Automotive historians have extensively documented the differences between the violent and brutal Ford 427-cu.in. V-8 and the refined, velvet hammer Ford 428-cu.in. V-8. Both occupy pedestals in the Hallowed Hall of Great Ford Engines, but the short-stroke 427 tap-danced on the tachometer's redline while the long-stroke 428 delivered tugboat-type torque. The former lived for crushing the competition at the dragstrip and on NASCAR's tracks while the latter felt more at ease cruising the open highway.--
It was in that context, then, that Ford introduced the 428 on October 1, 1965, tucked snugly into the engine bay of the 1966 Galaxie 500 7-Litre, a sporty edition of the full-size Ford created specifically to showcase the new engine. Ford had, just a year earlier, redesigned its full-size cars' frames and suspensions to provide a much smoother and more stable ride, one that Ford alleged rivaled the Rolls-Royce in quietness.
While Ford still had the 427 on the full-size's option sheets, ordering one up precluded many creature comfort options. The 428, however, didn't--thus Ford's rationale for introducing it in such a refined mode of transportation.
All cigars and reading room slippers, the 7-Litre, however, was not. Bucket seats, a console, dual exhaust, disc brakes and the beefy C6 automatic transmission came standard, and a four-speed could replace the C6 at no charge.
Ford made the 7-Litre available in just the two sportiest full-size body styles--two-door hardtop, of which Ford built 8,705, and convertible, of which Ford built 2,368. (Ford made the 428 itself optional in all full-sizes and Thunderbirds.) The 7-Litre's divisional sibling, the Mercury S-55, also used the 428, but only 3,585 left showrooms.
The 7-Litre returned in 1967, as the 7-Litre Sports Package, an option on the XL and sans the badging that distinguished the 1966 7-Litres; according to Kevin Marti's numbers, Ford built just 855 XL two-door hardtops and a mere 213 XL convertibles with the 7-Litre Sports Package.
Even with that badging, however, Ford didn't make it simple to pick out a 7-Litre from the hundreds of thousands of other full-size hardtops and convertibles: The 428 resided on the option sheets of every full-size that year, and the subtle identifying characteristics of an actual 7-Litre tend to prove too subtle for casual scrutiny. But, armed with the right information, anybody can spot the details that separate a true 7-Litre from any ol' well-optioned full-size.

ENGINES
Even though it took a couple years for Ford to develop the Cobra Jet variant, the 428 as used by the 7-Litre still developed a respectable 345hp at 4,600 rpm and 462-lbs.ft. of torque at a rather low 2,800 rpm. Technically dubbed the 428 Thunderbird 7-Litre V-8, the 428 used a single 480cfm Ford four-barrel carburetor and 10.5:1 compression ratio, along with hydraulic lifters and the standard FE-series two-bolt-main engine block.
The cast-iron cylinder heads followed the typical FE-series design, with 2.04-inch intake valves, 1.57-inch exhaust valves, 1.93- by 1.34-inch intake ports and 1.84- by 1.28-inch exhaust ports. Bore and stroke measured 4.13 inches and 3.98 inches, respectively.
