Hi Colin,
Thanks for the reply. Now I understand. I guess that Austin didn't have any "in-house" data for assessing crank strength of such a small engine when you think of the size of all the preceding Austin designs. Calculating the strength and fatigue resistance of a complex shape such as a crankshaft would be difficult without the use of computers. So being able to crib from a proven design would save a lot of trial and error.
