The parts are not Eagle or Manley. They are offshore parts, but Brandon is one of the few who listen and respond to MOpar builders in terms of journal sizes and such. Depending on the machinist, some will say it need work, some will say they are fine. I've used several kits, all needed something, mostly rod reworking. But, the crank dimensions as shipped tend to be on the smaller side. So running it with a rod on the bigger end of the tolerance can lead to too much clearance. Also ,the chamfer for the oil holes tends to be very tapered on the journal. In one case, I've seen pics of it extending almost totally accross the bearing surface. That should be carefully inpected. In any case, unless the crank needs to be turned and polished to the next smaller size, there is no reason not to use them. And if that is the case, Brandon will ship a replacement for you. Even spending a little to fix them, it is a great deal on some decent parts. I have a 505" kit being ordered this weekend. That will make 4 from him.
