What did you do for rods? Recondition? Lml?
I just had new bushings put in mine which was a pain in the ass since they’re tapered on the sides and need two oil holes drilled.
I put Fleece heads on that eliminate the injector cups, Mahle cast coated pistons. Crank and block was still standard size. Also SAC style injectors. New style drivers side exhaust manifold. New style oil cooler.
It’s a farm truck, If it goes another 378K it will outlast me.
