Stromberg in England is producing new Strombergs again. The new block is capable of much more horsepower because of additional webbing and four-bolt mains. And Don has rimmed the valve cover with an O-ring for leak-free sealing. If anybody is following Terry Bertz and his five main bearing cast iron Model A block, you'll know the heartaches and headaches he's been dealing with and the only solution to his problems was to go across the Pacific. They fit original '39-'53 blocks, French blocks, and (perhaps the ultimate evolution) Ferguson's new aluminum block. 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. (Yes, gasoline!) Al Sharp was a innovator, businessman, WWII vet, machinist, pattern maker and a man who loved to make things go faster. Copyright 1995-2008 Atomic Industry: Steal our stuff, we'll kick your teeth in. We've seen the dyno sheet, which also reveals the 396.9 lb-ft of torque produced at 4,300 rpm. Back in the old days, all cars used low-pressure cooling systems, so coolant often boiled. Flat-O Products sells well-designed, complete kits to install the Ford C4 automatic and T5 manual behind either 8BA or 59A engines. The frame was fitted with brackets to accept a blown ARDUN V-8, TREMEC TKO five-speed, clutch pedal, power brake booster and pedal, and plumbing package, which includes stainless steel brake lines. 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. 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. When I think about it, an aluminum flathead block makes no sense, economic or otherwise. The best balance has been the subject of debate for over 60 years. With that motor, the Chrismans won the B Comp Coupe class and set a new class record of 160.178 mph. Lifters look nearly identical to the originals, except his are made from solid chilled iron. Large-diameter, unshrouded valves combined with a proper combustion chamber configuration and piston design are needed to promote the proper transfer area from the flatheads valves to the far end of the chamber over the piston tops. Just sold him a fresh batch so I assume he's still building engines? Improved internal components and casting technology make them more reliable and leak-free. 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. 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. Somewhere in the middle is the largest group: Potential street rodders who just want reasonably fast hot rods without having a cookie-cutter, 1-800-car. Flathead gurus like Don Ferguson and Tony Baron strongly urge that hot rod engines run a harmonic damper. 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. Edelbrock, Wilcap (Sharp), and Offenhauser continue to market a wide variety of intakes. It comes with the standard REVO IFS with drop spindles, splined sway bar, upgraded to Penske double-adjustable coilover shocks. A high-pressure system will run fine with no boiling, even at 190-210-degree gauge temps. I'd love to retrofit my 36 Ford coupe back from it's current 302 to a flathead. But I still have one dumb question.how does this block in video cool? Ground with a 114-degree LSA and 112-degree intake centerline, it has 0.395-inch lift and 234 degrees duration at 0.050. i plan on building a T bucket in the next year and want to run a flatty. For improved cooling efficiency, original 49-53 pumps have more impeller vanes than earlier models. Notify me of follow-up comments by email. The best balance has been the subject of debate for over 60 years. 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. Many hard-core guys still swear by Isky's 400-JR solid (0.400 lift, 244-degrees at 0.050, 111-degree LSA). They fit original '39-'53 blocks, French blocks, and (perhaps the ultimate evolution) Ferguson's new aluminum block. 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. Four carbs on a properly designed intake manifold offer the best distribution short of today's dry EFI systems. What kind of power are these Arduns putting out?

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. Thanks ! A step by step book on how to identfy and rebuild a ford flatheads. Anyone know of any updates? Many hard-core guys still swear by Iskys 400-JR solid (0.400 lift, 244-degrees at 0.050, 111-degree LSA). Making power with a flathead is a fine balancing act, juggling the higher thermodynamic potential of raising compression against improving airflow through the combustion chamber. Baron, Edelbrock, Sharp (Wilcap), Navarro, and Offenhauser make both old-style heads as well as improved new configurations. 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.

Valves are 1.875 inches in diameter on the intake side, 1.5 on the exhaust. French blocks are about 30 pounds heavier than a standard flathead, which is a good indication of better metal and thicker walls. At around the same time, old-time hot rods gave way to modern musclecars and street machines. This encouraged the old-time flathead parts guys (or their sons) to start repopping the old parts. He was basing his calculations on the assumption that a coefficient of friction of over 1.0 could not be achieved. 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. Fast-forward nearly half a decade. Sponsored Links (Register now to hide all advertisements). 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. The times they were a-changin', and change was happening fast. That should get any hot rodders beat to quicken and pique his curiosity. Back in the day, four-barrel carbs had barely been invented. I'm not sure but casting aluminum MIGHT be a simpler process than casting iron. Ultimately, you can move up to one of Cornhusker Engineering's custom front cover and late-model water-pump setups. Tony Baron says that a good-running flathead should have no less than 0.400 lift and about 250 degrees duration at 0.050-inch tappet lift. 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.

I've sold Don my 409 Chevy to Flathead aluminum water pump kits for years. One solution is adopting a small-block Chevy damper. Copyright 2000-2009 Jelsoft Enterprises Limited. Traditionalists can go with Vertex or Mallory mags, while modern guys may want to move up to MSD or Mallory electronic distributors. But thanks to the efforts of several hot rodders and land speed racers, especially Don, the coveted conversion kits are readily available and much improved over those first heads built in the '40s and '50s. Earlier 3 1/16-inch-bore blocks will only go 0.090-over. After 1953, flathead production continued in other countries, most notably in Europe, where the engine continued to be used in French military vehicles through the 90s. Al moved to So Cal with his family from Oklahoma in the 30s and started working in shops and garages. You need lots of timing to make a flathead run.

There are several reasons for developing a new aluminum block for the Flathead. He bought the entire French stock, and at last count still has at least 500 blocks, 120 complete engines, and over 2,000 rods. Flatheads need high compression because they dont breathe. While Orosco wanted the heads to be as exact a replica as possible"He would be at the foundry getting the shade of the aluminum in the valve covers just right," Don saysFerguson was less interested in the cosmetics and more concerned with re-engineering the heads for maximum performance. Story and Photos by Zac Parks Check out more from Zac on his Instagram Account: @wiredcustoms.va When shopping for the right Flathead for your traditional Hotrod, knowledge is power. Navarro High Dome Heads are designed for special high performance applications. There is also an ugly governor mounting boss on the left-rear of the block that many rodders prefer to machine off. The heads come complete with Isky valve springs, 1.5-inch diameter stainless steel valves, adjustable push rods, lifters, custom head gaskets and a pair of exhaust flanges. 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. Also, what does "wet jackets" mean? 225: Hooligans In Hot Rods Getting Hamburgers, Do Not Sell or Share My Personal Information. 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. https://fordmanualblog.wordpress.com. The flatheads compression ratio is well suited to supercharging, and besides, what could be more hot rod than a blower poking through the hood? 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. Newly Engineered Flathead V8 Block - Motor City Speed Equipment - Automotive American Newly Engineered Flathead V8 Block - Motor City Speed Equipment Advertisements Googling around as you do I initially found the story of Mark Kirby's newly engineered Flathead V8 block on the Coker Tyres website This is a quite old story from back in 2010 Kop This lateral flow severely restricts flathead breathing capability, although it does promote what todays high-tech engineers term swirl and tumble, which enhances fuel mixing and combustion. Learn how your comment data is processed. Cams like this with good aftermarket heads are capable of producing 200 hp and 240 lb-ft naturally aspirated, and over 300 hp and 350 lb-ft with a blower.

La Crescenta, CA 91214 "You can grind the cam to get the lift and duration you want," Don says. The block, heads, intake manifold and water pumps are made out of aluminum, making this a very light alternative to its cast iron brethren. Tom Roberts new two-piece crossflow utilizes the latest in airflow technology. But, he says, most of his Ardun-related business is for hot rodders, not racers. 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. H&H Top Dead Center T-shirt is printed on 100% cotton. I wish I could have stuck around for the next couple of years.
