FoMoCo claimed that they had a new alloy for the Y-block crankshafts in 1954. Which was the alloy? Except for the forged crankshaft have all y-blocks the same alloy? How about the South-American cranks?

Which was the material for the C1TE crank?

Have anyone increased the strength of the Y-block crank by rolled fillet?
I believe it will increase the fatigue strength a lot, may be as much as four times.

How about nitride and induction hardening on the Y-block cranks?

Are cracked y-block cranks a result of harmonics, i.e. lack of good vibration damper or balancer?

What about a 312 crank turned down to 292 journals, rolled fillets, and hardened?
Strong as a C1TE crank?
