Hay-Does anyone know if there is a difference in 6.9and 7.3 crankshafts?I have a book that is telling me the 6.9 has a 4.18 inch throw,and the 7.3 has a 4.11 throw.Is the difference in the rods or a missprint in the book?

 

They are the same. Bookmakers type like I doo.

 

4.18 is the correct stroke for both engines.
Crankshaft should be interchangable.

 

Thanks for the update-I kind of thought they had to be the same.
