One light. Have run out of local sources. Looking for 261 rod-- weight on big end 515, total weight 855 or more. Any help on sources would be appreciated. Don't seen anything in Stovebolt swap meet. | | |

But the one rod was way-light and they would have had to make toothpicks out of the others. Machinist had access to other rods from a friend at another machine shop so initially was not concerned. Even though they were supposed to have come out of another 261, they were also light and had the casting no. the same as the one light one.
The five we are trying to match have the casting no. 964-GM146A
The light one had a casting number of 456.
So here we are...... | | |

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

I'm learning more about 261 rods than most people would care to know. Spoke to a bunch of folks yesterday including Patrick's and a guy in WA, "Buffalo".???
He verified what Tony said about the ...964 casting number being a 261 rod and said that the light rod with the ...456 apparently indicated a replacement rod. Now it makes sense that the entire set of six 261 rods from the other machine shop and the 6th one I had were all light.
I have now found three sources for a 261 rod. One is only about 20 miles from Omaha. If all works as planned, will probably make a trip to pick it up today. | | |
