What is the difference in the V6 cranks? The 2.0, 2.4, & 2.5 appear the same except for the top crank bearing. What about the stroke & journal sizes? Thanks in advance Suprdave
Great new board

You got it. I just put a 2.5 crank in a '84 2.4 200 Merc. I had to use the upper berring with the newer crank but that's it as far as I know. There may be a difference with the oil pump drive gear, but since I don't run one, it isn't an issue for me.

Also the radius on the rod journals are different a bottom guided crank has more of a radius because of the closeness of the rod to crank relationship
