These are 1937 Straight 8 Packard Rods. Showing the color of the babbitt, as it should be when the tinning, and pouring Temperatures of any bearings are right.
If the Babbitt comes out White, in color Temperatures were not right, and will have imperfections, seen, or unseen, as behind the bearings, against its shell, or backing.
You can see the bearings do NOT have babbitt laying on top of the metal, like water on wax, that is one way you can tell if the babbitt has stuck to the tinning, as just because the shell was tinned, does not mean by a long shot that it stuck.
Since they are drilled for wrist pin oil they are the Super 8 as opposed to those for the 120 eight. Should have 2.188 crank pins if standard.
As of 1937 the Super Eight was the old 320 CID Standard Eight, the 385 CID Super Eight having been dropped in 1936 at the end of the 14th series.
These engines were separate crankcase and block and had nine mains.
Wow, Thats a nice job Kohnke. Thanks for the pictures. I like the rod caps with the cooling fins. Scott
I was told by an old babbiter a long time ago the Packard engine was not designed to be rebuilt.

I have always found, that when some one says something is no good, and when others are doing it and working, the are at the end of there Aptitude!
Were the rods spun pored ?
