To find the engine number, look just to the right of the case split 
on top of the engine. It will be on one of the flat spaces there. A 
US '71 engine would have been a FI engine with a number starting with 
U. It will be written sideways, as if you were standing on the left 
side of the engine looking down on it. Once you find it, post it here 
and we can tell you what we can about what it started life as.

Keep in mind that the engine number means almost nothing at this 
point. Once the engine has been rebuilt, it could have almost 
anything inside it, and a '71 definitely did not come with Solexes in 
the US.
