Did I just get hosed?

[gilberttitan08]

I just bought a 340 crankshaft, the last four casting numbers are only visible which are 3457, I know 68 cranks are 2532457. Are these numbers correct for a 340 forged crank?

Hard to tell with the info you gave. Did you pay for a forged crank and think you got a cast? You can look at it and tell the difference.

Even if it is a forged crank, you won't know if you got hosed until you take it to a machine shop and have them mic and mag it for cracks. Good luck!

Stand it up and give it a tap with a hammer on a counterweight. A forged crank rings with a very long decay time. Like 2 seconds. Maybe more. A cast crank just kinda clunks, with a sub 1 second decay.

The parting line and hammer ping test should tell you if it's forged or cast.

x2 on taking it to the machine shop for magnafluxing.
