The Ford 302 Engine is a V8 engine made by the Ford Motor Company.

302 History
The 302 engine was the brain child of the engineers at Ford in the mid 1960's.

As the 289 had served many years as the staple v8 engine for the early and mid 60's. The time had come for more power, increased longevity, and easy emission regulation that would be needed to enter the 1970s. As the last of the 289's ran down the assembly line in 1968, Ford was faced with a dilemma. They were fast running out of 289 blocks. There was an ample supply of internal and upper end parts, but the blocks for the 289 were becoming scarce. Their solution was to take the internals of the 289 and put them into the newly found 302 blocks. This was no problem for the versatile 302 blocks. The 289 has a bore and stroke of 4.00 and 2.87 while the 302 holds a 4.00" and 3.00", making the internals a perfect match to salvage the last of the 289 parts. In 1968 the last of the 289's were retro fitted into the newly cast 302 blocks and the year went on as planned.

In 1968 was the 302's was released in two flavors: the regular two barrel carbuated version and the high compression 4 barrel carburated version. Another attribute that make 68 models special are that they have adjustable rocker arms. This was a one year only option. From 1969-71 the 302 was virtually unchanged but was no longer available with a 4 barrel carburator or adjustable rocker arms. 1972 was a dramatic year for Ford and the auto industry. The effects of CAFE's new emission and safety laws had finally caught up with Ford. Federally mandated 5 MPH impact bumpers were now required for all cars and vital compression points were dropped to fit new emission standards.From 1973-1981 the 302 remained diminished and anaemic, horsepower ratings hovered around the 140 mark and varied slightly depending on the application. In late 1977, the rockers were changes from rail style to a more efficient sled fulcrum.

As Ford entered the 1980s enough was enough. In 1982, "the Boss was Back". With a fresh campaign the time tested 302 moniker was changed to the 5.0 liter. The "Five-Oh" gave new life to the brand and new improvements brought a new wave of performance and efficiency. These performance ads were only for Mustangs and Capri's however, other Ford family vehicles kept with the standard two barrel carbutators and iron exhaust manifolds. This kept true till 1986. In the mean time the 1982 5.0L was featured with an aluminum two barrel intake, double roller timing chain, high lift cam and larger exhaust manifolds. This was just a peak at what was instore for 83 and 84. 1983 and 84 Mustangs gained an aluminum 4 barrel intake, stainless steel tubular exhaust manifolds and a Holly 600 carburator. While Mustangs received performance improvements, passenger cars were equipped with new electronics. Throttle body induction was added in 1980 to the Lincoln line up and was the first efficent attempt at Electronic Fuel Injection made by ford. In 1985, Mustangs and Capris received forged pistons, the 351 HO camshaft and roller lifters, these would be a performance addition only until the early 90s when all vehicles equipped 5.0L's all received roller lifters, however forged pistons would be switched to hypereutectic pistons in late 1992. For 1986 horsepower dropped slightly with the introduction of Sequential Mulitport Electronic Fuel Injection. This earlier form of EFI was controlled through Speed Density, while effective as it was, making modifications to the engine was difficult due to the pre-exhisting tuning and vaccume requirements. This was changed in late 1988 when Ford switched to Mass Air Flow. In the mean time the 5.0L heads were reworked and tuning improvements were made. The 1990s were around the corner and steps away from the 5.0L were being made. In 1991 the new 4.6 soch modular engine was introduced and the 5.0L began to be phased out. Overall horsepower for the 5.0L between 1985 and 1993 fluctuated around the 225 horse mark.

The last hoorah for the 5.0L was in 1993 with the introduction of the 1993 Cobra. This power house fetured GT40 heads, adjustable 1.7 Crane rocker arms and a special highflow intake to make maximum power. Although rated at only 235 horsepower, actual power numbers were reported to be in the 260's. With the redesign of the Mustang to the SN95 body style, the 5.0L was set in it's ways and was set on the back burner. For the 1994 and 1995 Mustangs, 5.0L horsepower was dropped to 215 because of the poor factory tuning of the ECU and the added weight of the vehicle. However the Cobra still carried over and boasted 240 horsepower. By this time full size vehicles had started switching over to the new 4.6. Trucks and SUV's were also preparing for the major switch. The newly redesigned Explorer's were still in the 5.0L game. In 1996 they received the time tested engine and were equipped with lower compression GT40 heads and intake. Although these didnt have the power numbers of the Cobras, their efficiency and durability made up for the difference. In late,1997 the 5.0L heads were reworked one last time and were given the moniker of GT40P. These changes involved moving the angle of the spark plug more towards the middle and raising the compression. The Explorer's were able to keep these power house 5.0L's until the engine was retired in late 2001.
