In 1983 the carbureted engine was replaced with throttle-body fuel injection. 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. Until fuel injection began to appear in the 1980s, net power ratings did not rise above 210 hp (157 kW).įrom 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).

By 1975, its power dropped as low as 122 hp (91 kW). automakers began to quote horsepower in SAE net ratings the 302 two-barrel carried a net rating of 140 hp (104 kW). 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.Įmission 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). Along with the move came most changes that stayed with it for the remainder of its life. In 1970, the manufacturing of the engine was moved from Windsor, Ontario to Cleveland, Ohio. This is where the 302 Windsor name comes from. The 302 was manufactured in Windsor from 1968 to 1978. Optional was a four-barrel version rated at 230 hp (172 kW) at 4,800 rpm. 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. The most common form of this engine used a two-barrel carburetor, initially with 9.5:1 compression. It replaced the 289 early in the 1968 model year. The connecting rods were shortened to allow the use of the same pistons as the 289. The Ford 302 V8 came about in 1968, after Ford stroked the 289 V8 3-inches giving it a total displacement of 4,942 cc (4.9 L 301.6 cu in). This page is here to help you better understand this engine, and serve as a guide to picking the 302 / 5.0 that’s right for you. Although Ford never offered the 302 / 5.0L in the Ford Ranger, plenty of them found their way in to them.
