The Chrysler slant six was made in three different sizes. 170, 198, 225 cubic inches. This is for the USA, and Canada. As far as I know the Australian slant six was only built as a 225 CID. Also as far as I know, all non automotive slant six engines were 225 Cid. The slant six was used in a lot of different applications, from farm equipment, to aircraft tugs, lift trucks, stationary pumps, and welders. Here is an odd ball
