Chevrolets were about the only car to retain iron pistons post 1930.
Cycles of heat on the stuck piston may help to free. If you have nothing else can be held over a candle! Clean bore with very fine paper. The conrod and white metal are precious so do not damage. The rings are sure to be stuck after piston is pursuaded out. Standing a household iron on the crown can be used to heat and may free. If wear is moderate and piston skirts not collapsed, pistons and bores may be reusable.
The crankpins are drilled to provide communication from the oil receiving troughs in webs to the crankpins. If you have not noticed the oil jets in crankcase, take care not to damage.
