73's were all forged in 440's; cast crank started in 1974, but forged still used in some applications.

I disagree and so does the factory, check TSB 09-01-73C dated Oct. 11, 1972.

To quote...."The 1973 standard 440 will be built with either the forged or cast crankshaft..........The cast crankshaft engines are identified by the stamped letter "E" below the build date on the cylinder block information pad".

I have personally pulled a couple of '73 350 hp engines with cast crank and the "E" stamping.
