All FE blocks have the same bore spacing and main bearing diameters. So all crankshafts will fit in any FE block, however, the some rod and piston combinations will have clearance problems in the 352 & 332 blocks. 

Until 1965, all FE cranks were cast iron. The iron crankshaft did not create reliability problems. The motors were raced in all sorts of races with good results. Ford said they motors were good to 7000 RPM and upwards of 600 horsepower.
