caption_attribution_description: 1968 Mercury Cougar convertible(not factory)302 4V Windsor V8. Note that the "4V" refers to the car's 4-barrel carburetion (twin 2-barrels); it does not have a 4-valve head. "4V" Stands for 4-Venturi
context_page_description: The Ford Small Block is a series of automobile V8 engines built by the Ford Motor Company beginning in July 1961. The engine was discontinued in new trucks after 1996, and new SUVs after 2001, but remains available for purchase from Ford Racing and Performance Parts as a crate engine. Although sometimes called the "Windsor" family by enthusiasts, Ford itself never named the engine family; the designation was only adopted to distinguish the 351 cu in version from the Cleveland 335-family engine that had the same displacement, but a significantly different configuration. The designations of 'Windsor' and 'Cleveland' were derived from the locations of manufacture: Windsor, Ontario and Cleveland, Ohio.
  The engine was designed as a successor to the Ford Y-block engine. Production began in 1961 for installation in the 1962 model year Ford Fairlane and Mercury Meteor. Originally produced with a displacement of 221 cu in, it eventually increased to a maximum displacement of 351 cu in, but was most commonly sold with a displacement of 302 cu in, with engines of that displacement offered from 1968 until 2000.
context_section_description: By 1967, the Ford GT40 MKII and GT40 MKIV had dominated the Le Mans 24-Hour Race 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 3 in (76.2 mm), giving a total displacement of 4,942 cc (4.9 L; 301.6 cu in). 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 1.773 in (45.0 mm) (intake) and 1.442 in (36.6 mm) (exhaust), and was rated (SAE gross) at 220 hp (164 kW) at 4,600 rpm and 300 lb⋅ft (407 N⋅m) at 2,600 rpm. Optional was a four-barrel version rated at 230 hp (172 kW) 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 dampener 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.
  Emission regulations caused a progressive reduction in compression ratio for the 302 two-barrel, to 9.0:1 in 1972, reducing SAE gross horsepower to 210 hp (157 kW). In that year, U.S. automakers began to quote horsepower in SAE net ratings; the 302 two-barrel carried a net rating of 140 hp (104 kW). By 1975, its power dropped as low as 122 hp (91 kW). Until fuel injection began to appear in the 1980s, net power ratings did not rise above 210 hp (157 kW).
  From the 1978 car model year, the 302 became more commonly known as the 5.0 Liter, although its metric displacement is 4,942 cc (4.9 L; 301.6 cu in). Ford may have used the "5.0" moniker to distinguish the 302 from their 300 cu in (4.9 L) inline six, which was known as the 4.9. Despite its advertised displacement, Car and Driver referred to the 302 as a 4.9-liter engine, though in common usage it is typically called a "5-Oh, 5-Point-Oh, 5 Liter, or 302".
  Throttle-body fuel injection became available on the 1980 Lincoln Continental, and became standard on all non-H.O. 5.0 engines for 1983. For the 1986 model year, Ford replaced the throttle-body system with sequential multi-port fuel injection, identifiable by the large intake with an "EFI 5.0" badge on top.
