Some years ago I also exchanged a number of emails with Jim Steck (in the US) and I mentioned this monoblock since Jim was in the process of making his own for the Bonneville TS. Jim felt there were inherent flaws in the Australian design and designed his as a combination of girdle and monoblock. Jim sent me the first photo after 12 hours of straight milling. The second is of the competed work of art.

I would be interested in what was seen as inherent flaws in the Australian design.Also I have noticed that the bottom of jims liners are all cut through on one plane(like the old GTAM Monobarrels) and not STEPPED as on the Australian design which allows more material around the main bearing which has to be stronger for the bottom end. The girdle at the top of jims monoblock is a good idea which was first done in the 1980,s in italy by the PEDRAZZANI BROTHER for their company NOVAMOTOR based in Novara building alfa F3 engines 105/116 engines and TSPARK.
