This block is completely beefed up, with four-bolt caps, reinforced bottom-end and webbing, furnace-brazed sleeves (max bore is 3.5 inches), and new-design head studs that tie into the bottom of the block. What you see here, however, isn't just a pair of reproduction heads atop a Ford block but instead a brand-new, 284ci, all-aluminum improved block, reproduction Ardun heads, and vintage 4-71 blower (the only old part on the whole deal) bolted to a new manifold from Ken Austin. Before he joined General Motors, Zora Arkus-Duntov, with his brother Yura, operated Ardun Mechanical Corporation in New York. While exact ignition timing will vary per combination, in general flatheads running gasoline like about 23 degrees total advance normally aspirated and just 19 degrees with a blower. Stay tuned for further updates on this project. Thanks ! or Best Offer. A look inside gives you the sensation of an open air concept that could easily be seen in many of todays homes. Finally, there are brand-new aluminum blocks and Ardun OHV conversion heads and valvetrains. The block also has a number of upgrade internally, in terms of its intake and exhaust ports, as well as its valve guides. Just a tall gray wall with a rolling bay door that blends so perfectly you may not even know it is a door until Don sticks his head out. His manifolds and valve covers graced the of the famous Hurst Hairy Olds twin engine car and he helped Craig Breedlove with the Spirirt of America record setting run. Flat-O Products sells well-designed, complete kits to install the Ford C4 automatic and T5 manual behind either 8BA or 59A engines. The heads and valve covers are made from 356 T6 aluminum, far superior to the alloy used back in the day.

Technical - 8ba aluminum block design | The H.A.M.B. What's an ARDUN? The Ultimate OHV Conversion for the Ford Flathead V-8 The mixture must follow a tortuous U-turn path out the block-mounted intake valve, over to the main part of the chamber above the piston, and then back out the exhaust valve. The fastest guys both naturally aspirated and blown run high-dome pistons. Yeah, you should be impressed. When I was in the ninth grade (56-57), our physics teacher "proved" it would be impossible to accelerate to over some figure like that (138 sticks in my mind) in the quarter. That first 50 G's supplied a blueprint -more or less- And that was all. Also, what does "wet jackets" mean? Schneiders 278F solid (0.420 lift, 250 degrees at 0.050 duration, 110-degree lobe separation angle) is one grind that falls within these specs. With a 4.5-inch-stroke aftermarket crank, that yields 334 cubic inches. Reliefs between the valves and bores are much less pronounced than the old days, only about 0.080-inch deep instead of the old-school 31/416 inch. Mostly true, but the French military used flatheads as late as the early 90s and ancient flathead technology has evolved to run over 300 mph at Bonneville. When I think about it, an aluminum flathead block makes no sense, economic or otherwise. This isnt any ol ARDUN-equipped Flathead, if theres such a thing, but rather the highly desirable V-8 from ARDUN Enterprises; now under the watchful eye of Don Jr. and Don the III. Ratios are 1.375 on the intake side, 1.2 on the exhaust. Stromberg in England is producing new Strombergs again. Get yours today. Charles Scott was also running an Ardun at the meet, a Hilborn-injected flathead nestled in the back of his Scotty's Muffler Service belly tanker. This encouraged the old-time flathead parts guys (or their sons) to start repopping the old parts. The old-timers took what they had and made it work. Where are the water jackets for coolant? For reasons known only to the crazy French, flatheads were used in French Army trucks through the early '90s. Only 200 original sets are known to exist, but fortunately, Ardun heads and associated conversion parts are back, reproduced in improved form by Don Ferguson of Ardun Enterprises. Turn-Key Engines - H&H Flatheads ARDUN ENTERPRISES Don Ferguson P.O. Before we get to the tech, some history: Ardun is a contraction of Arkus-Duntov, a name well known among the Chevy faithful, especially Corvette owners. Motor City also manufactures aluminum cylinder heads for Flatheads, and plans to build these all aluminum Flatheads in crate engine form. The Sharp 32 triple carburetor intake is one of the few that accepts Holley 94s and Stromberg 97s. Should you look into the trunk you can see forward to the dash. Normally we'd title this section "Cylinder Heads," but on a flathead, the heads-having neither ports nor valves-only form the combustion-chamber roof. He and Gene Mooneyham built and sold some of the first aluminum heads for the Chrysler Hemi. There are several reasons for developing a new aluminum block for the Flathead. Most hot rod engines use oversize valves. The bell housing mount is Chevrolet and I believe the water pump has a revision. Four carbs on a properly designed intake manifold offer the best distribution short of todays dry EFI systems. Ross, Wiseco, Egge, Arias, and others make pistons in any configuration you desire. Most stock flatheads never came with an effective harmonic damper. 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. $299.00. Two things to watch out for are an extra water hole in the block and the lack of a breather standpipe in the block. But that just leaves these pristine virgin blocks for us normal street guys. Ultimately, there are equal-length race headers available from Tatom Custom Engines. From its debut in 1932 to the end of its U.S. production life in 1953, the flathead Ford underwent three major evolutionary changes. The Southwind isnt a heater anymore but rather the housing for the fuse panel based on a Haywire system and wired to work by the RR&C crew. Next to the heater you will see a panel thats held in position by a pair of clips but its what rests behind the panel thats of interest. The battery and alternator were eliminated, and replaced with a magneto and . Denny is right.ALL of the above is true scoop! French blocks are hybrids, essentially a '49-'53 8BA in terms of deck height and front-end, but with the integral cast bellhousing and corresponding oil pan as found on the '38 1/2-'48 59A. Don Ferguson of Paramount Forge has designed an built aluminum FH blocks to be used with original or his Ardun Cylinder heads only. Five different intakes are available including 2x2s, 3x2s, 4x2s, a 4 bbl and a blower and they cost $1,000 each. One flathead builder, Dave Tatom, offers a unique line of custom grinds with wide 114-degree LSA for naturally aspirated engines, and 116-118 LSAs for blown motors. Although a great leap forward when it was originally introduced in 1932, by the '50s the aging motor could not stand up to the new generation of overhead-valve powerplants like the small-block Chevy. With 6 Ford Flathead Cylinder Heads for sale, and options to fit your needs including custom and direct fit Cylinder Heads for your needs. Tatom believes spreading the centers helps combat overlap-induced reversion with the flatheads siamesed center exhaust ports. 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. It was in the 40s that the Stewart-Warner Southwind used them in Fords. In order to gain this clearance, the hood sides where they meet the fenders were modified by being raised 1-1/2 inches yielding the necessary ARDUN valve cover clearance. 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. Terms Of Service. Standing out among the parts and projects is a flathead engine on a rolling cradle, fitted with Ardun cylinder heads and a S.Co.T. Seal the heads to the block using slick new graphite-impregnated head gaskets available from Best Gasket, Red's Headers, and Tatom. Available in center and front water neck. While exact ignition timing will vary per combination, in general flatheads running gasoline like about 23 degrees total advance normally aspirated and just 19 degrees with a blower. Most stock flatheads never came with an effective harmonic damper. Its only right. But with modern solid cams and big stroker cranks, overall engine rpm and piston speed is considerably higher than the old stockers. -Shadow Rods original cost of reverse engineering the Ford Flathead block was almost $50,000. Modern Ardun - MotorTrend Ken Austin grew up on a farm in Newberg, Oregon where his interest in cars started when he got his permit to drive to school. "These engines look cool, run cool, and are reliable," he says. Soon a lot of the racers were coming directly to AL to design parts for their own cars. Discussion in 'The Hokey Ass Message Board' started by Jimmy2car, Apr 26, 2010. Copyright 1995-2008 Atomic Industry: Steal our stuff, we'll kick your teeth in. Putnam also used the same leather on the center console and boot, the door panels, and the nifty accessory pockets in the doors. About the longest arm you can throw in a flathead, this Scat custom vacuum-melt 4340-steel. For improved cooling efficiency, original 49-53 pumps have more impeller vanes than earlier models. Most builders convert the stock oil system to a full-flow design with a modern, remote-mounted oil filter. Stay tuned for further updates on this project. 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. The downside was, as Flathead Engineering's Charlie Clark puts it, street rods "began to look about as exciting as a belly-button-everyone had one. On the following pages, well take a look at some of the stuff available for the flathead and also cover the lineage, interchangeability, and secrets of this proud forebear of modern hot rodding. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ). There are several reasons for developing a new aluminum block for the Flathead. Simple by today's high-tech standards, during its performance reign from the late '30s through the mid '50s, the flathead was unsurpassed for building go-fast power on the cheap. small block chryslers (head approx 23" ) will be 201, 217/218, and 230 cu in, the 230 is the only of the 3 that has a 8 bolt crank flange. Are you saying that theres a FLATHEAD in there ? The Ferguson ARDUN project (picked up where the late Don Orosco of Monterey Speed & Sport had progressed) is based on an aluminum Flathead block (with enhanced main caps and deep skirts, for those wishing Flathead numbing power) and enhanced ARDUN heads (significant design modifications); ARP hardware is used throughout the engine. 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. 4451 Ramsdell Avenue Also mounted to the column is an original knee-knocker Stewart-Warner mechanical tach run off the back of the alternator; another one-off piece by RR&C. One flathead builder, Dave Tatom, offers a unique line of custom grinds with wide 114-degree LSA for naturally aspirated engines, and 116-118 LSAs for blown motors. It offers adapter kits to mate GM automatic transmissions and Ford C4 automatics to 49-53 8BA blocks, as well as a variety of adapters to mate both early and late flatheads to most GM and Ford manual transmissions. He traveled from home to New Mexico then to Los Angeles and onto Sacramento where he located the perfect foundation for his new build. In 1947, they were commissioned by Ford to improve the output of its truck engines. 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. With such a small difference; its relatively easy to take a little off the Ford snout then slightly hone the inside of a Chevy balancer so it slips over the Ford crank. Some builders also recommend installing exhaust-port dividers to split the siamesed center exhaust ports. New stainless valves are available from several sources. As we go to press, word is just in that Mark Kirby at Motor City Flathead has joined forces with Shadow Rods to develop an all-new, improved 49-53-style aftermarket cast-iron flathead block. The Thickstun two-carb high-rise intake (today marketed by Baron) is an excellent street setup and it even provides clearance for the stock generator. The new Sharp V8 60 flathead cylinder heads with front water neck. He also makes a pan for his block that is supposed to work on a stock block? Guys who once dreamed of owning a flattie back in the 50s but who had neither the time nor the money were now in their 50s, with lots of disposable income. But with modern solid cams and big stroker cranks, overall engine rpm and piston speed is considerably higher than the old stockers. Aluminum Flathead engine? | The H.A.M.B. The company they formed to produce these heads was named "Ardun," an acronym derived from their last name. But remember, we are talking about a seriously outdated engine design favored by a bunch of nostalgic old coots. Posted: Sat Mar 19, 2016 6:17 am Post subject: Re: Chrysler 6 cyl flathead. Written by Mike Herman and Tony Thacker, foreword by Ray Evernham. Because the French version was used in trucks, the intake- and exhaust-port throats are choked down under the valve pockets, so extensive port-work is required for racing. Click below to preview or download the complete catalog. You have to beat him/her at the same game. This site uses Akismet to reduce spam. Ultimately, you can move up to one of Cornhusker Engineering's custom front cover and late-model water-pump setups. What's the deal with that thing? Besides the Ford flathead, H&H also specializes in Ardun conversions as well as rebuilding other vintage engines including Y-Block Ford, Nailhead Buicks and Chrysler Hemis. Solve cooling problems by using a modern water pump available through Speedway Motors and other sources. With modern flatheads routinely putting out 250-300 lb-ft of torque, the original trannies obviously arent up to the job. Centerforce offers clutches and flywheels. The gas tank was supplied by Ricks Tanks as was the in-tank EFI pump. Over the meticulous bodywork performed by RR&C, a 1940 Ford factory color was applied. Short of machining the block oversize for custom roller-cam bearings, even with a reduced base circle this limits max cam lift to about 0.460 inch. With such a small difference; it's relatively easy to take a little off the Ford snout then slightly hone the inside of a Chevy balancer so it slips over the Ford crank. MCF's born-again flatty will come standard with a 3 1/2-inch bore and 1/8-inch-thick cylinder walls, thanks to special insert sleeves. The front fenders were then modified to allow for valve cover clearance. The man behind it all is Mark Kirby of Motor . Don Sr. has passed away, but at the shop with us was Don Jr. 's son Don III.). The Flathead in the five-window coupe is the test mule, and Motor City plans to begin production soon. Just sold him a fresh batch so I assume he's still building engines? A truck oil pickup tube assembly (PN 8RT-6615) is required to use the M-15 as well as the standard volume Melling M-19 in 48-and-earlier engines; 49-and-up engines can use the stock pickup. Ross, Wiseco, Egge, Arias, and others make pistons in any configuration you desire. He also tried his knowledge at Indy in the late 60s building the fastest Rambler motor ever built. "I can make whatever you want, but 350 horsepower in a hot rod will smoke the tires all day long.". There is also an Australian outfit, Flatattack Engineering, offering plenum-style, TPI-like systems controlled by either GM Delco or MoTeC computers. Don Jr. was the man showing us around the shop; his father was a longtime land-speed racer in whose arsenal were Ardun-equipped motors. What am I missing here? Whats right for your engine differs per application. The new Arduns have lighter 11/32-inch-stem stainless steel valves and accept modern 12mm, Save another 70 pounds with Ardun's new aluminum block. French blocks are about 30 pounds heavier than a standard flathead, which is a good indication of better metal and thicker walls. There are kits to install Weiand and Magnuson superchargers, or even one or two GMC 71-series blowers. Four-bolt center main cap. Again, this is one of those hot rods that you must see in person to appreciate the amount of creativity and craftsmanship that was invested in this ride. Custom billets stretch all the way to 4.5-inch stroke. Now its 2005, and the flatheads resurgence shows no sign of diminishing. 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. Most of these parts became the foundation for the Sharp Speed and Power Equipment company.

While enduing lifes ups and downs, hes held steadfast to what he likes in vintage tin, a 1936 Ford coupe. There are builders on the left and right coasts and all points in-between who assemble reliable, powerful, 150-200hp engines, or you can buy new parts and build one yourself. Like all fads, once started, the process fed itself. 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. If it boils, steam pockets form, and when you have steam, you'll get cracks. Baron, Edelbrock, Sharp (Wilcap), Navarro, and Offenhauser make both old-style heads as well as improved new configurations. He has even made some aluminum. 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. They fit original '39-'53 blocks, French blocks, and (perhaps the ultimate evolution) Ferguson's new aluminum block. Around 1998 Ken began making Ardun intake manifolds for a friend. You need lots of timing to make a flathead run. First invented in the 30s it was 1934 when Stewart-Warner eventually produced over 3 million for use in cars, planes, and military vehicles. An ARDUN Powered 1936 Ford Coupe With 400 HP! - In The Garage Media For even more protection, install a crossflow radiator and increase coolant system pressure to 17-21 pounds. Too high a compression ratio and the engine peaks early due to restricted top-end breathing. Googled Don Ferguson Aluminum Ardun Flathead and came up with an article on the old R&C Hot Rod Network with pictures of an aluminum FH style engine using the Ferguson built block that was assembled by H&H. York and his staff used their substantial talents and blended a Roadster Shop chassis, an ARDUN Enterprises V-8, and a beautifully massaged 1936 Ford coupe with just the right number of modifications to bring this hot rod to life. 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). Available in black t-shirt or white t-shirt. There are over 50 different flathead intake manifolds, but they aren't all created equal. However, there are some significant differences in French blocks compared to the originals. Improved internal components and casting technology make them more reliable and leak-free. Copper head gaskets are sold by SCE. Orosco had 30 sets made, sold all but two (one set is on the So-Cal coupe), and realized the undertaking was more than he wanted to continue. Subscribe to our RSS Feed, or use your favorite social media to recommend us to friends and colleagues! Whether they were or were not intended for use on Ford trucks, and whether they were or were not copied from the French Talbot design, and why they are so similar to the early Chrysler Hemi are all points that have been argued before. French blocks have some unique features and are covered separately. The search lasted about two years before Amie found the right car. Fabled Stromberg 97 carbs are back, but you can also upgrade to modern Holley four-barrels or even electronic-fuel-injection systems. 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. Short of machining the block oversize for custom roller-cam bearings, even with a reduced base circle this limits max cam lift to about 0.460 inch. The Motor City/Shadow Rods block is an entirely different piece. K&F Show #258: The Masters and Adam Sandlers 74 Duster; Movie Review Revisit Happy Gilmore! The street version of the ARDUN-equipped Flathead produces about 1 hp per cubic inch unblown but with a S.Co.T. The present-day Arduns are CNC-machined using high-grade 356-T6 aluminum, have refined combustion chambers, and improved oiling and valvetrain components. The new block is capable of much more horsepower because of additional webbing and four-bolt mains. There is also an ugly governor mounting boss on the left-rear of the block that many rodders prefer to machine off. Powered by vBulletin Here you can find some details and specifcations for the newly engineered flathead block, not sure how old this information is? These Lincoln V12 Smooth Aluminum Heads are made in the USA and have the water outlet in the stock location. 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. The fastest guys both naturally aspirated and blown run high-dome pistons. Just where did this engine come from? blower it can achieve another 50 hp with 5 pounds of boost. Just sold him a fresh batch so I assume he's still building engines? As the story goes, the owner really didnt want to part with the coupe but six months of perseverance finally netted Amie the decisive weekend of negotiating when a deal was made and the coupe was brought home. The street motors, on the other hand, typically put out "about 1 horsepower per cubic inch, unblown," he says. They're made in USA, complicated and produced in small numbers and that is reflected in the price of approximately $15,000/pair. Other appointments include the Autotrend EFI with a Holley HP ECU, an electronic ignition housed to look like a vintage magneto (possibly a Vertex), an MSD coil, cloth braided spark plug wires, while the juice is derived from the trunk-mounted Optima RedTop battery. 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. Great info ! He bought the entire French stock, and at last count still has at least 500 blocks, 120 complete engines, and over 2,000 rods. For this group-whether building a rat rod, yanking a Chevy that just doesnt look right in that old Deuce, or building a brand-new car-the outlook couldnt be rosier, even better than the flatheads heyday so long as the bucks hold out. He was basing his calculations on the assumption that a coefficient of friction of over 1.0 could not be achieved. Hilborn and Ardun Enterprises offer EFI conversions that look like old-time stacks but with EFI nozzles. Of course, this modern stuff requires a 12-volt electrical system. 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. Some fuel-injection setups even run distributorless coil-ignition setups. Speedway Motors offers pumps with sealed bearings that do an even better job in both early and late configurations. Apparently, the old boys network doesnt want any youngbloods crashing their exclusive country club. The times they were a-changin', and change was happening fast. But I digress. How bout Uncommons twin 4-71 top-mount system, shown here in m, Reds Headers offers more than 60 different flathead header sets including this stream-lin, Tatom offers equal-length headers for all fat fenders and roadsters. we're not talking about how much money you can spend breaking a record set by someone following the rules. A wide variety of headers are available for flathead engines, which certainly should not retain the restrictive stock exhaust manifolds. Don asks. Its a Holley touch screen that allows one to manage the computer settings. Then, about 20 years ago, traditional street rods suddenly became cool again. 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. Privacy Policy. TractorData.com Ford 2N tractor information We are always coming up with new products including Navarro air cleaners, Navarro 471 Blower Kits, V8 60 adjustable lifters, and the NEW S.Co.T. Chrisman, Rathman and others had Al build custom parts for their cars. All new design for 2019 is based on one of our favorite builds the blown, Ardun flathead. Navarro High Dome Heads are designed for special high performance applications. 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). The best balance has been the subject of debate for over 60 years. "This year's Nationals saw the mass use of overhead valves," said the magazine. There are several reasons for developing a new aluminum block for the Flathead. Since there have never been valves, seats, springs, etc they are very strong. The two most common Flathead motors are the 59AB (1946-1948) and the 8BA (1949-1953). Not many of the heads were madebest guesstimates put the number at 200 to 250 sets, with another dozen or so made for the smaller V-8/60 enginesand a few more were built in England during a short association Duntov had with Sydney Allard and his J2 sports car. You can now build a brand-new flathead.
