Ford combined attributes that had worked well in previous incarnations of the FE: a 3.98 in stroke and a 4.13 in bore, creating an easier-to-make engine with nearly the same displacement. The 428 engine used a cast nodular iron crankshaft and was externally balanced. Standard 428 in³ FE engines were fitted to Galaxies (badged simply as ‘7 Litre’) and Thunderbirds in the 1966 and 1967 model years.
