That is a D9TE Block 1979 castingg configuration. The D9 blocks were used until end of 460 production. D9TE 460 has an externally balanced rotating assembly all other 429 and 460's have internally balanced assembly. The externally balanced rotating assembly utilizes a crankshaft that has slightly smaller counterweights. This apparently was done to so that the cylinders of the D9TE block could be extended about .200" deeper towards the crankcase. The cylinders of the D9TE blocks are lengthened because this block was to double as a med duty truck block, and the med duty truck rotating assemblies consisted of a very deep skirt piston that benefitted from the newly extended cylinder walls for support.
Earlier crankshaftsfts will not fit in the D9TE block as the counter weights will not clear the bottom of the cylinders.
