Thanks, guys! Once again, real-world experience trumps theoretical Bovine Scatology!

In my case if the main caps I had would have fit with normal line boring I would have preferred to do that. As it was the block still needed a light line honing....
As a note, on 235-261 the two inner main caps have no locating dowels or machined register slots in the block. It's appears only the fit of the shoulder of the main bolts locates the inner main caps. That and the bearing shell......It's a poor design compared to other period inline engine like the GMC.
