What Year Did Ford Start Using 302 Engine Again

Hither's How Ford'south 302 Modest Cake V8 Evolved Into The 5.0 And Defined High Performance For 30 Years

The Ford small block V8 engine'due south greatest champion was the 302. Dubbed the v.0 subsequently in life as the industry moved from cubic inches to liters in describing displacement, information technology was the workhorse of the automaker'southward line-up, pulling duty in everything from sports cars to vans to pickup trucks.

The 302 arrived on the scene at the terminate of the 1960s as a high performance option for the Mustang, merely it not just had its roots deeper in Ford's past, it would have a future touch that extended well beyond the pony car, as well.

All-New Compages

The Windsor family of Ford V8s debuted in 1961 as a replacement for the Y-cake series. Over the side by side few years the engine's displacement was aggressively increased, moving from 221 to 260 to 289 cubic inches, with the latter gaining a foothold in a long list of intermediate and even full-size Ford cars and trucks (including the Mustang, the Torino, the Fairmount, the Galaxie, and the Falcon).

The 302 cubic inch version of the Windsor pocket-sized block arrived in 1968, stroking out the 289 to 3.00 inches simply retaining the same pistons (by style of shortened connecting rods). This provided for expert parts compatibility between the 289 and the 302, which featured up to 230 horsepower and 310 lb-ft of torque (with a iv-barrel carburetor installed). The standard motor was given a compression ratio of 9.five:1, and it came with hydraulic lifters, but the Shelby GT350 added a unique high-rise intake every bit well as larger valves and a college pinch ratio to boost output to 315 hp and 333 lb-ft of torque.

The following year Ford likewise offered the Boss 302, which share only its displacement with the Windsor motor (as it included 4-bolt mains instead of 2-bolt, its own casting, and completely different cylinder heads). With solid lifters and many parts borrowed from the G-Code or 'Howdy-Po' version of its 289 cubic inch predecessor, the Boss produced 290 hp and 290 lb-ft of torque and was the centerpiece of Ford's Trans-Am racing program for both the Mustang and the Mercury Cougar. The engine lasted until the 1970 model year.

The Small Block That Stayed

Ford continued to enlarge the Windsor, adding an inch of deck height and increasing the stroke to iii.5 inches for a 351 cubic inch version of the engine, but unlike past modest blocks the 302 didn't exit the scene after its bigger sibling arrived. Instead, it stuck around every bit the base eight-cylinder pick in much the same range of vehicles it had debuted in, condign i of the most versatile options in the Ford portfolio.

Of form, the 302 pocket-sized block wasn't immune to the same pressures that were facing every other engine during the dark years alee. In 1971 the 4-barrel option was no longer offered with the motor, and by 1972 compression has been reduced to nine.0:1, dropping horsepower to 210. The net horsepower ratings and further EPA smog choking had the venerable engine down to a measly 122 hp at the mid-bespeak of the '70s, and it hovered betwixt there and 140 horses the next few years before briefly disappearing from the order sheet for 1980-81 in favor of a poorly-received, smaller bore version of the same small block.

Past that fourth dimension Ford decided it was time to modernize the Windsor motor, and what better starting signal than the old stand-past, the 302, which had been renamed the 'v.0' in 1978 as part of America'south ill-fated push towards adopting the metric arrangement. The first signs that the 302/5.0 might have new life in it came in 1982 when 'Loftier Output' of 'H.O.' version of the engine arrived under the hood of the Ford Mustang and its Mercury Capri clone.

The motor borrowed its camshaft from the marine version of the 351 (irresolute its firing order versus the previous 302 incarnation), merely compression was withal depression, checking in at 8.3:1, and the heads from the previous year's four.ii-liter V8 were even so in service. Power began to climb for the HO, rising from 157 hp and 240 lb-ft of torque in its start year, jumping to 175 hp in 1983 cheers to the inclusion of a four-barrel carburetor matched with a much-improved dual-airplane intake.

Fuel Injection Changes The Game

Archaic throttle-body fuel injection striking the scene in 1984 as an choice, knocking power back to 165 ponies, but a serial of dramatic improvements to the 5.0 H.O. in 1985  (including hydraulic roller lifters, a new camshaft, improved exhaust, and a fresh set up of heads) made the carbureted version of the engine (notwithstanding on the options list) much more potent.

Horsepower jumped to 210 and torque climbed to 265 lb-ft, and while the motility to EFI-only the following yr knocked x horses from the spec sail there was no dubiety that the 5.0 had finally arrived as a truthful '80s operation motor.

From that point on, the split between 5.0 H.O. (found in the Mustang/Capri, the Ford Thunderbird and LTD Threescore, and the Lincoln Mark VII) and standard versions of the 302 (used primarily in trucks, larger passenger cars, and vans) became more definite.

Aside from firing guild, the H.O. too embraced SEFI multiport fuel injection for the regular 302 and gained a revised head blueprint in 1987 that helped heave output to 225 hp and 285 lb-ft of torque. A couple of years later mass airflow fuel injection was introduced, which would be the last major modify for the H.O. until the inclusion of hypereutectic pistons for 1993.

A Cobra R version of the motor pumped out 240 horses when it was introduced in 1993, thanks to GT-40 heads, a larger throttle body, and a unique aluminum intake manifold.

A Long-Lasting Legacy

By the end of 1995, the Windsor V8 was no longer offered in the Mustang, having been replaced by the 4.6L modular V8 that served equally Ford's performance backbone for the next 15 years.

The engine lived on until 2001 nether the hood of the Ford Explorer SUV (and its Mercury Mountaineer clone), making these trucks the terminal bearers of a 30 year Windsor legacy.

Today, both the archetype 302 and the modern five.0 H.O. stand up as some of the all-time-supported V8 engines that the aftermarket has ever seen. Thanks to their sheer ubiquity, there are thousands of shops and hundreds of thousands of loftier performance parts available for the entire Windsor family unit of motors.
