Were the rods and wrist pins on 68-71 340s press fit or floating from the factory? I thought they were pressed, but what I have are floating. I may need to install new rod bearings, have one with uneven wear that is into the copper. I only have 2 of 8 pulled so far. Can I just get new bearings, check clearance and install, or will they need to be reconditioned? If the other bearings are OK, I may just replace this rod because it is an oddball 3418645 rod from a later motor, not a 2899469 340 rod like the other seven. A friend suggested that the uneven wear could indicate a tweaked rod. I hope to have the rest pulled after work tonight. I'm trying to avoid a complete redo on the short block. It was running fine, the only reason I'm getting into it is the motor is out while car is in the body shop and I wanted to know what the motor condition was and what parts it had. Looks like the car needs to go to the frame shop so any budget I had for the the motor in the near term has evaporated. I'm going to have to get it back together with a minimum of parts invested so I have a running motor. May still be able to install the heads and cam I already have but will go with the old J-heads if I can't figure out the difference I have in piston height.
