interesting stuff Tom. Thanks for the link. I've had a GM HEI on the 258 for several years. I managed to lose a centrifugal weight (long story) and have had zero luck finding another one or another pair. Apparently, Mr. Goodwrench doesn't make them anymore. What I've been using is one stock weight and a spring from the Crane Cams adjustable vacuum advance kit on one side, and on the other side I'm using a weight and spring from one of those light weight Mr. Gasket HEI weight/spring sets which I do not like. Does anyone know where I can get stock weights? I've been to the junkyard on a few occasions also and what I came home with didn't work due to the size of the pivot hole. thanks Doug -------------- next part -------------- A non-text attachment was scrubbed...
