Unfortunately, the Cleveland engine was introduced at the end of Detroit's muscle car era, and the engine, in pure Cleveland form, was very short lived. It did continue on as a low compression passenger car and truck engine in the form of the 351M and 400M, which in their day, offered little in the way of excitement.
The 400 was intended as a replacement for Ford's aging big-block designs. The block's architecture borrowed heavily from the Cleveland, including the bore spacing, but 1.09 inches of additional deck height were added to allow a 4.00-inch stroke and the potential for plenty of torque.
The 400 CID Ford engine does not fit nicely into the small block/big block description. It is based on the 335 family of engines. This includes the 351C (Cleveland) and 351M (Modified). See Wikipedia, they have an excellent article.
Is the Ford 400 a good engine? If you keep the Ford 400 maintained, it will last as long as any other engine – upwards of 200,000 miles – until you have to rebuild it.
The Ford 400 engine was based on the 351 Cleveland but had a half-inch longer stroke than the 351 Cleveland. The 400 had "square" proportions, with a 4.0 in (102 mm) bore and stroke. Ford called the engine a "400" but in actuality it displaced 402.1 cu in (6.6 L; 6,590 cc).
The 292 cu in (4,778 cc) Y-Block was also introduced in 1955. The 292 shared the 3.3 in (83.82 mm) stroke of the 272 but with a larger 3.75 in (95.25 mm) bore. It was used in the Ford Thunderbird, 1959-60 Edsel, Mercury, and some high-end Ford cars.
The most reliable Ford diesel engines are the 7.3L Power Stroke V8 and the 6.7L Power Stroke V8. The 7.3L is most reliable in longevity, often reaching 300,000 to 500,000 miles with proper maintenance. The 6.7L is most reliable at higher towing capacity, with an upper gooseneck limit of 40,000 lb.
360 Truck. The 361/360, of 360.8 cu in (5.9 L) actual displacement, was introduced in 1968 and phased out at the end of the 1976-year run; it was used in the Ford F Series trucks and pickups. It has a bore of a 390 (4.05 inches (102.87 mm)) and used the 352's 3.5 in (88.90 mm) rotating assembly.
6.6-Liter Engines: The Ford 400 engine (6.6-liters) was a part of the 335 Ford engine family and was built to replace the 390 FE engine which was growing older and becoming harder to get to pass growing emissions regulations in the United States.
The 400 also featured larger (Windsor sized 3.00 inch with Cleveland cap register) main-bearing journals and had "square" proportions, with a 4.0 in (102 mm) bore and stroke; it therefore displaced 402 cu in (6.6 L), making it the largest small-block V8 made at that time.
The M stands for Modified, but not in a good way. It's set up for smog by having low compression and an EGR valve. The 351C-2V made between 1970 and 1973 is the best 351 engine (in stock form).
In fact, the only functional difference between the 351M and 400 is the crankshaft and pistons. Ford did use slightly different components in the 351M and 400, such as harmonic balancers, camshafts, and valve springs, but functionally, the engines were identical except for the crankshaft and pistons.
Venomous strike: The all-new 2020 Mustang Shelby GT500 will produce 760 horsepower and 625 lb. -ft. of torque, making it the most powerful street-legal Ford ever – with the most power- and torque-dense supercharged production V8 engine in the world.
The principal reason Edsel's failure is so infamous is that Ford did not consider that failure was a possibility until after the cars had been designed and built, the dealerships established, and $400 million invested in the product's development, advertising and launch.
The 6.4 Powerstroke came after the 6.0 Powerstroke, which was widely panned for its problems and poor performance. The issues with both of these engines eventually led to the end of the working relationship between Ford and Navistar and led to Ford designing its next diesel engine in-house.
From 1977 to 1982, the M-block (351M/400) V8 engine was a mainstay of Ford light truck powerplants. During that period, the M-block 400 was the largest engine available in any Ford 4x4 truck. In the 1978 and 1979 model years, the 351M and 400 were the only engines offered in Ford's new, full-size Bronco.
6.6L V8 (400 CID): The 400 was essentially a 351M with a longer stroke, offering more torque at lower RPMs, making it ideal for towing and heavy-duty applications. It produced around 158 horsepower and 277 lb-ft of torque.
The Ford 427 SOHC (Single Overhead Cam) V8 is one of the most iconic and rare engines in automotive history. It was developed for racing and used in the legendary Ford GT40, which competed in endurance racing events like the 24 Hours of Le Mans.
The 352 was Introduced in 1958 as part of the “Interceptor” (high performance) line of FE engines. The 352 has an actual displacement of 351.9 CID. It is a stroked 332 with 3.50″ stroke while retaining the 332's 4.00″ bore.
The Ford 360 engine is a V8 engine created between 1968 and 1971 with two barrels had 215 horsepower at 4,400 rpm and a max torque of 327 at 2,400 rpm.
