surface rust on crank. Still usable?
I have my crank and rods still sitting in the old 350 block I have until it's time to assemble my block that was machined. There is some surface rust on the crank but it's not on any of the journals because the rods are still attached and crank is torqued down. There is a lot of rust by the rear where the flywheel bolts too also. Can this be cleaned off with a wire brush and some chemicals or should the crank be hot tanked? wouldn't that ruin the finish on the journals though?

If it's not on the journals there's nothing to worry about.

None of the rest of it matters in the slightest. A bit of wire brush or Scotchbrite and all will be well. Maybe smear a light film of grease on it to keep it from coming back.
