I have one of these cars, but a Torino Cobra model. I can tell you a bit about what I know:
- There were two 429 CobraJet (CJ) motors in 1970, and this will be coded as the 5th digit of the VIN. The 'C' code will be for the 429 non-ram-air version, and the 'J' code will be for the 429 Ram-Air version (with desirable shaker scoop).
- The "Super" Cobra Jet (SCJ) is more confusing. This option upgraded a lot of features of the CJ motor, but Ford didn't change the engine code. The SCJ was really just an option on the C and J code motors. So you could have an SCJ motor with Ram Air (J) or without (C), meaning the VIN won't reflect this SCJ Option.
- The reason why this SCJ is an option is because Ford considered it an Axle Package Option, aka Drag Pack. One easy way to tell if you have a real SCJ is by looking at the Axle code on the door tag. The Drag Pack got you either the V (3.91:1) or W (4.30:1) rear axle. In combination with a C or a J code in the VIN then you know this car is actually a real SCJ if it has one of these two axle codes.
- In addition to one of these two rear axles the SCJ/DragPack option also added an oil cooler, solid lifters, a different cam, different intake, different carb, 4 bolt mains, 3/8 fuel line, etc. Really, this SCJ 'option' was an entirely different engine configuration, but I guess since it could be added to either the C or J code 429s they left it as an option. A bit confusing.
