So this may be a bit of a dumb question but I want to be sure. I am on a serious serious time crunch with my motor being rebuilt (less than 24hrs deadline) and have a set of clevite HX mains on the way. (ACL hxs are on national backorder) and ACL std were too tight) I already have ACL rods clearanced in spec and a set of new ACL thrust bearings. Can you mix and match the thrust bearings to the Mains? (B18C1 w eagle rods stock crank)

 

They do completely different things in different locations; Yes, you can run whatever set of thrust bearings that suits your fancy.

 

Good to know, thanks!
