Hard to see because of the glare of the light off the
oil on the bearing, but you can see the bore mic marks on the bearing where I set the clearances up 3 years ago. This was in a 351C, which usually has a bad reputation for oiling the rods with high rpms. This engine was in the car for a year of limited street driving, then a season of bracket racing, launching at 5500 with wrinkle wall slicks, shifting at 7600 at times.
Oil pressure was 50-55 psi measured at the rear of the block. This was a #8 rod bearing.
Of course an S/O FE is a better design than the Cleveland block, as the S/O will
oil the mains and rods first, then get oil up top. The Cleveland pulls oil from the pump and can oil the lifters first. Most people will tell you that you absolutely need lifter bore bushings, they need to be restricted, blah, blah, blah, but there were no bushings in this engine...just correctly sized bores/lifters.
I would have reused all the bearings, but he's wanting a new engine built and we'll probably go with 2" rod journals instead of the 2.100".
