I was going to mention too that the number six cylinder looks like the piston to wall clearance was too tight, that's probably the reason for the pin galling.
What were the clearances on your bearings. If tight and the oil was not up to temp, that will scuff and kill them quick.
That is ok by Chrysler standards, but on the tight end.See more details of my project where I have more details of the build.
All of my mains were between .0015 and .002”.
Connecting rods were: .0015”, .0016”, .0016”, .0016”
Crank endplay: .005”
Yeah... finding that out.That is ok by Chrysler standards, but on the tight end.
That is the Chrysler minimum. Stay at .002 on your rebuild. You might want to investigate 0w40 synthetic for after the break in. Just for giggles, what was the ambient temps this engine was broken in/operated in? For instance, it is 100 today in New Jersey.Yeah... finding that out.

That must be infuriating after all the money a build costs. What did the re do entail cost and time wise?I had built an engine with .001 and it locked up after cam break in. Just to much heat on break in. Scuffed the walls pretty good.
