Today I did the tinfoil trick and ended up adding shims to every rod. Guess what, they move like their supposed to when torqued up. Now pop the pistons back in and put the flywheel back on for the third time. Oh, I also got the side clearances corrected too.
I'll report back when I hang the starter back on but I'm sure I got it whipped.

Pete, your Rod People gave you a snow JOB. Unlike other Jobs, this one is Bad!
It is hard telling what kind of machine they bored the rods on, as there are many eye Brow lifters!
There 's no such thing as Align Boring a Rod, on any machine. Align Boring a bearing refers to Boring two or more bearings on a center line, such as Main bearings, and there is no assurance that would be done right by all the pictures that have been posted on this Fourm!

There is no way that a rod fit was the fault of the crank grinder. If your crank was off that far, the crank would not be useable. What they did was pass the buck, as you don't fit the crank to the Rod, you Fit the Rod to the Crank.
So, if you had to take Babbitt off the sides, as they were not cut to 1.625-00 -.008 thousandths, they didn't do there Job right.
I am also about 99.99 percent sure that the Rods are also out of alignment, and doubt if they do check them, or even have a machine to do so.
