identifying honda crankshaft

[daBoosted93]

I have a couple of crankshafts and am not sure which is which. I know i have a ls, b16 and gsr, and have looked all over the crank and cant find a pr3, p72 or pr4 stamp on it. is there any way of finding out what engine a crank goes to?

Don't all 3 have different strokes?

ya, but you have to measure that and i dont have the tool

Well the B16 and B18 cranks would be visually different. Or the difference in stroke should be noticable to the eye. You might be able to get away with a tape measure for the LS and GS-R cranks.
