Most engines have the decimal rounded to the two closest numbers beyond the decimal point. They are the same size for all intents and purposes. A power hone will change those decimal figures pretty quick if forged pistons are fitted. Those early Edsel engines had several high compression ratings that the later engines didn't have unless they were prepped for high performance applications.

In later years, Ford only made the three FE crankshafts. The one for the 360, the one for the 390/427, and the one for the 428. Toward the end of production the 390 crank was the main one for pickups and the 428 one was for industrial applications. They were used a lot for irrigation engines in the 70s & 80s. My Pop even used one to pump irrigation water for a long time.
