I have a 66 with a 289 that I had rebuilt at a motorshop in town and after about 40thousand miles of no problems, three valve springs have broken on me with in about a month of eachother. I replaced one then another one a month later and the third one that broke was the first one i replaced that was new. I made sure the valves were adjusted corectly and the only thing that isn't stock is a very mild cam upgrade. I need help figuring out what this is so I can fix it. Has anyone else had this Problem?
Thanks in advance.
