What cranks are these?

[poweredbylincoln]

Does anyone know what cranks these are? And if they are stock or modified?

Thank you

Looks like counter weighted 4 Cyl Model A or B crankshafts to me.

Seeing the Model A rear bumper brackets, I would say they are a pile of used stock A crankshafts. I don’t see any with B style counterweights or any that have been modified. You should be able to measure the main bearing journals with a tape measure and determine what they are. The B will be 1.998/1.999 or almost 2 inches. The A will be 1.625. You should be able to visually see that difference even if you don’t have a micrometer.

I agree with v8fordman. There's not a counterbalanced crankshaft in the bunch.

Looks to be a bunch of stock Model A cranks to me . . .

Thought I saw a few counter weights in there, but my eyesight isn't very good. What are all those things with the holes in them>> I've never seen a mofel crank before??

Counterbalanced cranks on the left and the non version on the right.
