at first i thought maybe assembly error but the ammount of play between the bearings and the rod caps make me think his bearings may have the wrong ones. I could see an assembly error fucking up 1 or 2 rods at the most but the guy who built it seemed like he knew his shit for the most part on the technical side. If all the bearings are they same im gonna lean toward the problem being in the parts. I mean if you saw how much play there was youd be like WTF and i dont think they warped out that much unless they shrunk significantly even with the wear the bearings barely fit around the crank the needed to be forced on but move freely in the rob cap. ---

I can’t view the pics but… without seeing any. it’s not a matter of “Thinking” it should be machined or not. The engine is built with specific tolerences. Find the number and check the tolerances. It’ll be a yes/no answer, no thinking. But my mentality has always been… “just replace it if it’s in question” There’s nothing worse than every time you hear something or feel something in the engine bay you start thinking the worse case scenerio because you cut corners. For me it’s worth putting my mind at ease to just fix it THE BEST WAY I can. It’ll be cheaper than having to pull the motor a 2nd time. ---

the new shortblock is quite a price i think at this point it is ur best bet though just buy it, drop it in and dont worry about the bottom end too much anymore like lafengas said, you will feel better just knowing that everything is assembled correctly with correct parts ---

As far as milies the internals probally have about 800 milies on them. if that. i bought them brand new and put about 800 milies on them. i am really not sure what happend to them but i belive i might of gotten the wrong ones or something. ---

who did your bearing clearances? Are they sloppy fits like OEM v8s or tight, direct fit ones? What clearances did you decide to run? I think on my nissan, it was supposed to be .0018-.0030 but i am not positive… That was a few years ago… Who mic’ed up your rods and crank? ---

I think on my nissan, it was supposed to be .0018-.0030 but i am not positive… That was a few years ago… Who mic’ed up your rods and crank? i got the OEM GTE bearings… They have dffernet size bearings, you minus the number on the rod to the crank and you will get a number trough 1-5. So the bearings were never checked for clearance. atleast what i am aware of. ---
