    Default 6.2L vs. 6.5L diesel Crankshaft interchangeability?

    Hello,

    I am looking at a replacement crankshaft for my 1985 M1009.

    Anyone know if I can replace my original:
    NSN 2815011489535 GM 23500246 CRANKSHAFT, ENGINE 6.2 LITER, UOC: 10E, 20E
    with:
    NSN 2815014113964 GM 23502596 CRANKSHAFT, ENGINE 6.5 LITER, UOC: 11E, 12E, 30E, 40E, 50E, 60E, 70E, 80E, 90E

    What are the advantages? Is the old crank cast vs. the new model forged?
    Or if not, what are the issues I will be facing?

    Welcome your expertise; need to decide soonest.

    Thank you,
    Jake

    They are not interchangeable.

    You're welcome, didn't catch your location till now, shipping would be expensive I would think, good luck with your project.
