I know the stroke is the same, but are there any differences? I just bought a bare LQ9 block and and now looking for parts to put it together to build a 370ci engine (contemplating 4" crank for a 408 but thats another thread).

If there are any differences between these two cranks please educate me. If theres one I should opt for over the other let me know. It will be going in with forged rods and pistons. Most likely Eagle or Scat rods and I'm undecided on pistons.

 

the crank should be the same. the main difference between the rotating assemblies are the piston and pin assemblies
