and Fairlane. Although sometimes called the "Windsor" by enthusiasts, Ford never used that designation for the engine line as a whole; it was only adopted informally well into its run to distinguish the version from the "Cleveland" version of the 335-family engine that had the same displacement but a significantly different configuration. The designations for each were derived from the original locations of manufacture: Windsor, Ontario and Cleveland, Ohio. From 1962 through the 1990s these engines were marinized by various companies (255ci/4.2L excepted). The small block remains available for purchase from Ford Performance Parts as a crate engine.


Overview

The small-block engine was introduced in the 1962 Ford Fairlane and Mercury Meteor cars. Displacing , it was designed to save weight, using thin-wall casting with a block that does not extend below the centerline of the crankshaft. The engine uses a separate aluminum timing chain cover, which differentiates it from the later 335-series Cleveland engines that use an integrated timing cover. All Ford Small Block engines use two-valve-per-cylinder heads, with "2V" and "4V" designations indicating the number of barrels (or venturi) in the
carburetor A carburetor (also spelled carburettor) is a device used by an internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the venturi tube in the main meter ...
. The valves are in-line and use straight six-bolt valve covers. Coolant is routed out of the block through the intake manifold. The design was soon bored to and again to , then stroked to , settling on the most common displacement offered until the engine's retirement in 2001, nearly 40 years after the basic block design debuted. Two additional displacements were produced during the engine's history. A model (stroked from the 302) was offered beginning in 1969 and continuing until 1996. The 351W (so identified to distinguish from the 335-series Cleveland 351C) uses a taller block than the other engines in the series to avoid excessively short connecting rods. And for a brief time in the early 1980s a version with a smaller bore diameter that displaced was produced as Ford struggled with emissions and fuel economy. In response to the

, Ford engineers developed a new racing engine from the small block. The first attempt mated a tunnel-port head to a 289 cu in block, but the displacement proved to be too small to deliver the desired power. The next iteration of the engine mated an improved head design to the 302 cu in block, producing the famous " Boss 302". The heads from the Boss 302 became the production heads on the 335-series Cleveland engines, which used the same bore spacing and head bolt configuration as the small block engines. As the 1980s drew to a close, Ford began the design of a new OHC V8 to replace the venerable small block design. The Modular 4.6 L OHC V8 debuted in the 1991

Design changes

All of the July 1961 through August 1964 221-260-289 engines used a five-bolt bell housing, with all 221s and 260s being of this configuration, but the 289 changed to the six-bolt arrangement at this time - the change was made due to transmission utilization issues i.e. the need for larger-diameter clutches, for example. The block mount pads and the cylinder wall contour of the 221 and 260 engines changed in January–February 1963 with the introduction of the 289 variant – all 221 and 260 engine blocks up to this time featured 'corrugated wall' construction with two freeze plugs on the side of each bank and engine mount hole pitch distances of 6 inch. All three block variants from this point on featured the straight wall method of construction, three freeze plugs and an engine mount hole pitch distance of seven inches. The corrugated wall method of block construction had caused cleaning difficulties in the foundry from day one and a change was phased in.

260

The second version of the Fairlane V8 was given the name Challenger, and was introduced during the middle of the 1962 model year (March 1962). It had a larger bore of 3.80 in (96.5 mm), increasing displacement to . Compression ratio was raised fractionally to 8.8:1. The engine was slightly heavier than the 221, at 482 lb (219 kg). Rated power (still SAE gross) rose to at 4400 rpm, with a peak torque of at 2200 rpm. For the 1962 and 1963 car model years, the valve head diameters remained the same as the 221, but for the 1964 car model year, they were enlarged to 1.67 in (42.4 mm) (intake) and 1.45 in (36.8 mm) (exhaust) – this was an economy measure so that both 260 and 289 engines could use the same valves. Rated power was not changed. In 1963, the 260 became the base engine on full-sized Ford sedans. Later in the model year, its availability was expanded to the

For 1965, the compression ratio of the base 289 was raised to 9.3:1, increasing power and torque to at 4,400 rpm and at 2,400 rpm, respectively. In 1968, the two-barrel was reduced to .


A-Code

In 1965 the four-barrel version was increased to 10.0:1 compression, and was rated at at 4,800 rpm and at 3,200 rpm. The 289-4V was also the engine for the first Australian Ford Falcon GT, the XR Falcon GT.


Production Numbers

Around 3,500,000 289-2V and 289-4V engines were made at Cleveland Engine Plant 1 (CEP1) in 1963-1967 and 800,000 289-2V at Windsor Engine Plant 1 (WEP1).

of cars so equipped). Oddly, this engine was introduced in 1963 as the only 289 engine available in the intermediate Fairlanes. Lesser-powered cars had the 260 engine in that year. Starting in June 1964, it became an option for the Mustang. The HiPo engine was engineered to increase performance and high-RPM reliability over standard 289 fare. It had solid lifters with hotter cam timing; 10.5:1 compression; a dual point, centrifugal advance distributor; smaller combustion chamber heads with cast spring cups and screw-in studs; low-restriction exhaust manifolds; and a bigger, manual-choke 595 CFM

(the standard 289-4V was 480 CFM). The water pump, fuel pump, and alternator/generator pulleys were altered, fewer vanes, extra spring, and larger diameter, respectively; to help handle the higher engine speeds. Even the HiPo's fan was unique. Bottom-end improvements included a flaw-free selected standard block, thicker main bearing caps and crankshaft damper/balancer, larger-diameter rod bolts, a crankshaft made from 80% nodular iron as opposed to the regular items at 40%, all were checked for correct 'nodularity' by polishing an area of the rear counterweight and comparing that surface using a magnification arrangement against a picture datum, increased crankshaft counterweighting to compensate for the heavier connecting rod big ends, the increased external counter weighting at the front was split between the crankshaft damper and a supplementary counterweight place adjacent to the front main bearing journal (all designed to reduce the 'bending moment' in the crankshaft at high-rpm), all for high-rpm reliability.

302 4-Bolt Main bearing caps


GT-40

Ford designed a new 302 block for the 1967 GT-40, due to a new regulation which limited engine displacement to 5.0 litres. Ford was able to arrive at the 302 displacement by an extra eighth-inch of piston travel to the 289 Hi-Performance V8. The block featured heavy-duty, four-bolt main bearing caps and pressed in freeze plugs. This engine was topped with Gurney-Weslake aluminum heads. About 50 blocks were made.


Trans-Am 302

Ford's new 302 "Tunnel-Port" engine was originally envisioned as the secret weapon for the 1968 Trans-Am season, which would bring them a third Championship win. Starting with a 1967 GT-40 block, Ford topped the engine with a new head design. The new heads were based on the design of Ford's NASCAR 427 heads. The intake ports were straight, instead of snaking around the push rods. The push rods actually went through the center of the ports (thus the name "Tunnel-Port"). This configuration also enabled larger valves to be used. The 302 tunnel-port motor was topped off with an aluminum dual quad intake. Shelby dyno sheets showed this engine was capable of producing horsepower in the 440 to 450 range, and operated through a very high rpm band (8000+).


Boss 302

The Boss 302 was a chief engineer Bill Gay-inspired and Bill Barr-enacted performance variant of the small block, putting Cleveland-type cylinder heads at their then present stage of development (that's very large valves which were only used in 1969 due to the design being 'frozen' at this specification so production could commence) on Ford's 1967 GT-40 racing block to improve rated power to . According to some reports, the canted-valve, deep-breathing, high-revving engine could produce more than , although as delivered, it was equipped with an electrical revolution limiter that restricted maximum engine speed to 6,150 rpm. A strong bottom end, thicker cylinder walls, steel screw-in freeze plugs, race-prepared crank, special HD connecting rods, and Cleveland-style forged pistons kept the engine together at high speeds. The key to this engine's power was the large-port, large-valve, quench-chambered, free-flowing heads. The

for two consecutive years, using various versions of the Ford big-block engine. In an attempt to reduce the high speeds, the organizers of this race capped the engine capacity in 1968. Ford consequently returned to the MKI GT40 (originally using the Windsor 289), but had now increased its capacity to meet the new rules. Since Ford had ruled that the GT40 engines must have a direct link back to its production cars, the 302 was adopted in domestic manufacturing. In 1968, the small-block Ford was stroked to , giving a total displacement of . The connecting rods were shortened to allow the use of the same pistons as the 289. It replaced the 289 early in the 1968 model year. The most common form of this engine used a two-barrel carburetor, initially with 9.5:1 compression. It had hydraulic lifters and valves of (intake) and (exhaust), and was rated (SAE gross) at at 4,600 rpm and at 2,600 rpm. Optional was a four-barrel version rated at at 4,800 rpm. The 302 was manufactured in Windsor from 1968 to 1978. Ten years of manufacture was punctuated by several design changes, some small or larger. In 1970, the manufacturing of the engine was moved from Windsor, Ontario to Cleveland, Ohio. Along with the move came most changes that stayed with it for the remainder of its life. These were longer valve stems with rotating lash caps, bottle neck type rocker studs for a positive stop nut arrangement and a longer pushrod to correct valve train geometry. The water pump borrowed from the 351 Cleveland, with a few minor alterations to the casting, allowed the use of a left hand water inlet. (this improved water circulation in the radiator to a more cross-flow direction). This change also necessitated the need for a harmonic damper change to move the timing marks to the other side of the front timing cover and a change to four bolts holding the crank pulley rather than just three.

GT-350

For 1968 only, a special high-performance version of the 302 was offered for the Shelby GT350. The main features included: an angled, high-rise aluminum or iron intake manifold, a larger Holley four-barrel carburetor, and bigger valves of intake and exhaust. It had a longer-duration camshaft, still with hydraulic lifters. The heads had special close-tolerance pushrod holes to guide the pushrods without rail rocker arms or stamped steel guide plates. The combustion chambers also featured a smaller quench design for a higher compression ratio and enhanced flow characteristics. Additionally, high-flow cast exhaust manifolds similar to those on the 289 Hi-Po K-code engine further improved output. Heavy-duty connecting rods with high-strength bolts and a nodular iron crankshaft were also included in this package. Rated power (SAE gross) was estimated at at 6,000 rpm and at 3,800 rpm. The package, which cost $692 including some other equipment, was not popular and did not return for 1969. This engine was not a factory engine. Rather, like all Shelby Mustang engines, it was modified by Shelby American in their capacity as a vehicle upfitter. This special engine is well documented in the Ford factory engine repair manual for 1968 Mustangs and Fairlanes. The block was made in

The Mexican 302 block was produced through to the mid-1990s and even showed up in Ford cars, trucks, and vans throughout the 1970s and early 1980s (Mexican-made 302 engines were often used by the USA car plants when CEP1 could not produce enough engines and many Ford replacement engines were Mexican). Mexican blocks were not made from a high-

CAFE standards led to the creation of the version for the 1980 model year, essentially a 302 with the cylinder bores reduced to 3.68 in (93.5 mm). The 302 was to be phased out and the 255 was to be an interim engine which would remain until the new V6 was in production - a quick fix. Rated power (SAE net) was 115-122 hp (86-91 kW), depending on year and application. Cylinder heads, which were specific to this engine, used smaller combustion chambers and valves, and the intake ports were oval whereas the others were all rectangular. The only externally visible clue was the use of an open-runner intake manifold with a stamped-steel lifter valley cover attached to its underside, reminiscent of previous-generation V8 engines, such as the Y-block and the MEL. It was optional in Fox-chassis cars including the Mustang and corporate cousin Mercury Capri, Thunderbird, Fairmont, and standard equipment in the Ford LTD. Some variants (i.e. Mercury Grand Marquis) were fitted with a variable-venturi carburetor which were capable of highway fuel economy in excess of 27 MPG. Due to its dismal overall performance the 255 was dropped at the end the 1982 car model-year with 253,000 units manufactured - 302 production continued and the plans to phase it out were dropped.

s were first equipped with two-barrel carburetors (1982), then a four-barrel Holley carburetor (1983–85). The block was fitted with revised, taller lifter bosses to accept roller lifters, and a steel camshaft in 1985, and electronic sequential fuel injection was introduced in 1986. While sequential injection was used on the Mustang beginning in 1986, many other vehicles, including trucks, continued to use a batch-fire fuel injection system. The speed-density based EFI systems used a large, two-piece, cast-aluminum manifold. It was fitted on all engines through 1988, after which year it was phased out for a mass-air type measuring system in most applications (non-California compliant Panther platform cars retained the speed-density system until the

received the Modular V8 for model year 1991, and the Crown Victoria and Grand Marquis for 1992). The same manifold was used in MAF applications, with the addition of the MAF sensor in the air intake tube. The MAF system continued, with minor revisions, until the retirement of the engine in 2001. Ford offered a performance head that was a stock part on 1993–1995 Mustang Cobra models and pre-1997 ½ Ford Explorers and Mercury Mountaineers equipped with the 5.0 L engine called the GT-40 head (casting ID F3ZE-AA). In mid-1997, the Explorer and Mountaineer 5.0 L heads were revised and renamed GT40P. The GT40P heads, unlike the GT40 heads, had a very well-developed port shape/design which yielded about 200 cfm on the intake side and 140 cfm on the exhaust side without increasing the size of the ports at all from standard E7TE castings, and without increasing the exhaust valve size. They also had smaller 59-61 cc combustion chambers for added compression, and the combustion chamber shape was revised to put the spark plug tip near the center of the chamber for a more even burn. These GT40P heads are considered by many enthusiasts to be extremely efficient. The 302 remained a mainstay of various Ford cars and trucks through the late '90s, although it was progressively replaced by the 4.6 L Modular engine starting in the early 1990s. The last 302 engine was produced for installation in a production vehicle at Cleveland Engine Plant #1 in December 2000, as part of a build-ahead to supply Ford of Australia, which installed their last such engine in a new vehicle in August 2002. The 302 is still available as a complete crate motor from Ford Racing Performance Parts. Applications: *1982–1995

5.6

In 2001, Ford Australia also built some stroked, 5.6 L (5,605 cc, 342 cu in) Windsors with reworked GT40P heads (featuring larger valves), a unique eight-trumpet inlet manifold fitted with a unique throttle body, long-throw crank, H-beam rods, and roller rockers. Used in vehicles known as “T” series Ford Falcons and XR8 Pursuit 250 in their last collaboration (and possibly the last production use of the Windsor small block) in 2001-2002. Vehicles fitted with these stroker engines were sold under the banner of, and only available from dealers under the FTE banner (Ford Tickford Experience). They were produced in conjunction with long standing performance partner Tickford. They produced at 5,250 rpm and at 4,250 rpm. The 5.6 litres of displacement were reached by lengthening the stroke from to .


Truck 302

The Truck Division instigated a pushrod-operated four-valve-per-cylinder, cylinder head conversion in the early 1990s as a means of modernizing/improving and furthering the service life of the Windsor engine. This work was done for Ford by Roush Industries (for US$1 million) and two 302ci/5.0L and one 351ci/5.8 L variants were built and tested. These engines were highly successful, but upper management refused to allow engines so equipped to go into production, stating that to use a cast iron block in a new car (though the 302 remained an engine option in Explorers through MY2001) was no longer acceptable. One of the 5.0 L engines is in use in a hot rod. Various aftermarket manufacturers have also produced four-valve heads for the 302, notably Dominion Performance and Arao Engineering.

The 302 was marinized and offered in both standard and reverse-rotation setups.

, which is a different engine of identical displacement. The Windsor featured a 1.3 in (32.5 mm) taller deck height than the 302, allowing a stroke of 3.5 in (88.9 mm). Although very much related in general configuration to the 289-302 and sharing the same bell housing, motor mounts, and other small parts, the 351W had a unique, tall-deck block, larger main bearing caps, thicker, longer connecting rods, and a distinct firing order (1-3-7-2-6-5-4-8 versus the usual 1-5-4-2-6-3-7-8, a means to move the unacceptable 'noise' of the consecutive firing adjacent front cylinders to the more rigid rear part of the engine block all while reducing excessive main bearing load), adding some 25 lb (11 kg) to the engine's dry weight.

is slightly different, so as to accommodate a larger oil pump shaft and larger oil pump. Some years had threaded dipstick tubes. It had a unique head which optimized torque over high-rpm breathing, frequently replaced by enthusiasts with aftermarket heads providing better performance. The early 1969 and 1970 heads had larger valves and ports for better performance. The head castings and valve head sizes from 1969 to 1976 were different, notably in passages for air injection and spark plug diameters (1969-1974 18 mm, 1975 and up 14 mm). From 1977 onward, the 351W shared the same head casting as the 302, differing only in bolt hole diameters (7/16 inch for 302, 1/2 inch for 351W). Early blocks (casting ID C9OE-6015-B) had enough metal on bearing saddles 2, 3, and 4 for four-bolt mains, and as with all small-block Fords (SBFs), were superior in strength to most late-model, lightweight castings. Generally, the 1969 to 1974 blocks are considered to be far superior in strength than the later blocks, making these early units some of the strongest and most desirable in the entire SBF engine family including the 335-series. During the 1980s, a four-barrel version (intake manifold casting ID E6TE-9425-B) was reintroduced for use in light trucks and vans. In 1988,

ID C9OE-A) featured drilled oil squirt bosses to lubricate the piston pin and cylinder bore and rectangular-head rod bolts mounted on broached shoulders. A number of fatigue failures were attributed to the machining of the part, so the bolt head area was spot-faced to retain metal in the critical area, requiring the use of 'football head' bolts. In 1975, the beam forging (D6OE-AA) was updated with more metal in the bolt-head area. The oil squirt bosses were drilled for use in export engines, where the quality of accessible lubricants was questionable. The rod cap forging remained the same on both units (part ID C9OE-A). In 1982, the design of the Essex V6 engine used a new version of the 351W connecting rod (E2AE-A), the difference between the two parts was that the V6 and V8 units were machined in metric and

units, respectively. The cap featured a longer boss for balancing than the original design. The block underwent some changes since its inception. In 1971, deck height was extended from 9.480 in to 9.503 in (casting D1AE-6015-DA) to lower the compression ratio to reduce NOx emissions without the need to change piston or cylinder-head design. In 1974, a boss was added on the front of the right cylinder bank to mount the air injection pump (casting D4AE-A). In 1974, the oil dipstick tube moved from the timing case to the skirt under the left cylinder bank near the rear of the casting. These details made swapping older blocks from passenger cars with front sump oil pans to more recent rear-sumped

and LTD/Crown Vic Ford cars more difficult unless an oil pan had the dipstick mounted therein. In 1984, the rear main seal was changed from a two-piece component to a one-piece design. Introduced in 1969, it was initially rated (SAE gross) at with a two-barrel carburetor or with a four-barrel. When Ford switched to net power ratings in 1972, it was rated at 153 to 161 hp (114 to 120 kW), although actual, installed horsepower was only fractionally lower than in 1971. Around 8.6 million 351W engines were manufactured between 1969 and 1996 at the Windsor Engine Plant Number One. During the 1990s, motor enthusiasts were modifying 351 Cleveland 2V cylinder heads (by rerouting the coolant exit from the block surfaces to the intake manifold surfaces) for use in the 351W, resulting in the Clevor (combining Cleveland and Windsor). This modification required the use of custom pistons by reason of differing combustion chamber terrain (canted valves vs. straight valves) and intake manifolds. This combination yielded the horsepower potential of the 351C with the ruggedness of the 351W small block and was possible because more 351C 2V cylinder heads were manufactured than the corresponding engine blocks (the 351M and 400 used the same head as the 351C 2V). The 5.8 L, 351W, was changed during the '90s from speed density to MAF; performance gains were directly affected. Before 1994, the 5.8 L was equipped with speed density. This programmed coding was placed into the vehicle's computer to tell the motor how much air it should be getting, therefore supplying an appropriate amount of fuel. However, if modifications are made to increase air flow, the computer does not provide more fuel until the oxygen sensors register a lean burn and only then can the computer compensate fuel trim. After 1994, the engine was changed to mass air flow (MAF). This allowed the computer to directly read how much air the engine was receiving through the help of a sensor in the air intake as long as that exact sensor was used (MAF sensors cannot be upgraded for increased flow without using an aftermarket chip or ECU). The rest of the intake system can be modified in any number of ways, but generally the MAF sensor remains stock). Because the computer reads this, it is able to increase the amount of fuel the engine gets when the air flow is increased, thus increasing performance. Applications: *1968–1974

In the early 1990s, a version and a high-output version that used GT-40 heads and the Holley 4160 marine carburetor was rated at . A few 351 GT-40/HO engines were marinized equipped with throttle-body fuel injection (TBI) and were rated at . The marine industry's relationship with the 351W platform ended when Ford was unable or unwilling to compete with GM's production of TBI- and MPI-equipped engines in mass quantity.
