The #1 main and consequently the #1 rod bearings are the furthest point 
from the oil pump... rod #2 gets oil from the main #2, so there should be 
no damage there _if the problem was the oil feed.

The rust on the top of the motor is something else, but it indicates to me 
that there was water INSIDE the sump or a lot of condensation in the valve 
cover area... was the motor stored in the upright position???

I agree with Vance - it'll cost more to fix the crank than to get another 
servicable used or new (my pref. is NOS) crank. They are def. available 
from various sources.

I'll also point out that if you run the motor starved for oil, the #1 
bearing will spin first. The damage to the cam probably came later, but 
verify that your oil filter is in play for this motor...

I'm thinking that there was some crud in the oil line that blocked oil 
flow from the #1 main to the #1 rod.
