I know it can be done, because it has been done.but I just can't seem
to find anyone on the internet who has done it.



Any ideas.direction?



I was thinking cast cases, with more common/modern/avaiable internals.



Thoughts...cheers....jeers?

Check out the castinghobby group at yahoo.com for starters . Lotsa good
info there for your cases . As far as internals , you might consider
modified Harley crank parts - or homemade parts of similar design .
Shortened crankpin , run modified Sportster cams . How ya gonna lube this
thing ? I presume you want overhead valves ? Gonna be some interesting core
work on that head !
