Either way, I would just loosen up rod bolts on individual cylinders till it freed up, then figure out what went wrong. Has to be wrong cap, cap on backwards, or wrong sized rod bearings . Doesn't a 4.7 have cracked rods ? If so, a mistake here should be pretty easy to figure out . I would not think that you could have missed that during assembly though.
Once you have figured out which one is tight, time to do a little measuring .
I hate all those motors, blech

It's not a 4x so it'll have to come back out. I'm not sure what you mean by "cracked rods". When I became concerned with things being too tight I checked that all the rod caps were on correctly (not backwards) so I'm confident that's not the issue. I also looked very closely to see if I could visually see a difference in the caps compared to the rod i.e. color, machine marks, casting lines. I couldn't see anything obviously different.
