To clarify:

429 CJ + Drag Pack = SCJ

Despite what some sources may suggest, a J-code doesn't make a SCJ, and the Drag Pack was available on non-ram air CJs (The C-code).

Ram air was available from the 351-2 on up, and they all were Shakers. No ram air without a Shaker.

The slope nose car is the stillborn King Cobra, which was built to beat the Daytona and Superbird. It never made production. I also don't know what's between the fenderwells, but it could be a "plain" CJ for all I know.

The Drag Pack added some reinforced/heavy duty parts to the CJ, plus 3.91 or 4.30 gears. You can't tell a SCJ from the VIN, but you can use deductive reasoning and figure it out from the axle code on the data plate. However, some 4.30 cars have been found on lesser engines, but those were anomalies and it's still good to use it as a rule of thumb.
