For 1966 Ford combined attributes that had worked well in previous incarnations of the FE – a {{cvt|4.13|in|mm|2}} bore and a {{cvt|3.98|in|mm|2}} [[Stroke (engine)|stroke]] – to create an easier-to-make{{how|reason=The 390 and 427 had identical 4.2328 bores (on identical 4.63 bore spacing), and Ford made countless millions of the “commodity“ 390 V8 (a completely conventional engine used in countless applications).  How was the 428 cheaper to make, and why was it needed to supplant the 427|date=May 2024}} {{cvt|428|cuin|L|1}} engine. It used a cast nodular iron [[crankshaft]] and external balancer.

428 FE engines were fitted to [[Ford Galaxie|Galaxies]]
(badged simply as '7 Litre') and [[Ford Thunderbird|Thunderbirds]] in the 1966 and 1967 model years. It was also found in Mustangs, Mercury Cougars, some AC (Shelby) Cobras and various other Fords from 1968.  This engine was also available as standard equipment in 1966 and 1967 in the [[Mercury S-55]].<ref>{{cite book

=====428 Cobra Jet=====

The ''428 Cobra Jet'' was a performance version of the 428 FE. Launched in April 1968, it was built on a regular production line using a variety of cylinder heads<ref>{{cite web |url=https://www.428cobrajet.org/id-heads |title=Cylinder Heads {{!}} Mustang 428 Cobra Jet Registry}}</ref> combined with a 735 CFM Holley four-barrel carburetor. The Cobra Jet used heavier connecting rods with a 13/32 rod bolt and a nodular iron crankshaft casting #1UB. A Holman and Moody specially prepared "stripper", which carried no sound deadener, undercoating, or any optional factory equipment, was used as the introductory press car in 1968.<ref>{{cite web |url=http://www.mustangandfords.com/featured-vehicles/mdmp-0707-fastest-mustang-tests |title=Fastest Classic Mustang Tests - Who Would Be King?|date=July 2007 }}</ref>

The 428 Cobra-Jet had a compression ratio of 10.8:1 and was rated {{cvt|335|bhp|kW|0}} at 5200&nbsp;rpm and {{cvt|440|lbft|Nm|0}} at 3400&nbsp;rpm. Historical road test data on actual production 428 CJ cars suggest peak output in the neighborhood of 275 SAE Net ("as installed") HP, using published trap speed and "as tested" weights, and Hale's trap speed formula.<ref>{{cite web |url=https://www.motortrend.com/how-to/testing-4-2-8how-much-horsepower-ford-428-cobra-jet-really-make/ |title=Testing 4-2-8…How Much Horsepower Does the Ford 428 Cobra Jet Really Make?|date=21 November 2016 }}</ref> Period road tests revealed quarter mile performance in the low 14-second to very high 13-second range, with trap speeds around {{cvt|101|to|103|mph}}:<ref>{{cite magazine |url=http://wildaboutcarsonline.com/members/AardvarkPublisherAttachments/9990494729848/1969-02_SS_1969_Mustang_Mach_1_428_CJ_Test_1-4.pdf |title=Mach I Mustang CJ428 |author=McGonegal, Roland |date=February 1969 |magazine=Super Stock |pages=21–23;72}}</ref>

The 428 Cobra Jet engine (modified to the NHRA [[Stock (drag racing class)|Stock]] and [[SuperStock (drag racing class)|Super Stock]] technical specifications) made its drag racing debut at [[1968 NHRA Winternationals]], held from February 2–4, 1968, at the [[Auto Club Raceway at Pomona|Auto Club Raceway]] at [[Los Angeles County Fairgrounds]], in [[Pomona, California]]. Ford Motor Company sponsored five drivers ([[Gas Ronda]], [[Jerry Harvey (drag racer)|Jerry Harvey]], [[Hubert Platt]], [[Don Nicholson|"Dyno Don" Nicholson]], Kenneth McLellan, and [[Al Joniec]]) to race six 428 CJ-equipped Mustangs. They raced in classes C Stock Automatic (C/SA, {{cvt|9|to|9.49|lb/hp|kg/kW}}), based on advertised horsepower) and Super Stock E (SS/E or SS/EA, manual or automatic transmission, respectively, at {{cvt|8.70|to|9.47|lb/hp|kg/kW}}, based on factored horsepower). The engine lived up to expectations as four of the cars made it to their respective class finals. Al Joniec won both his class (defeating Hubert Platt in an all-CJ final) and the overall Super Stock Eliminator title (defeating Dave Wren who ‘red lighted’ in his faster 426 Race Hemi Plymouth).<ref>{{cite web|url=http://www.428cobrajet.org/pomona.html |title=428 CJ Mustangs at the 1968 NHRA Winternationals &#124; Mustang 428 Cobra Jet Registry |publisher=428cobrajet.org |access-date=2014-02-28}}</ref>

=====428 Super Cobra Jet=====
The ''428 Super Cobra Jet''  (also known as the 428SCJ) used the same top end, pistons, cylinder heads, camshaft, valve train, induction system, exhaust manifolds, and engine block as the 428 Cobra Jet.  However, the crankshaft and connecting rods were strengthened and associated balancing altered for drag racing. A nodular iron crankshaft casting #1UA was used as well as heavier 427 "Le Mans" connecting rods with capscrews instead of bolts for greater durability. The heavier connecting rods and the removal of the centre counterweight on the stock 428 Cobra Jet crankshaft (1UA), required an external weight on the snout of the crankshaft for balancing. A 428 Super Cobra Jet engine with oil cooler was standard equipment when the "Drag Pack" option (which came when selecting either a 3.91 or 4.30 rear end gear ratio) was ordered with cars manufactured from 13 November 1968.  In addition, while the CJ and SCJ engines used the same autothermic piston casting, the piston-to-bore clearance specification between the CJ and SCJ 428 engines is slightly different, with the SCJ engines gaining a slightly looser fit to permit higher operating temperature.<ref>{{cite web|url=http://www.428cobrajet.com/id-piston |title=Pistons &#124; Mustang 428 Cobra Jet Registry |publisher=428cobrajet.com |access-date=2014-02-28}}</ref> Horsepower measurements at a ''street'' rpm level remained the same.<ref>{{cite web|url=http://www.428cobrajet.com/cj-vs-scj |title=428 Cobra Jet vs. 428 Super Cobra Jet &#124; Mustang 428 Cobra Jet Registry |publisher=428cobrajet.com |access-date=2014-02-28}}</ref> The 428 Super Cobra Jet engine was never offered with factory air conditioning due to the location of its engine oil cooler.
