Aussie Hemi 6's

The ones used in the luxury Valiant VIP models. Those got put in front of Torqueflite automatics; the ones in lesser cars got the grossly inferior BorgWarner BW-35 automatic which was crude, rough, noisy, and less efficient but was built in Australia -- a big advantage given Australia's local-content laws of the time. There are different versions of the 245 and 265 engines depending on what transmission they went in front of.

thx dan!
