There was one more engine configuration. The 429 Super Cobra Jet Drag Pack. For the additional cost—just $155, recall—you got four-bolt caps on the middle three main bearings, forged aluminum pistons on heavier-duty connecting rods, a solid-lifter camshaft with more aggressive profile (versus a hydraulic cam fitted into the lesser 429s), a genuine Holley 4150-series carburetor flowing 780 cfm (and a functioning Shaker scoop when the J-code Ram Air engine was specified) flowing 12 percent more air, an oil cooler mounted to the radiator support, header-style exhaust manifolds, and more.
