A 428 is often characterized by the fact that it has just one spark plug on the plug, that it requires a stick or cane, and that it should be measured at 3 by measuring the stroke of the rod (see illustration).To demonstrate this, consider the numbers 9807′′ for a 3.9, 3904067′′ for a 3.8, and 4274′′ for a 4.0.Additionally, there is a 3 at the 780 level, which may be found with a 330, 352, or 360 pattern.

Given its smaller displacement volume, the 429’s stroke length of 3.59 millimeters was shorter than that of the 460’s stroke length of 3.85 millimeters, which meant it produced less power per camshaft spin. More power is produced by the longer stroke, which also makes it possible to make more and better high-performance modifications.
