The real enemy of the Y-block was its displacement limit. The 292 cu in 4. Beginning in 1982, the 302 5. This can be checked without removing the heads. A complete assembly sequence is also laid out for readers to follow with how-to descriptions and illustrations of all the minor details that ensure a successful build.
Bottom row 1 st bolt on the left. The company had designed the Y-block for a 1953 introduction, but a shortage of nickel due to Korean war needs prevented the company from manufacturing the engine in sufficient quantities. Another issue seen is the front cam bearing installed cocked in the bore.

The following lists will help you identify the parts on your engine. Most 292 and 312 blocks were cast at the Cleveland foundry. Regarding the ports, not being a Y-block expert all I can say is they would almost certainly be the smallest available, since that is what you would want on a truck engine in order to lower the power band. Your hub for horsepower Get first access to hit shows like Roadkill and Dirt Every Day Join free for 14 days now The Ford Y-block V-8 was never intended to be a high-performance engine in the first place.

Important upgrades in the 289 occurred for the 1965 model year beginning in August 1964. On high lift cams this glob can be higher than the base circle of the lobe, which can do damage. Performance parts, new and used, are becoming more and more available and can also be fabricated. If these bolts are too long they can contact the front cylinders doing extensive damage. For 1965, the 289-4V engine went from sharing dished pistons and the same compression ratio to 10. It also was used in the Ford Fairlane as well as several models of the Ford Station Wagon. Like the later and better-known but even more short-lived , its block's deep skirts gave the block the appearance of the letter Y from the front.
Bottom row 4 th bolt from the left last one on the right. The added expensive of a 4v Holly should have warranted the small expense of dual exhaust. Bottom row 2nd bolt from the left. . Cylinder heads on the Y have always been a point for discussion. It came in 239ci 256ci for Mercury , the same displacement as the old flathead V8 but with a bigger bore and a shorter stroke 3.
And, since all other internal components are the same this gives you a 292. The 312 remains popular, especially for 1957 Ford and Mercury model devotees. Lots of engines gets swapped over the years.

Rod caps are carefully fitted and torque to specifications one at a time along with a rotational check.
Although I get into casting identification elsewhere in this book, valve-cover style and air-cleaner color identified Ford engines prior to 1966. And torque is the kind of power you want on the street. Carroll Shelby began his two-seat Cobra production with the 260 topped with a Cobra high-rise manifold and Holley carburetion. These desirable heads have larger ports, valves, and chambers, which make them a great budget swap. Ring sets are sold separately. Jeff Zurschmeide is a freelance writer from Portland, Oregon. It's essentially a durability upgrade.
Its development was in response to the sales success of the competing and engines introduced in their respective 1949 models, as well as the need for larger and more powerful truck engines. And this difference in cam profiles probably is the reason for only 11 horsepower diffference. There is a bolt pattern. Connect timing light high voltage lead to wire going to Number 1 spark plug and the appropriate low voltage leads to the battery connections per timing light instructions. V '65-'70 240 155 4400 4.
