428 Engines

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.

428 Cobra Jet

The 428 Cobra Jet, launched in April 1968, was a version of the 428 FE engine built for performance rather than cruising smoothness. The 428 Cobra Jet could be made on a regular production line, not requiring the exacting tolerances required by the 427. The 428 Cobra Jet has greater low-end torque than the 427, thanks to its longer stroke. The Cobra Jet used a strengthened version of the 428 block with an extra main bearing webbing and thicker main caps than the standard block. The engine was underratedat 335 hp (250 kW) at 5200 rpm. The 428 Cobra Jet actually produced 400 to 410 hp (299-306 kW)

428 Super Cobra Jet

The 428 Super Cobra Jet used the same top end as the 428 Cobra Jet but the crankshaft, connecting rods, and pistons are different. Cast high-performance pistons and a different crankshaft were used, as well as heavy 427 “Le Mans” connecting rods with capscrews instead of bolts for greater durability. An engine oil cooler was standard equipment with the Drag Pack and 3.9 or 4.3 rear end gear ratios This engine was also underrated at 335 horsepower (250 kW). There is no horsepower or torque difference between the 428 Cobra Jet and 428 Super Cobra Jet.
