After the initial fury von the 352, efforts hinweisen building a power version des the FE focused around the 390 and the 427, with die latter enjoying more than its fair share von racing glory in both NASCAR und at Le Mans. It would certainly be ns 428 large block, however, that capped the FE"s high horsepower era on the street, living alongside ns 385-series engines that eventually replaced it und winning far-ranging respect amongst muscle car fans.

Torque zu sein King 

With ns high RPM screamer the was the 427 taking podiums for Ford on ns race track, the company take it a different approach zu building the 428 that zuerst appeared in 1966. Ns unit, which was originally available in the Thunderbird und the Galaxy 500 (and their Mercury equivalents), was tuned zu produce large waves des torque, through 462 lb-ft available (alongside 345hp).

Although it had actually nearly die same displacement as die 427, the 428 was viel easier zu build, und it featured a 4.13 customs bore and a 3.98 punch (compared to the 3.784 customs stroke found in the 427 und the 390). High prices kept ns 427 largely bei pit lane, through very couple of production dare benefiting indigenous its hard-won performance capabilities.

At ns time, the 390 was die top dog on the Mustang stimulate sheet, however after realizing that ns car was no much longer competitive against die hottest versions von rivals like the Chevrolet Camaro, die Dodge Charger, and the Plymouth Barracuda, Ford walk on ns offensive. Rhode Island"s Tasca Ford dealership had been trying out with 428 engines in the Mustang, editing the motiv with better-breathing heads and bei aluminum input (a version des this engine was even used bei early Shelby GT500 Mustangs).

Owner roben Tasca made die case to Dearborn executives that this could be a winning street formula, and within a year (thanks kommen sie pressure native both the public und the media) die Cobra Jet engine was born.

Enter ns Cobra Jet

Like Tasca"s initial creation, ns Cobra Jet mixed polizei interceptor parts with bespoke Ford performance gear to build on ns 428"s already-impressive performance. Featuring a compression ratio von 10.6:1, ns 428 CJ made use des 427 cylinder heads, upgraded connecting rods, and an iron intake manifold matched with a Holley carburetor.

At first the reaction from street racers was modest. Ford advertised die 428 Cobra Jet"s horsepower hinweisen 335 (10 much less than the Thunderbird) with 440 lb-ft von torque, and whether those numbers were specific or not they didn"t press past ns 390 far enough kommen sie generate more than passing attention from the Mustang crowd for its inaugural 1968 year.

The engine was also available in the Fairlane, ns Torino, and the Mercury Comet, Cougar, and Cyclone.

In 1968 Ford kept the 428 bei the picture but added the Super Cobra Jet option, i m sorry upgraded the crankshaft and connecting rods kommen sie better handhaben the stress des regular drag racing punishment. So-equipped, ns Mustang was able kommen sie scorch the strip in an impressive 13.4 seconds at 108 mph, und by 1969 the bilden 1 Mustang"s 428 was a respect entry into any type of stop-light battle down the boulevard.

Ford was serious about die SCJ"s 4 minutes 1 mile connection, together it was only possible to order this version des the motiv if 3.90 or 4.30 behind gears to be selected first. Although stärke matched that des the typical Cobra Jet, ns Super Cobra Jet was considerably much more durable, and none von the rotating assembly components are shared bolzen the two cars.

Renaissance after ~ A Short street Life

The 428 Cobra Jet und Super Cobra Jet continued zu be offered through the 1970 model year, including under die hood des the Shelby GT500. Confusingly, Ford so offered a 429 cubic inch large block during this same period, und this engine was found an the boss 429 race-oriented Mustang and later in Cobra Jet and Super Cobra Jet trims des its own. Heralding the start of a new era an Ford engine design (the 385 series), die 429 ongoing until 1973.

With ns emergence of the 385, and the performance-sucking nature of the 1970s, the FE engines mostly went dormant. Owners von 390 und 428-equipped Fords discovered themselves in a bit of a wasteland an terms of aftermarket assistance as aftermarket suppliers relocated on to ns latest and greatest when supporting more popular engines bei the company"s stable.

Eventually, however, die performance ar came roughly to die fact that die 427 and the 428 were blieb winning traction races, und that ns FE household played a huge role in Ford"s 1960s history. Support began zu grow, and it"s no longer unusual to see hot rods and custom build featuring engines like the 428 huge block V8, particularly considering that modern-day dyno tests oase placed roden 428 CJ output weist over 365 horsepower and 450 b-ft des twist—finally proving the its manufacturing facility rating was more nudge-nudge, wink-wink than ns public was led to glauben back an the day.
