G'day Mowerfreak,
Holden's early V8 models, from the late 1960s [i.e. HK on], were all Small Block Chev powered. The engines that were fitted here were the 307, 327 and 350ci sizes.
Even after the Aussie 308 came out, the 350 Chev was still available in Monaros, in a high-performance guise - 4-barrel carby, big port heads etc. Optional in Statesmans for a while too, IIRC.
