Big 4 engine info

Forums

Does anyone know of a reliable info/data source for the post-war Big 4 engines?  Having learnt enough on the 16H's (current bike is now running superbly - see recent carb conversation) I decided to expand my SV experience to the big brother.  

So far I have sourced an excellent barrel and new piston via NOC, have an alloy head already, crankcases on order and am hoping to create a c.1948 spec engine one day.  Cranks seem very hard to find.  

But I'm really looking for more details on interchangeability of 16H cams, followers, oil pumps etc which I suspect would have been common to both engine build lines but I'm not sure.  

Roy Bacon's book doesn't have much on this model.
