First off I'm using a truck pan and tube for the 5.7 and mating it to a Challenger 5.7. I am trying to replace the main bolt on the number 4 main with one from the truck 5.7 because it has a stud on it that supports the oil tube. (sorry no pics right now) My worry is that I will end up scoring the main bearings somehow while swapping this out. I don't plan on pulling both bolts for that main cap, but I can if that's the way it should be done. Can I just pull the one side, replace the bolt and retorque? I guess I'm worried about the bearing shifting or something when I pull it and then me not noticing it and retorquing it and then the bearings get screwed up. Thoughts?
