Intake Manifold

The most common intake manifold used for both 428 Cobra Jet and Super Cobra Jet engines from 1968 through 1970 is easily identified. It's a cast iron, 4v dual plane design that carries engineering number C8OE-9425-C. According to Chris Teeling, some early 1968 CJs came equipped with an intake carrying engineering number C80E-9425-A. Chris says "The -A more resembles a 428 PI intake casting. The size of the engineering numbers are much larger and there is "XE" number on the #1 runner which is partially ground off" (more on the -A intake below).

Engine Lift Hooks

All 428 Cobra Jet and Super Cobra Jet engines were originally equipped with a pair of stamped steel lift hooks that were used to lift the engine during the installation process. The most common driver's side hook is roughly figure-eight shaped, has two lifting holes and is stamped with an engineering number and a Ford logo. The passenger side hook is triangular, carries no engineering number or markings, and has a single lifting hole. Both hooks were painted engine color, "Ford Dark Corporate Blue" (note that they were painted off the engine).

Hood Scoop (1968)

Ford identified the functional fiberglass hood scoop used on 1968 Mustangs using basic part number 16C630. The 1975 Master Parts Catalog identifies the 1968 hood scoop using service part number C8ZZ-16C630-A. Based on parts found "in the wild" it appears that at least three different hood scoops were used on 1968 Mustangs over the course of model year production. The last version was itself replaced by Ford with the 1969-1970 version (identified by service part number C9ZZ-16C630-C) as of March 1974.

Cylinder Heads

The cast iron cylinder heads used for both 428 Cobra Jet and Super Cobra Jet engines from 1968 through 1970 (part number C8OZ-6049-K) are easily identified by casting number and physical appearance. The casting number, C8OE-6090-N, can be found in the recessed area between the middle two spark plugs as shown in the picture below. If the casting number is questionable, check the number of bolt holes on the exhaust manifold face for additional identification assistance (428 CJ heads should have sixteen bolt holes).

Electronic Engine Governor (Rev Limiter)

Electronic engine governors, also known as RPM or rev limiters, were used on 1970 428 Cobra Jet engines when the car was equipped with a manual transmission (they were also used on Boss engines, but that's not what we're here for). The 1975 Ford Master Parts catalog only mentions use with a standard transmission for 1970 428 CJ and SCJ, and I haven't been able to confirm factory installation on a car equipped with an automatic transmission.

Fuel Pump

Ford fuel pumps are identified by basic part number 9350. 428 CJs and SCJs were originally equipped with a mechanical fuel pump made by Carter with a service part number of C7AZ-9350-A. The pump is driven by an oblong "eccentric" that mounts to the front of the cam. As the eccentric rotates, it pushes the lever on the fuel pump up and down, which in turn moves an internal diaphragm up and down, which creates a vacuum that draws fuel from the fuel tank into the pump and up to the carburetor.

Flywheel (Manual Transmission)

Ford manual transmission flywheels are identified with basic part number 6375. All 428 Cobra Jet and Super Cobra Jet engines were originally externally balanced by Ford. That is, external components like the harmonic balancer and flywheel play an integral role in balancing the engine's reciprocating assembly. Original flywheels are made of cast iron for longevity, though racing replacements are available in aluminum to eliminate some weight.

Flywheel (Automatic Transmission)

Ford automatic transmission flywheels are identified with basic part number 6375. All 428 Cobra Jet and Super Cobra Jet engines were originally externally balanced by Ford. That is, external components like the harmonic balancer and flywheel play an integral role in balancing the engine's reciprocating assembly. The CJ and SCJ flywheel balance weights are not identical: the SCJ weight is shorter, and the 1975 Ford master parts catalog says that the SCJ flywheel's diameter (15 1/2") is about 1/32" less than the CJ flywheel's diameter (15 17/32").

Air Conditioner Valve and Heater Motor Shield

Due to the size of FE-series engines and the close confines of the Mustang engine compartment, Ford found it necessary to mount a shield (identified by basic part number 19C842) to protect the heater blower motor (for cars without air conditioning) or the air conditioning expansion valve (for cars with air conditioning) during engine and transmission installation on Mustangs equipped with a 390, 428 CJ, or 428 SCJ engine. This shield is made from stamped steel and is typically painted the same semi-gloss black as the firewall itself.
