The 428 SCJ engine required an engine oil cooler that was mounted in front of the radiator on the driver's side of the radiator core support. This required moving the driver's side horn to the passenger side of the radiator core support to make room for the oil cooler. The relocated horns were usually secured to the core support using a reinforcement plate that was mounted on the back side of the core support.
Ford crankshaft damper spacers are identified by basic part number 6359. This part fits over the front end of the crankshaft snout and fills the space between the harmonic balancer and the timing cover. The 428 Cobra Jet and Super Cobra Jet spacers are made of steel and were typically unpainted when installed.
Ford carburetor spacers are identified by basic part number 9A589. The spacers used on the 428 CJ and SCJ engine are made of a black plastic material that is similar to bakelite. The spacers are not marked with an engineering number.
Ford engine oil level indicators (sometimes referred to as a dip stick or dipstick) are identified by basic part number 6750. Ford used two different service part numbers for the indicators used with the 428 CJ and SCJ engine.
Ford connecting rods are identified by basic part number 6200. Made of forged steel, the rods used in the 428 Cobra Jet and Super Cobra Jet engines measure 6.488 inches in length from center to center. Part of the engine's reciprocating assembly, connecting rods connect the pistons to the crankshaft.
Several different air cleaner assemblies were used on Cobra Jet Mustangs during the 1968, 1969, and 1970 model years. Instead of trying to identify them all on one page, we're going to separate them into several broad categories based on air cleaner type and model year. Use the links below to jump to the ID pages.
Ford power steering pumps are identified by basic part number 3A674. The pump used on Cobra Jet Mustangs is known as a "Ford-Thompson" power steering pump because it was manufactured by two companies, Ford Motor Company and TRW (which was known as Thompson Ramo Wooldridge prior to 1965). It's a belt-driven slipper-type pump that includes an integral steel fluid reservoir. The reservoir is attached to the rear of the pump and the pump body is inside the reservoir.
Ford identified the steel engine oil cooler used on 428 SCJ engines using basic part number 6A642. The 1975 Master Parts Catalog identifies the pump using service part number C9OZ-6A642-A. The engineering number is C9OE-6A642-B. The same cooler was used on the 1969 and 1970 Boss 429, 1970 429 SCJ, and 1970 Boss 302.
Ford alternators are identified by engineering part number 10300. 1968, 1969, and 1970 Mustangs were originally equipped with either a 38A (amp), 42A, or 55A Autolite alternator depending on the engine and installed options. Certain power-hungry options, like air conditioning, typically included a higher output alternator as part of the package.
Ford water pumps are identified using basic part number 8501. Like most water pumps of the time, the pump used on 428 CJ and SCJ engines is driven using a belt and pulley arrangement. The pulley bolts to a flange on the front of the pump. The belt routes around the crankshaft pulley, turning the pump with each rotation of the crank.
