Scat offers affordable cast Pro Stock cranks through 4.375-inch stroke, with either 2.00- or 2.138-inch rod journals. Here, the valve spring is compressed so that the locks (valve spring retainers) can be installed. Speedway Motors offers pumps with sealed bearings that do an even better job in both early and late configurations. Large-diameter, unshrouded valves combined with a proper combustion chamber configuration and piston design are needed to promote the proper transfer area from the flathead's valves to the far end of the chamber over the piston tops. This improves airflow, but the resultant effective combustion-chamber-volume increase lowers the compression ratio, in turn decreasing horsepower and fuel economy. With the heavy-duty versions being most susceptible to heat issues, the first attempts at separating exhaust heat were designed for the truck market. Flatheads began to come back, and prices of swap-meet stuff skyrocketed. The company they formed to produce these heads was named "Ardun," an acronym derived from their last name. The clearance between the top of the piston and the roof of the combustion chamber is .063 inch, which is suffi cient and confirms the previous calculations. At one end there are restorers who insist on putting everything back to exact original condition. The best balance has been the subject of debate for over 60 years. Fortunately, a wide variety of adapters are available to mate the venerable motor to today's automatic and manual transmissions. To begin the porting process, Dykem was brushed onto the exhaust flange. Free shipping. Be sure that you do not let the tool get away from you and score the manifold. Length, Each. As mentioned, there were two things to remember about this era EVERYONE was trying something new, and heat was the flatheads main enemy! In addition, an original (short) truck oil pickup was required to match the stock truck pan. Besides, porting is something that you can kind of tackle yourself. Again, the intake is marked and then the material is cut away very carefully. Joe passed away in 1995 and four-bangers have become something of a niche in the hobby, but they still have a high cool factor and a high potential for making power. There was a 226ci engine used in lots of cars over the years with a max power rating of . This reduced heat absorption but didnt do much for performance, as the airflows path was still quite restrictive and convoluted. Check the crank at every stage of the tightening process to make sure that it turns freely. As you have seen, finding a good usable original block is tough, even for a mild street engine. Complete Flywheel and V8 Ford clutch plate, Cragar Four Port Cylinder Head for Ford B Engines. 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. Reams have been written about porting the flathead, because in factory form its a very asthmatic engine. 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. ", Among this herd of sheep, a few original hot rods were brought out of retirement, complete with gennie flatheads as the powerplant. 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. Its not a good idea to experiment on the good block you intend to use because you could make a mistake and end up worse than before you started. Made of 3/16 inch cork and rubber. Melling still makes a high-volume oil pump (PN M-15). Small-block Chevy valves remain popular, but with reduced-base-circle cams they may be too short to permit proper lash adjustment. However, this is a blueprinted race engine. Compression ratio is 9:1. If it boils, steam pockets form, and when you have steam, you'll get cracks. Machining required to fit Model A or B cranks. This produced a 418-inch stroke that, when coupled with a 3516-inch bore, results in a 284-ci engine. Some say that the NOS French block is the way to go, and in some ways it is. Four carbs on a properly designed intake manifold offer the best distribution short of today's dry EFI systems. The flathead blocks to get are those with a 3 3/16-inch bore. The flathead Ford still enjoys a strong following and parts are readily available to rebuild one and keep that flathead-specific exhaust sound alive. Stromberg parts as well as our own Drake Made items, many Ford authorized! Tom Roberts' new two-piece crossflow utilizes the latest in airflow technology. For Rays engine, H&H chose an original 4-inch Merc stroker crank that had been offset-ground 1/8 inch. We have thousands of Flathead Ford, Y-Block and Model A exhaust parts, engine parts, and speed parts. Reserve these early blocks for collector cars due to their inferior head-retention and bearing design; speed equipment availability for them is also severely limited. Possibly one of the rarest OHV conversions is the Stephens. Not all intakes have this feature.

Interestingly, part of that room is devoted to engines that went beyond the simple flat-head design and utilized many of the various over-head conversion units that were available. Ultimately, you can move up to one of Cornhusker Engineering's custom front cover and late-model water-pump setups. Of course, this modern stuff requires a 12-volt electrical system. Because of the way the flathead was designed, the two inside exhaust ports thread through the middle of the block and heat it up before they are siamesed into one rather than two exit ports. A flathead engine, also known as a sidevalve engine [1] [2] or valve-in-block engine is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine . Most builders convert the stock oil system to a full-flow design with a modern, remote-mounted oil filter. Relieved blocks must have the reliefs filled to use Ardun heads. I have a 1942 Ford 6-cylinder flathead engine that my brother would like to sell. With no rocker arms, a flathead's total lift must be generated entirely by the cam lobe. According to Mike, something with a good rebuild similar to Theresa Spurlocks engine (see Chapter 9), Navarro heads and intake, an 8.25:1 compression ratio, and a pair of Stromberg 97s should produce around 160 hp. That might involve time and disappointment as blocks are rejected. 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 pistons are installed following the piston installation procedure outlined in Chapter 8. We thought it would make a great highlight for our RodAuthority.com readers.

Offset-ground means that the original 2.138-inch big end, or rod pin, journals were reground 1/8-inch offset and smaller to accept 2-inch bearings. The exhaust then had a short trip out to the exhaust manifold, which reduced heat transfer greatly. Water jacket holes are fitted with a copper ringlet. There is also an ugly governor mounting boss on the left-rear of the block that many rodders prefer to machine off. Early and late distributor styles can be interchanged by using the corresponding front engine covers and cam drive.
