Well, you need to do what every engine builder does. You must measure the journal in every possible angle to make sure its round. You could also measure the con rod - you may be a REAAALLY lucky guy. If everything is within spec then sure you can reassemble, use plastigauge for one final check and be done with it. I'd say 50% chance crank is good, 90% con rod is toast.So any suggestions what the next step is?
There is no play when I did assemble this rod/cap with the new BE bearings and snugged up the bolts.
Judging by your last statement you may not be familiar with micrometers and bore gauges. Stop by your local engine builder, tell them your story and ask them (pay if you have to?) to show you how to measure crank and bore.
