Maybe there has been some prior talk in here about this project that I missed ...
But, Why a Cleveland crank in a Windsor block?
What is the advantage? I've heard of 400 cranks in Windsor blocks, but you a gaining stroke with that set-up. Aren't you just trading a 3.5" stroke for a 3.5" stroke and in the process creating some "engineering" headaches?
As I understand it the Windsor rotating assembly is lighter than the Cleveland so one might expect quicker response form the Windsor.
Talk to me ... I think there must be something here for me to learn
