Just wondering. I have one that I think is 0.010"/0.010", machined on the snout and on the butt for passenger car use. Stock 3.78" stroke. I thought these forgings were fairly valuable. Granted, you can buy the Chinese forged cranks for the same or less with a lot more stroke.
I bought one ready to go in a passenger car FE for $450 and was happy to get it. I bought another 391 crank that was unmodified for $200. Then I paid an American craftsman $1500 for a whole lot of machine work on it. I'm super happy with that.
Where are these old things worth these days?
thanks,
