This little gem came through our shop for some engine and chassis work. Cool car with a long history. Just thought you might enjoy the story... I did https://www.canadianhotrods.com/features.php?action=hotPage&ID=116&page=1&pg=18
Very cool! Never seen a stock rocker arm break like that… Where did you source the adjustable rockers from? Dare I ask how much they cost?
Not sure why the rocker broke. Nothing was binding and the valve wasn't stuck but it did have a lot of wear across the tip... maybe it got hot enough times that it fatigued and failed? The heads went to the machine shop for a rebuild and we found these rocker assemblies at Ross Racing Engines. They're very nicely made. The owners name is Tony. Leave a message, he calls back and will provide pricing.
