Urban myth.
Nobody in their right mind assembles a high rpm race engine with 1 connecting rod lighter than the other 7. It defeats the entire purpose of balancing the rotating assembly.
“Toyota said in a statement that the connecting rod in question was three grams under the legal minimum weight, and none of the other seven were found to be at fault.”
The one fact that has held true from the first engine built till today is you must have balance to hold things together and not vibrate apart. Related Articles - Travel a New Road to AAPEX this Season - Randy Breaux, Group President, GPC North America, Talks to AMN Drivetime - Holley’s Latest LS...
