These Scat rods are designed for a 2. Caveat emptor let the buyer beware is the phrase to keep in mind. Step 3: A boring bar micrometer is used to set up the cutting tool to the exact size. It ensures that the block mating surfaces are flat, smooth, and parallel to the mains and crankshaft; it also results in proper head gasket seal. Does balancing make any difference? The second design of the legendary Ford flathead, the 1939-48 flathead engines block moved to a 24 head retention stud design. Some force is needed, but take care not to damage the port.
On the street, they can cause an engine to run a little hot, so they are used primarily for racing. Early Ford V-8 Sales in South Carolina also makes a starter. Flathead blocks are heavy, and care is needed when moving them. Step 5: With plenty of Sunnen honing oil, Mike makes multiple passes: at the bottom of the bore, at the top, and in the middle. Mallory also offers electronic ignition components. Depending upon the year of your engine, new cast-iron and even polished aluminum pumps are available from Bob Drake and Speedway.
This is only really necessary for race engines, however. Van pelt has good parts. Step 2: Grinding wheels become dull or glazed with use, and their cutting surfaces need to be constantly dressed cleaned. Those grinds were within tolerance but were not my best work. Plugs and Plug Wires Choosing plugs for your rebuilt flathead might necessitate some trial and error as you break in the engine and ascertain what heat range is suitable for your location and driving style. They supply everything you need to rebuild a stock 97 carburetor, as well as brand-new Stromberg 97s built to original specification with key improvements. The generators look original, have a one-wire hookup, and produce 60 amps at idle and 75 at road speed.
Step 7: The thread of the screw is coated in Seal-Lock Fluid Weld from Cylinder Head Supply and then screwed into the block using a socket and extension. Reds headers has great parts and great prices. Both are available with either plain or chrome finish. Pressure sealing the block is essential. The third and final design of the legendary Ford flathead, the 1949-53 model featured a bolt-on bellhousing and a relocated distributor.
Be sure to take plenty of photographs of your block and any little identifying marks it may have. The system is then back-pressured and drained completely before the procedure is repeated on the other side of the block. Then, remove a little metal from each, until all of the pistons weigh the same as the lightest piston and all of the rods weigh the same as the lightest rod. Step 6: When all the bob weights are correctly installed, the computer calculates all of the information necessary to balance the crank. Step 9: A carbide burr tool grinds away the remainder of the screw, leaving it flush with the port wall. The three cams are the Classic Thumpr for street performance, the Mutha Thumpr for street and strip, and the Big Mutha Thumpr for high-performance engines only.
You can either have your original factory starter rebuilt and paint it or dress it up with an accessory cover, or you can opt for a new stock or compact Powermaster unit. A keen eye and an understanding of parting lines and core shift are imperative, so you are not fooled by what does and does not constitute a crack. They came in at approximately 403. The air-conditioning kit from Vintage Air is traditional in appearance, with old-style V-belts. Flatheads can be full of cracks, so seek expert advice about reparability. Similar to a Blanchard grinder, the Storm Vulcan uses a fixed stone headstock to parallel-grind material with an infinitely controlled hydraulic table, allowing for any degree of surface finish.
It has the looks to demand attention, particularly because the flathead has a low profile, so the stacks can add some impressive and much-needed underhood height. If you are going for a stock rebuild, shop around for pistons and rings. This sharpening tool is used to dress the grinding wheel. However, good sources are available for connecting rod bearings. It also sells kits for headers, trans mounts, generators, fan pulleys, and heads. He moves the adjustable cutter in his left hand up and down the surface of the wheel.
Step 3: The guide that registers on the hole for the valveguide is slipped into the block. Ford used some pretty hard seats in these. Timing is adjusted on the side, just like the original Ford 21A distributor. Superchargers The flathead can have a visually low silhouette. Don't buy pistons, rings or bearings until your parts are back from the machine shop. These are not returnable for credit. Ford service bulletins give an acceptable weight of 451 to 455 grams; with a little care, all of the rods can weight exactly the same.
The gauge indicates how much the hole needs to be bored to return it to exact size and roundness. Specialty sleeves for high-performance and race engines that require harder ductile iron are available from Los Angeles Sleeve Company. Step 3: Using a small handheld electric drill, Mike drills through the port wall, being careful not to drill too far or to allow the drill chuck to make contact with the block. Factory specs are parameters that suffice for mass-production engines taking into account time, labor, materials, and so on. This shows the leveling fore and aft, but you need to check left to right also.
Be sure to record all of the weights for the rods, pistons, and associated components; they will be needed later when you balance the crank. If you build two engines to factory specs, there will always be variances between rod and main bearing clearances, variances in piston clearances, deck height differences, valve-spring pressure differences, and intake and exhaust port and chamber volume differences. A matched set of parts can be a good way to go. Photo Courtesy Speedway Motors Offenhauser offers a cast aluminum adapter for bolting a 3-, 4-, or 5-speed Chevy manual transmission to the back of a 1932—1948 Ford block or a 1939—1950 Merc. Although the crank itself is put in the balancer, bob weights are installed to replicate the rod and piston assemblies.
