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

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