Displacement was increased in 1955 to 272 cu. The profile of the manifold is low for hood clearance. One guy asked if I had to do anything special to make it run right and I told him I had to fill the radiator with salt water!! One of the most common decisions one faceswhen running a Y Block is what sort of induction system to use. It was a time of optimism, consumerism, and a burgeoning American economy. Note that it is a single plane manifold, a design probably selected for its low profile, useful in inboard boat installations. I believe this manifold is meant for large port heads.
These features included full pressure oil filtration, valve guide oil diverters, shaft rocker arms, a single water pump, counterweighted fuel pump concentric, oil trough for timing chain oiling, and staggered oiling at the connecting rods. Over the next few years, the only passenger-car Y-blocks available were lower-horsepower versions of the 292, which eventually bowed out in 1962 in cars but continued a while after that in truck applications. Homemade intakes arealso a possibility here and some Y Block users have fabricated tunnel rams withsome success. Cautions on camshafts are four-fold. Fourth, and this is important, remember that mushroom lifters are the first items installed in a Y-block rebuild, then the cam! V8 1959-1960 cars and trucks.
That was one way to escalate the advertised-horsepower stakes. If the engine is disassembled, check the casting number on the main cap. Cleveland Foundry parts have an F surrounded by a semicircle to identify their source. The most desirable are the bigger 292 and 312 versions, although a 272 with a few improvements will do. I include this picture to give an example of other possibilities the Interceptor manifold could support.
It will accept modern Holley, Carter, and Edelbrock carbs. In order to gain access to all of the runners, especially the transition points, he has machined the top of the manifold, opened the runners, and then fitted an aluminum plate to the flat surface. It can be recognized by the small 4v mounting flange. Although all Y-Blocks use the same connecting rod bearing with 2. Ford was back in the game with the larger versions of its Y-blocks by the mid-1950s.
Note how both carburetors are centered over the runners. Since brand-new engines take some time to trickle down to the wrecking yards where hot rodders mined for transplant horsepower, use of Y-blocks in hot rods continued well into the 1960s. These included a mechanical camshaft and 14 mm sparkplug with a washer that would later be replaced in 1955 by a tapered seat 18 mm spark plug. Blue Thunder This is probably the best bet for a Y Block performance manifold. Edelbrock M254 This manifold was intended for the 1954 Mercury 256, which had smaller ports than the 55 and 56 Y blocks.
I miss the sound since I sold mine. Offenhauser and other companies quickly set about to make cast-aluminum bellhousing adapters to attach 272-292-312 motors to traditional Ford transmissions, easing the transition from a Flathead to an overhead. Its ports match for 55 and 56 style heads. The intake on Y-block engines is somewhat unusual, in that the ports are laid on top of each other-in other words, there are two groups of two ports on each side and each group is not side by side but over and under. Mounting a Y-block in your street rod chassis is not a problem, either.
Edmunds 3x2 Edmunds was a quality manufacturer of speed equipment from the flathead V8 days, along with Edelbrock and Navarro. It may be the best flowing 3x2 manifold. Third, the oiling for the rocker arms lack of such is one of the original urban legends about Y-blocks come from a passage leading upward from the center camshaft journal. The Ford Y Block 239 engine was a Ford production V8 that had a number of features not seen before on V8 engines. The 312 had a 3. Identify Your Y-Block Identifying Your Y-Block The Ford Y-Block was introduced in 1954.
The single plane 4v manifold offeredby Jerry Christensen offers drag strip proven performance. You want a stick with no more than 108-110 degrees of lobe separation for an engine with around 9:1 compression. At compression ratios of 8. Beyond this, thereare other possibilities that you might choose for your Y Block, some of whichwill be covered in this discussion. In 1956, they added an oil singer at the back of the crankshaft. V8 1958-1959 cars and trucks to April '59.
Using this manifold on the street would require fabrication of a water manifold for coolant. Originals can be found, and most of the Thunderbird restoration supply catalogs have a current reproduction of this. Production continued at the Cleveland foundry while the Y-Block was installed in cars through 1962 and trucks through 1964. The Ford Y Block 239 Cubic Inch engine was included with Ford trucks from the years 1954 to 1964, Ford cars from 1954 to 1962, and the Ford Thunderbird during years 1955, 1956 and 1957. Its flow and power production have been proven in dyno tests. I had to fab my own necks to the radiator, but the installation wasn't too difficult at all and the results were well worth it.
