to hog 'em out). With the introduction of the new 255ci Mercury in 1949, a 4-inch stroke crank was readily available. Recommended bottom-line street-gas-friendly compression ratios are between 7.5-8:1 on naturally aspirated engines and 6.5-7.0:1 with a blower. Edelbrock, Wilcap (Sharp), and Offenhauser continue to market a wide variety of intakes. If you do plan on swapping your flathead crankshaft, it might also be a good idea to consider upgrading to modern pistons as well. Criminally underpowered. Baron also offers a modern version of the famous Tattersfield/Baron four-carb race intake in more civilized street form. Current value is impossible to determine as it all depends on what has been done to the engine and if it is a running engine. If you enjoyed this article and are looking for more Ford engine guides, check out our Best Ford Mustang Engines In History Guide! The present-day Arduns are CNC-machined using high-grade 356-T6 aluminum, have refined combustion chambers, and improved oiling and valvetrain components. From the outset, Ford Flatheads had some unusual design features. Everyone knows it's a lot of work to rebuild an engine. You can now build a brand-new flathead. With a 4.5-inch-stroke aftermarket crank, that yields 334 cubic inches. Henry Ford revolutionized the automotive industry in more ways than one; however, the Flathead V-8 may be the best example of his bravado. The Flathead V8 engines produced by Ford Motor Company (USA) included basically three versions. Although new aftermarket iron blocks are reputedly under development, right now a real-world solution to finding a good core for your flathead is to start with a brand-new French block. Mullins, a leading purveyor of surplus Jeep and other vintage military parts in Texas, accidentally discovered a warehouse full of brand-new French blocks about to be junked during a European trip searching for Jeep stuff. The 2-inch rod journals are very popular because their diameter and width permits the use of readily available 215-inch-style Buick/Olds/Rover V-8 bearings. It isnt uncommon to see heavily modified flathead V8s pushing 300 horsepower, over three times what they produced from the factory. A good supply of new French (really) blocks exist and outfits like Scat make new H-beam rods and sell cranks with up to a 4.5-inch stroke. Year, condition, if a 60hp, 239 or 255, what all is included. 2023 Hearst Autos, Inc. All Rights Reserved. This means that the cylinder heads can be essentially flat as a board. Increasing compression could help boost power,. These second-design '38 1/2-'48 blocks (often referred to as "59A" castings) retained an integral cast-in bellhousing, used a distributor that mounts flush to the front cover with a horizontal shaft on the front of the engine and had insert-style main bearings but still used full-floating rod bearings (one bearing shell for each rod pair). In its final form, the 239 V8, renamed the V8-B3 and 8RT in truck applications, produced 110 and 106 horsepower respectively. There's a fine juggling act between compression and promoting proper transfer from the offset valves across the piston top. The flathead blocks to get are those with a 3 3/16-inch bore.
Planning the Right Ford Flathead V-8 Build - AutoRestorer flathead V8 value - Ford Truck Enthusiasts Forums The 270-F, Tatom's best all-around cam, is said to work well on normally aspirated or blown, stick, or automatic cars, with good idle quality and 18-19 inches of vacuum. Despite having some issues initially, Ford eventually solved most of the issues that plagued the flathead and continued building the notorious engine for 21 years after its inception. One popular procedure was to offset-grind a '46-48 Merc crank and use early full-floating rods for 1.998-inch journals. Swapping flathead pistons can solve some of the flatheads oil-burning issues, as oil is most commonly lost through factory flathead piston rings. But to Ford's credit, a great deal of effort-not to mention money-was spent on fixing engines at the dealership level and making corrections in design and manufacturing. Like most things, the Flathead evolved and there were a variety of improvements made during its lifespan. Strombergs were the favorites, but Chandler-Grove/Holley, Zenith, and Rochester two-barrels were also in use. Another significant change was the introduction of the legendary Stromberg 97 carburetor (although late in the year, the Chandler-Grove two-barrel would be installed, which would be replaced the following year by the Holley 94/Ford clone). As the name implies, polishing the ports means going a step beyond simply smoothing out the lumps and bumps and knocking off the rough edges-the ports are polished to the point where they shine (and it's a process that has found not to pay the dividends once thought).

As a result, the area between the valves and the cylinders is often made smaller to increase compression. It is beautifully restored- glass finish paint, genuine leather upholstery and a rebuilt flathead that runs as quiet as a mouse in slippers. The first-design '32 through early '38 engines had only 21 cylinder-head studs and until mid 1936 even used poured babbit main bearings. As for cylinder heads, Baron, Edelbrock, Navarro, Offenhauser, and Sharp (now sold by Wilcap) all have their adherents. At present, the only aftermarket custom oil pan available is from Ardun Engineering. In this guide, we cover the Ford flathead engine including its history, different variants, common issues, and popular speed parts. It is a common misconception that the Ford flathead V8 was the first V8 engine. The water pumps were now lubricated by oil rather than requiring a grease gun, and a new six-blade fan appeared on some cars destined for the warmer areas. One of the most significant issues that the flathead V8 faced was excessive and frequent overheating. However, with the GIs returning home from war hot rodding really took off. Ground with a 114-degree LSA and 112-degree intake centerline, it has 0.395-inch lift and 234 degrees duration at 0.050. Most builders convert the stock oil system to a full-flow design with a modern, remote-mounted oil filter. According to Baron Racing, the limiting factor is not piston-to-head interference, nor even valvespring coil-bind-it is running out of cam bearing clearance for the lobes. Although it sounds weird in this modern age of thin-wall castings, the 3 3/16-inch-bore, U.S.-built flatties can be bored 0.125-inch (1/8-inch-over). The Ford flathead V8 was initially only offered in a single displacement, 221 cid. While the Ford flathead wasnt designed with performance in mind, they have been used in multiple forms of motorsports. what FG said..hang tuff and wait for a nice rebuilt one..coming out for a Chevy SB swap. Magnafluxed or pressure tested a block is worth $400 to me .Untested whatever castiron junk is bringing.. 4 out of 5, I gave 750 for a early flathead out of a 1935 ford truck I got to drive for an hour before they pulled it out ran great no smoke or knock but I got the whole deal Motor trans and rear. Introduced on March 31, 1932 and produced in the USA all the way through 1953, the Ford flathead V8 must be one of the most well-known engines across the automotive world. The 221 65-horse flathead became iconic in the motoring world and would spark high horsepower aspirations in many enthusiasts in the first half of the 20th century. You will need to post a lot more information on them to get any dollar amount of their worth. This encouraged the old-time flathead parts guys (or their sons) to start repopping the old parts. In the old days the hot ticket was dropping a '49-'53 Mercury 4-inch-stroke crank in place of the Ford 3.75-inch-stroke unit. The MSRP is $35. Lot #55,040. The third-design "8BA" '49-'53 engines have a bolt-on bellhousing, the distributor was moved to the top-right of the engine, and modern insert-style bearings are used on both the mains and rods. Overheating, excessive oil consumption, cracked. Removable thermostat housings were now found at the fronts of the heads, which were retained by cap screws instead of studs, although there were still 24 per side and the pattern was the same. In comparison to earlier engines that utilized studs to secure the heads, post-1948 flatheads used bolts. The water pumps were moved to the front of the block so they pushed cool water into the engine rather than trying to draw hot water out, as did the head-mounted pumps. Traditionalists can go with Vertex or Mallory mags, while modern guys may want to move up to MSD or Mallory electronic distributors. It will use a new oil pan and special bolt-on universal bellhousing that accepts most modern transmissions.
Hot Rods - What Is The Current Flathead Value? | The H.A.M.B. I am looking for a non-restored running value with no smoke; Alright, I know what you are saying, but then what should I do? 10-16-2012, 08:59 AM.

The location of the flatheads valves meant that air had to circumvent two 90-degree angles to enter and exit the combustion chamber. It involved many more steps than we could ever document here, as well as quite a bit of specialized equipment. Improved internal components and casting technology make them more reliable and leak-free. Jun 7, 2007 By most accounts, other than what was produced by those writing ad copy for Ford, the V-8 got off to a rocky start in early 1932. Production of the 221ci engine ran from 1932 to 1936. As more time passes between the hay day of the classic muscle car and now, prices are, Read More What Are The Most Expensive Muscle Cars?Continue, It truly speaks to Carroll Shelbys legacy that nearly everyone stateside and abroad can conjur up a mental image as soon as the term GT500 is brought up. All flatheads overheat, then the blocks crack. French blocks have some unique features and are covered separately. But despite those initial issues, the Flathead was a pretty impressive piece in 1932: 221 ci with 65 hp at 3,400 rpm. As a result, the 239 V8 was created. At the other extreme are dry-lakes, Bonneville, and nostalgia drag racers who have applied modern technology to the point where in some instances it is questionable whether the engine still remains a true flathead: Once-85hp engines now produce over 400 hp on gas and have exceeded 700 hp on fuel-all this on an engine with only three main bearings. This Ford Tudor is powered by the iconic flathead V8 and this is believed to be the car's original engine. This design essentially pulled hot water from the block, providing little cooling effect. In fact, it essentially introduced the hot rodding scene to the world. One is the 239 cu in, 24 stud 59 AB engine and the othe. And when it comes to hot-rodding history, the Flathead Ford will always be a big part of it. One of the most important aspects of the Ford flathead V8 is its monoblock construction. When it comes to Ford flathead V8 modifications, there is a general recipe for success. Most hot rod engines use oversize valves. 2023 Hearst Autos, Inc. All Rights Reserved. Reversing the flatheads flow is another common modification on high-horsepower builds, although it is a very in-depth, expensive, and time-consuming process. Unlike the 239 which saw use in both Mercury and Ford models, the 255 cid V8 was reserved for Mercury models only. Post-1937 221 flatheads saw a horsepower increase to 85 and 94 horsepower depending on the cylinder head that was installed. Speed-O-Motive still advertises Merc crank cores if you want to go this route, but it's no longer necessary, what with all the aftermarket alternatives available. From the beginning, Ford made performance a priority in the Mustang, which is, Read More Ford Mustang, 1994-2024Continue. If you are planning on building out a Ford flathead for a hotrod application, it is important to consider which variant will work best for your application.
Ford Flathead Comparison: V8-60 hp and 59 AB - YouTube Due to the fact that the 239 and 255 shared a majority of components other than the crank, swapping a 255 crank into a 239 engine was a common modification amongst speed freaks. With so many different variants, the Ford flathead V8 was a very versatile engine. For reasons known only to the crazy French, flatheads were used in French Army trucks through the early '90s. ". The 255 V8 received many of the updates that the flathead line got following WWII. Trying to gain back compression ratio by using popup pistons may improve airflow provided proper attention is paid to the transfer area and overall piston-to-combustion chamber interface. and get all the new deets right in your inbox, Classic muscle car history, engine guides, performance modifications and more, Please enable JavaScript in your browser to submit the form, Best Ford Fox Body Mustang Performance Upgrades. This is always a "how long is a piece of string" type question, Ben. European sports cars have topped auction sales figures for decades, but that has changed in recent years. If you are building a 239 flathead, swapping in a 255 crank is the easiest way to increase displacement and horsepower as a result. The new engines overpowered the old chassis, so modern suspensions and disc-brake swaps were added to the mix. The 136 cid V8 was eventually discontinued in the US in 1940. The Ardun heads are 12-nches wider than a stock flathead Ford V-8 and consequently will not fit in most stock vehicles and they weigh at least 60 lbs. While that seems like a lot of engines, in reality, that was only a small percentage of the 212,238 flathead engines that Ford produced between March and December of 1932. At the end, though, you could never have guessed the engine they put back in the truck was the same one they originally pulled out. Fairly simple stuff like adding additional carburetion and improved ignition systems helped, but the time-honored modification to a Flathead was actually a three-part process-the classic port, polish, and relieve. Of course, this modern stuff requires a 12-volt electrical system. The Ford 239 was often called the "100 horse" motor for obvious . The flathead V8 got its name from the structure of the cylinder heads. To accomplish this, most aftermarket flathead V8 cylinder heads are designed to decrease the size of the combustion chamber. (3.06" Bore x 3.75" Stroke) The first-design flathead Ford V8 displaced 221 cubic-inches and had 21 cylinder-head studs. It was basically a copy of the Ford flathead 221 with a larger bore and some extra horses. They fit original '39-'53 blocks, French blocks, and (perhaps the ultimate evolution) Ferguson's new aluminum block. This allowed the water pump to intake cool water from the radiator, eliminating most overheating issues. Ford kept trying though and continued to install larger and larger engines, reaching a pinnacle with, Since the 1950s, few things have been associated as closely with Americana as muscle car culture. Over its production period between 1932 and 1953, the Ford flathead V8 received multiple revisions, ultimately leading to an array of different displacements and configurations. We may earn commission from links on this page, but we only recommend products we back. If money is no object, Navarro flathead heads are the way to go. Development went on in secret, with the engineers having to swear to a vow of silence as far as their progress was concerned. Buying a bare block is "risky" but if you do make sure it has no cracks ,has the main bearing caps and hasn't been over bored. That left Dorton quite a bit of room to grow. High-compression is the way to go. The Ford "Flathead" V-8 was first introduced in 1932. Solve cooling problems by using a modern water pump available through Speedway Motors and other sources. However, the main caps are beefier than traditional stock flatheads. ). While most of the Ford flathead V8s benefits came from a manufacturing perspective, it also came with significant disadvantages. Austin received a technical writing degree from University of Colorado Denver with the intentions of becoming an automotive journalist. Flathead engines are simple machines, at least as far as engines go. Re: Ford flathead v8 value. With modern aftermarket cranks and rods using modern insert bearings, 5,500 rpm normally aspirated is not a problem, even with only three main bearings. One solution is adopting a small-block Chevy damper.
Ford Flathead V8: The Original Hot Rod Engine - OnAllCylinders A car enthusiast since childhood, Chris Perkins is Road & Track's engineering nerd and Porsche apologist. Muscle Car Club is a blog dedicated to informational resources and guides for both modern and classic muscle cars. Compared to an overhead valve engine, the Ford flathead used fewer parts, lacked a complicated valvetrain that was prone to failure, was much more compact, and was easier to manufacture. Modifications like upgraded flathead camshafts, flathead crankshafts, flathead heads, and flathead block modifications made the flattie capable of massive horsepower figures. While pop-up pistons will certainly yield more horsepower, youll need corresponding cylinder heads in conjunction with them. Some fuel-injection setups even run distributorless coil-ignition setups. We may earn commission from links on this page, but we only recommend products we back. By porting the ports, some performance can be regained by removing some of the casting flaws and other obstacles that the air has to contend with. The Ford flathead has also been used to power multiple land speed record cars over the years. Even then, it's a gamble. Cadillac, for example, sold flathead-powered vehicles as early as 1914.
