Welding cast iron is tricky, especially for a crank that subject to
load, vibration, and temperature extremes. It can be done if the welder
knows what he's doing but how can you tell? A local guy here had a
Buick 300 iron crank welded up and then ground down so he wouldn't
need the seal adapter when installing it in an Olds 215 block. He races
the engine in a modified Lola chassis and has had no problems but the
welder was very good. Steel cranks are much easier to weld.
