400 crank thrust width
I have a 400 crank I thought about having machined so I could turn the knocking 351M I took out of my bronco into a 400. The thrust width is supposed to be 1.125 +/- .001. This one is 1.140 and needs machining to clean up the surface. Are there wider thrust bearings available, or is this thing junk?

i don't have any reference at the moment to verify your specs but if it is indeed worn beyond spec, they add material by welding then machine it to spec. back in business. you could always just turn it in as a core on a fresh crank kit too.
