Hey Olev,
I have done that before!!
Almost as radical this time; a friend dropped off a worn-out bottom end from a 1954 A7SS on Sunday (A7SS 284; an early one), that he had bought on my behalf (without my knowledge!), so I guess I better build a bike around it!
All it takes is time, and about $8,000!
Ironically, a few years ago I gave away a complete A7SS engine.
Like every married man, I welcome challenges!
Muskrat, thanks - I hope you can help me; I didn't mention the head I will need!
Richard
